Öğe Advanced Magnetic Resonance Imaging Findings of Renal Hydatid Cyst(2014) Erdem, Gülnur; Burulday, Veysel; Alkan, AlpayAbstract: Hydatid Cyst, a serious health problem in the developing countries, is a zoonotic infection formed by echinococcus. Though liver or lung involvement is often, kidney involvement is rarely seen and represents for only 2 to 3 per cent of all cases of hydatid disease. An adult case referred who had multiple cysts in liver and large, solitary cyst in the kidney. We aimed to present magnetic resonance spectroscopy (MRS) and diffusion weighted magnetic resonance (DWI) findings of the hydatid cyst's. This is the first study that shows the MRS and DWI results of the renal hydatid disease. The mean ADC (apparent diffusion coefficient) value of the renal hydatid cyst was 2554x10-6 mm2/s on DWI and high signal intensity was detected compared with the renal parenchyma. MR spectroscopy at TE of 31 shows prominent alanine peak in addition to small amino acid peaks. Advanced MRI studies such as DWI and MRS can provide supplementary information both in the post-treatment period and in the diagnosis by bringing non-invasive approaches.Öğe Comparing clinical and functional outcomes of anterior cruciate ligament reconstruction using sonoelastography(Turkish Assoc Trauma Emergency Surgery, 2025) Erdogan, Eralp; Gunes, Zafer; Kaya, Ozgur; Sahan, Mehmet Hamdi; Burulday, Veysel; Vergili, Ozge; Serbest, SancarBACKGROUND: Injuries to the anterior cruciate ligament (ACL) are prevalent, particularly following athletic incidents. Most clinicians use MRI for diagnostic purposes and therapy assessment, but it can present challenges in terms of cost and accessibility. While ultrasound guidance (USG) is more readily available, it is inadequate for diagnosing ACL injury in isolation. Therefore, our study aimed to evaluate the effectiveness of sonoelastography, a novel method for assessing tendon injuries, in the context of anterior cruciate ligament (ACL) injuries. METHODS: This study involved a cohort of 45 patients who fulfilled the designated inclusion criteria. We selected the patients from a cohort of 105 individuals who underwent anatomical ACL restoration at the orthopedics and traumatology clinic between 2017 and 2020. The clinical examination results and the stability and quality of the ACL in patients who underwent ACL reconstruction were compared with those from magnetic resonance imaging (MRI) and stress echo laxity (SEL) testing. RESULTS: The study comprised 40 individuals with a mean age of 30.7 +/- 1.4 years. The patients' Lysholm scores exhibited considerable enhancement post-operation, with a mean increase from 2.2 +/- 0.9 pre-operation to 6.1 +/- 1.6 post-operation. The Lachman, anterior drawer, and pivot-shift tests demonstrated improvements relative to the preoperative values. No substantial difference was observed in the single-leg hop test relative to the unaffected side. The SEL findings indicated that 15.6% of the healthy ACL instances were categorized as type 2a, 68.9% as type 2b, and 15.6% as type 3a. In the reconstructed ACL cohort, 17.8% were categorized as type 2a, 62.2% as type 2b, and 20% as type 3a. No substantial statistical difference was detected between the healthy ACL and the reconstructed ACL. No occurrences of type 3b or type 4 were identified in any of the patients. CONCLUSION: We used SEL to find a torn ACL and check its stability and condition after the ligament was reconstructed with a graft. We utilize SEL, or stress sonoelastography, to monitor graft viability and evaluate the progression of ACL injuries. It is also beneficial in evaluating whether the restored ligament possesses a functional structure akin to that of a normal ligament. Moreover, considering its accessibility, cost-effectiveness, replicability, and patient preference, it may provide a more advantageous alternative to MRI.Öğe Effects of contrast material on the metabolite ratios in single-voxel MR Spectroscopy of intraaxial brain tumors(Churchill Livingstone, 2012) Alkan, Alpay; Burulday, Veysel; Oztanir, Namik; Dogan, Metin; Erbay, Mehmet Fatih; Kocak, Ayhan; Aralasmak, AyseAim: The purpose of our study was to determine whether the administration of contrast material affects the results of MR Spectroscopy (MRS) in different intraaxial brain tumors. Materials and methods: Thirty-three patients (median range 46.72 +/- 2.95, range 9-77) with intraaxial brain tumors underwent MRS before and 5 min after intravenous administration of gadolinium based contrast material at the standard dose of 0.1 mmol/kg (Gadodiamide or Gd-DOTA). Metabolite ratios (N-acetyl aspartate (NAA)/Creatine (Cr), Choline (Cho)/Cr. and NAA/Cho) were calculated. Results: There was no significant difference between the pre and postcontrast MRS spectra as regards to NAA/Cr (p:0.4), Cho/Cr (p:0.2), and NAA/Cho (p:0.2) ratios obtained from the intraaxial brain tumors. Conclusion: Contrast material administration did not change the metabolite ratios of MRS. Contrast administration would be useful in guiding voxel localization in MRS evaluation of intraaxial brain tumors. (C) 2012 Elsevier Ltd.

Suspicion, early diagnosis, debridement and anti-fungal treatment are important prognostic factors. The most common clinical manifestations of rhinocerebral mucormycosis are fever, headache, facial and ocular oedema. Invasion of surrounding tissues, the eye, skull base and brain is critical for disease progression. The purpose of this study was to investigate the predictive value of blood parameters in patients with mucormycosis. The preoperative 10-day blood parameters of 23 patients with clinical, radiological and pathological diagnoses of mucormycosis were compared in terms of etiology, gender and site of involvement. When the results were compared, the neutrophil-lymphocyte ratio (NLR) on days 1, 2, 5, 7, 8, 9, and 10 was significantly higher in patients with skull base involvement compared to those without skull base involvement (p<0.05). When comparing the regions of involvement, a significant correlation was found between cranial and turbinate involvement and between lamina papricea and ocular involvement (p<0.05). It was suggested that the NLR rate could be predicted as a poor prognostic factor in patients with mucormycosis.Öğe Kadın pelvik kitlelerinin benign-malign ayırımında difüzyon ağırlıklı MRG bulgularının farklı `b' değerleri kullanılarak değerlendirilmesi(İnönü Üniversitesi, 2010) Burulday, VeyselBu çalışmanın amacı, jinekolojik pelvik kitle ön tanısı almış kadın hastalarda kitlelerin farklı `b' değerleri kullanarak difüzyon ağırlıklı MRG bulgularının tanıya katkısını araştırmaktır. Çalışmaya Ekim 2009 ile Kasım 2010'da, Radyoloji Anabilim Dalı MR Ünitesi'ne pelvik kitle ön tanısıyla pelvik MR tetkiki istenen 15?82 (ort: 43) yaş aralığında 167 malign ve benign lezyon içeren 154 olgu dahil edildi. Bu hastalardan DAG ile sırasıyla b250, b500, b750, b1000 gradient değerlerinde difüzyon ağırlıklı EPI görüntüler alındı. Pelvik kitle saptanan olgularda lezyonlardan ADC değerleri ölçüldü. Malign lezyon saptanan 47 olgunun ortalama ADC değerleri (b250, b500, b750, b1000) (1.19x10?3, 1.12x10?3, 1.05x10?3, 0.94x10?3 sn/mm2), benign lezyon saptanan 120 olgunun ortalama ADC değerlerinden (b250, b500, b750, b1000) (2.17x10?3, 2.04x10?3, 1.97x10?3, 1.94x10?3 sn/mm2) düşük ölçüldü ve istatistiksel olarak anlamlı bulundu (p<0,05). Çalışmamız farklı b değerlerinde planlanmış olup tüm değerlerde malign ve benign kitleler arasında anlamlı istatistiksel farklar bulundu. Ancak b 500 altı değerlerde görüntü rezolüsyonu azaldığını ve lezyonların saptanmasının güçleştiğini saptadık. Pelvik bölge değerlendirmelerinde b 500 ile b 1000 arası değerlerin kullanılmasının daha uygun olacağının kanaatindeyiz. Sonuç olarak DAG'ın, konvansiyonel görüntüleme yöntemlerine eklenerek rutin kullanıma girmesinin pelvik kitlelerin malign ve benign ayırıcı tanısında önemli katkılar sağlayacağını düşünmekteyiz.Öğe Kronik Böbrek Yetmezliğine Bağlı Gelişen Posterior Lökoensefalopati: Manyetik Rezonans Görüntüleme Bulguları(İnönü Üniversitesi Tıp Fakültesi Dergisi, 2010) Burulday, Veysel; Erbay, Mehmet Fatih; Doğan, Metin; Göktan, Aslı; Alkan, AlpayPosterior reversibl ensefalopati sendromu çocuklarda nadir olarak görülen klinik ve radyolojik bir sendrom olup hipertansif ensefalopati, böbrek yetmezliği, immunsupresif ilaçlarla tedavi, sıvı retansiyonu, eklampsi, ve transfüzyon başlıca etiyolojik nedenler arasındadır. Bu raporda, dört yıldır kronik böbrek yetmezliği nedeniyle takip edilen, nöbet geçirme ve hipertansif atak ile çocuk polikliniğine başvuran ve yapılan MRG incelemesinde posterior reversible ensefalopati tanısı konulan yedi yaşındaki bir kız hastanın tanı ve takip MRG inceleme bulguları sunulmaktadır. Hastanın takip MRG incelemesinde posterior reversibl ensefalopati sendromunun olası komplikasyonlarından olan kanama gelişmiştir. Nöbet ile gelen hipertansif çocuklarda ayırıcı tanıda posterior reversibl lökoensefalopati sendromu düşünülerek beyin MRG ve difüzyon MRG incelemesi rutin olarak yapılmalıdır.Öğe Morphometric Analysis of Female Pelvic Cavity Among Turkish Population: A Radiological Study(Springernature, 2025) Canbolat, Mustafa; Aydin, Merve; Bilge, Damla; Kaya, Anil; Arslan, Ahmet Kadir; Burulday, VeyselBackground This study aims to reveal the characteristics of pelvic morphology in adult women within the Turkish population and to investigate age-related changes in pelvic region morphometry. Materials and Methods The study was conducted using CT images of 324 healthy women aged 18-60. Results A negative correlation with age was identified in all anatomical conjugate, obstetric conjugate, and diagonal conjugate values (p < 0.001). Furthermore, the differences between these pelvic diameters and age groups were statistically significant (p < 0.001, p < 0.001, p = 0.001). We did not detect any lateralization in the pelvis, except for the way the bones that make up the pubic symphysis meet each other. A significant difference was found for the subpubic angle among the age groups (p < 0.001). The distance between the anterior superior iliac spines (IADs) was positively correlated with age, and the differences in IADs values between age groups were also significant (p < 0.001). We found a significant difference in the pelvic inclination at the level of the inlet and outlet values among age groups (p < 0.001, p = 0.001). Conclusion It was observed that approximately 25% of our study cohort exhibited a spinous process extending downward from the superior margin of the greater sciatic notch, a feature that has not been previously documented in the literature. This spine may create pressure on the neurovascular structures passing through this region. We believe this structure deserves consideration in the causes of painful hip conditions.Öğe Noticable Findings in Cranial MRI of the Patients with Idiopathic Intracranial Hypertension(Sage Publications Inc, 2022) Cankaya, Imran; Muluk, Nuray Bayar; Burulday, Veysel; Bilgili, M. Yasemin Karadeniz; Ozdemir, AdnanObjectives Idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure. We investigated the optic nerve, Meckel's cavity, internal carotid artery (ICA) and pituitary findings of IIH by Cranial Magnetic Resonance Imaging (MRI). Methods Cranial MRI images of 35 adult patients with IIH and 35 adult subjects with normal cranial MRI results (control) were evaluated. Optic nerve diameter (OND), optic nerve sheat diameter (ONSD), OND/ONSD ratio, ON tortuosity, ON protrusion, posterior scleral flattening, ICA transverse diameter, CSF distance in Meckel's cavity and ICA transverse diameter/CSF distance in Meckel's cavity ratio, and pituitary gland measurements (height and transverse dimension; and Optic chiasm- pituitary gland distance) were measured. Results OND and ONSD of the IIH group were significantly higher than those of the control groups at anterior and posterior measurements (p < 0.05). OND/ONSD ratio of the IIH group was lower at anterior measurement; and higher at the posterior measurement than the control group (p < 0.05). Right ICA transverse diameter and bilateral CSF distance in Meckel's cavity of the IIH group were higher than those of the control. Optic chiasm- pituitary gland distance of the IIH group was significantly higher than that of the control group (p < 0.05). Conclusion OND/ONSD ratio is different in anterior and posterior measurements. So we recommend measuring OND and ONSD separately in IIH patients to use in the clinical practice. Similarly, optic chiasm-pituitary gland distance is also another point to note for IIH patients on MRI. Our paper adds new approach to IIH in terms of OND/ONSD ratio.Öğe Possible predictive clinical and radiological markers in decision making for surgical intervention in patients with Chiari Malformation type 1(Taylor & Francis Ltd, 2022) Yuksel, Ulas; Burulday, Veysel; Akkaya, Suleyman; Baser, Selcuk; Ogden, Mustafa; Alhan, Aslihan; Bakar, BulentBackground The first aim of this study was to compare the clinical data and posterior fossa morphometry obtained during the admission to the hospital between control group individuals (who had not Chiari Malformation (CM) type 1) and CM type 1 patients treated surgically or not. The second aim was to create a valid and reliable scale that can predict the decision-making for surgical intervention simply and easily in these patients. Materials Medical data and radiological images of 70 CM type 1 patients during their admission to the hospital were compared with the data of 69 control group individuals. Results Conservative treatment and/or follow-up was applied to 58 (82.9%) patients, and 12 (17.1%) patients underwent surgery. ROC analysis showed that the presence of myelopathy, tonsillar herniation >8 mm, Chamberlain line >84 mm, McRae line >44.50 mm, and odontoid process-McRae line angle <10.50 degrees could be used as predictive markers in decision-making for surgical intervention (p < 0.05). Logistic Regression analysis revealed that symptoms severity, and McRae line value would be the 'best parameters' in decision-making for surgical intervention (p < 0.05). A scale named the CHIASURG scale developed using this study's parameters showed that the parameters of 'depth of tonsillar herniation', 'Chamberlain line', and 'McRae line' could predict the surgical intervention risk. Conclusion It was found that symptoms severity and McRae line value could be used as predictive markers in decision-making for surgical intervention. Additionally, it was concluded that a new scale called CHIASURG could predict surgical intervention risk validly and reliably.Öğe Shear Wave Elastography Assessment of Achilles Tendon Stiffness in Asymptomatic Patients with Psoriatic Arthritis(Mdpi, 2026) Burulday, Veysel; Dag, Nurullah; Uslu, Aysun Gunduz; Yolbas, ServetObjectives: We aimed to evaluate Achilles tendon stiffness characteristics in asymptomatic patients with psoriatic arthritis (PsA) using shear wave elastography (SWE). Methods: In this prospective case-control study, 34 asymptomatic PsA patients and 34 age- and sex-matched healthy controls underwent bilateral Achilles tendon evaluation with grayscale ultrasonography and SWE. Tendon thickness was measured 3 cm proximal to the calcaneal insertion. Shear-wave velocity (m/s) and Young's modulus (kPa) were obtained under standardized acquisition conditions, including five-star motion stability and >= 90% reliability. Results: Achilles tendon morphology and thickness did not differ between PsA patients and controls (p > 0.05). In contrast, SWE demonstrated higher tendon stiffness in the PsA group. Mean shear-wave velocity was significantly greater in PsA patients for both the left (4.89 +/- 2.52 m/s vs. 3.23 +/- 0.41 m/s; p < 0.001) and right tendons (4.88 +/- 1.94 m/s vs. 3.12 +/- 0.30 m/s; p < 0.001), with corresponding increases in Young's modulus (all p < 0.001). SWE demonstrated good group discrimination, with shear-wave velocity achieving AUC values of up to 0.90 in differentiating PsA patients from healthy controls. Conclusions: SWE may reflect biomechanical tendon alterations in PsA, even in the absence of clinical symptoms, and may serve as a complementary imaging tool in the assessment of tendon involvement.Öğe Sonoelastographic evaluation of diaphragmatic thickness and stiffness in dialysis patients(Bmc, 2025) Dag, Nurullah; Berktas, Haci Bayram; Uslu, Aysun Gunduz; Burulday, VeyselObjectives This study aimed to quantitatively and noninvasively assess diaphragmatic alterations in patients with end-stage renal disease undergoing hemodialysis (HD) or peritoneal dialysis (PD) using ultrasonography (US) and shear wave elastography (SWE). Methods This prospective cross-sectional study included 69 dialysis patients (HD, n = 37; PD, n = 32) and 60 demographically matched healthy controls. Right hemidiaphragm was evaluated using greyscale US and SWE through the 8th-10th intercostal spaces in the mid-axillary line. Thickness and stiffness were measured at end-expiration and peak inspiration phases. Clinical data, laboratory parameters, and dialysis-related metrics were recorded. Comparative and correlational analyses were performed using appropriate statistical methods. Results At peak inspiration, the measurements were 2.24 +/- 0.25 mm and 25.61 +/- 6.15 kPa for the HD group, 2.53 +/- 0.23 mm and 32.79 +/- 5.31 kPa for the PD group, and 2.86 +/- 0.29 mm and 47.68 +/- 6.67 kPa for the control group. Significant differences were observed between the groups for both parameters (p < 0.001). At end expiration, diaphragm thickness and stiffness were 1.69 +/- 0.20 mm/19.46 +/- 4.37 kPa, 1.75 +/- 0.19 mm/22.62 +/- 4.84 kPa, and 2.00 +/- 0.19 mm/33.26 +/- 4.62 kPa in the HD, PD, and control groups, respectively. There were significant differences between the groups (p < 0.05). ROC analysis indicated excellent diagnostic performance of these parameters for distinguishing dialysis patients from controls (AUC 0.806-0.987). Furthermore, diaphragm parameters correlated significantly with dialysis duration, adequacy, comorbidity, and serum albumin levels. Conclusion Diaphragm thickness and stiffness are reduced in dialysis patients, especially those on hemodialysis. US and SWE may serve as early imaging biomarkers for respiratory sarcopenia.Öğe Sonographic evaluation of diaphragm thickness in pediatric patients with steatotic liver disease(2025) Doğan, Adil; Güngör, Şükrü; Burulday, VeyselAim: The most common liver disease in children is metabolic dysfunction-associated steatotic liver disease. We expect increased diaphragm thickness in pediatric patients with hepatosteatosis. We aimed to compare diaphragm thickness in children with hepatosteatosis with that in the control group and to discuss the results in light of the current literature. Materials and Methods: The study included 56 patients with metabolic dysfunction-associated steatotic liver disease and 78 healthy controls. The diaphragm measurement of the patient and control groups was performed from the anterior caudal part of the diaphragm at the end of expiration from the right and left sides. Results: Diaphragm thickness, BMI, weight, and height Z scores were significantly greater in the group with fatty liver. We found a significant positive correlation between the stages of fatty liver and anthropometric measurement Z score values with diaphragm thickness. Conclusion: The current study found that diaphragm thickness was thicker in pediatric patients with hepatosteatosis than that in healthy individuals and was positively correlated with anthropometric measurements. However, further studies are needed to evaluate diaphragmatic muscle function.
