Öğe The effects of mineral water drinking and extra-abdominal pressure in elimination of attenuation artifacts on myocardial perfusion SPECT(2015) Bati, Fatih; Kekilli, Ersoy; Koksal, İsmail; Subasi, VedatAbstract: Myocardial perfusion scintigraphy is often used non-invasive diagnostic test for detection of coronary artery disease, myocardial viability, risk assessment and prediction of prognosis. The aim of this study was to evaluate of mineral water drinking and extra-abdominal pressure for elimination of attenuation artifacts on myocardial perfusion SPECT. A total of 27 patients (20 males, 7 females) who have suspicious findings on stress image were included in this study. If patients were reported ischemia or infracted on myocardial perfusion SPECT, they were excluded from the study. Stress SPECT imaging was repeated continuously three times following basal imaging, application of extra-abdominal pressure and after mineral water drinking. SPECT slices were obtained and "Summed Stress Scores" were calculated from three SPECT imaging. Double-blinded two clinicians visually evaluated these slices and have rated based on ease of evaluation as "best image", "Medium" and "Low". Additionally four groups were created from 4 rating areas which had Summed Stress Scores of 3 or above on Polar Map. Mineral water drinking and application of extra-abdominal may be better than basal imaging. Although a method selecting was difficult in theassessment of inferior and inferoseptal wall. Among the three applications for "Summed Stress Scores" were statistically significant differences with Friedman's test in the 1st, 2nd, 3rd and 4th groups (p=0.03, p=0.008, p=0.005 and p=0.0001, respectively). For evaluation of suspicious lesions in the anterior and anteroseptal region, basal imaging did not significantly differ from application of extra-abdominal pressure. Mineral water drinking (and close to the pressure) was found better than basal imaging in Group 2 and 3. In Group 4, there was not significant difference between the application of extra-abdominal pressure and mineral water drinking. On static images, we did not found any significant change for intrathorasic localization and axis of left ventricul among three SPECT. The most remarkable finding among three SPECT was gradually decreasing of hepatic uptake. We though that change in "Summed Stress Score" in both application of extra-abdominal pressure and mineral water drinking may only be due to decreases in hepatic activity associated with time.Öğe Normal range of BMD in proximal tibia as a different skeletal site at women(Kare publ, kare yayıncılık, sogutlucesme cad, no 76-103, ıstanbul, 34000, turkey, 2016) Aluclu, Mustafa Arif; Bati, Fatih; Kekilli, ErsoyOBJECTIVE: Osteoporosis is progressive metabolic bone disease that decreases bone density and features deterioration of bone structure. Dual-energy X-ray absorptiometry (DXA) is commonly used and reliable method to measure bone mineral density (BMD). Aim of this study was to determine normal ranges of BMD in left proximal tibia. METHODS: Fifty-five females were included in this study. BMD was measured at the lumbar spine and the left proximal tibia using DXA. BMD value of subregions in the left proximal tibia was significantly correlated with BMD value of the total lumbar spine (r=0.111-0.766). New average BMD values of the left proximal tibia were calculated according to age using linear regression formula, leading to average BMD value for the total lumbar spine (L1-L4) in normal population. New simulated T-scores for proximal subregions of the tibia were then calculated. RESULTS: T-scores for proximal subregions were not different from T-scores of total lumbar spine (p>0.05). CONCLUSION: It was concluded that proximal tibia is an ideal region for measurement of BMD in osteoporosis.Öğe Relationship between obesity and disability in adult individuals- retrospective screening(2017) Bati, Fatih; Ersoy, Yüksel; Büyükavcı, Raikan; Aktürk, Semra; Celbiş, OsmanAim: The objective is to examine the relationship between the musculoskeletal system (MSS)-based disability and the body mass index (BMI). Material and Method: The medical board reports (MBR) issued for patients in 2010, who applied for a disability report, were screened. From a total of 283 MBR’s, 99 disability reports were included. BMI was calculated and the relationship between disability ratios and BMI was examined. Findings: Out of the 99 patients, 77 were male and 22 were female. The mean age was 46.7±17.8, the BMI was 25.5±5.7 kg/m², the total disability ratio (TDR) was 46±24% and the MSS disability ratio was 33±23%. Both the BMI and age of the patient were significantly correlated with TDR values (p<0.05). The female mean age, the TDR, MSS disability ratio and BMI were higher compared to males. However, only the TDR was statistically significantly higher (p<0.05). 46% of the disability reports were due to acquired diseases (most commonly caused by arthrosis), 37% injuries (most frequently falls, work accidents and firearm injuries) and 11% were for congenital diseases. It was determined that the most patients, had applied to The Department of Physical Medicine and Rehabilitation and the most affected region was the lower extremities. Conclusion: It was identified that the increase in BMI may have an increasing effect on the disability ratios as well as the positive effect of disability on BMI. This fact should be taken into consideration when the ratio of disability is calculated in health board reportsÖğe Relationship between obesity and disability in adult individuals- retrospective screening(2017) Bati, Fatih; Ersoy, Yüksel; Büyükavcı, Raikan; Aktürk, Semra; Celbiş, OsmanAim: The objective is to examine the relationship between the musculoskeletal system (MSS)-based disability and the body mass index (BMI).Material and Method: The medical board reports (MBR) issued for patients in 2010, who applied for a disability report, were screened.

We investigated the usability of Tc-99m MIBI as a hepatobiliary scintigraphy radiopharmaceutical for diferential diagnosis of biliary atresia and hepatitis in experimental model. A total of 20 males Wistar albino rats who had weights ranging from 200-350 g were included in this study. Rats were randomly divided into 4 groups. Control group, sham operated group, biliary atresia group and chemical hepatitis group (with carbon tetrachloride) were created, respectively. Blood flow phases, consantration and early excreation phases was performed after an intravenous injection through the internal jugular vein of 37 MBq Tc-99m MIBI using a gamma camera. Dual late static images were obtained at the same position at 15, 30, 60, 90 and 120 min after injection. In control group, radiopharmaceutical passage into the small intestine was seen between 45 and 60 min and evidently seen between 120 and 150 min as large hyperactive focus on midline or non-linear (snaky) radiopharmaceutical accumulation at the level of kidney. In biliary atresia group, radiopharmaceutical concentration was seen normal in liver but passage into the small intestine was not seen all rats. In carbon tetrachloride group, blood flow, concentration and early excretion scintigraphic images did not differ from control group and radiopharmaceutical passage into the small intestine was seen between 45 and 60 min. Although radiopharmaceuticals passage into the intestine was not shown in all rats of biliary atresia group. We suggest that Tc-99m MIBI as a radiopharmaceutical of hepatobiliary scintigraphy would be the contribution of the differential diagnosis of biliary atresia and hepatitis in humans
