    Diagnostic errors in computed tomography outsourcing: Analysis of a single center
    (2019) Karavas, Erdal; Hirik, Erkan
    Aim: The reporting of medical imaging with outsourcing is used by many hospitals in Turkey. The aim of this study was to evaluate outsourced computed tomography (CT) reports and determine any errors made. Material and Methods: The study was planned with a prospective design. The reports of the CT tests taken during 2017 by an outsourced company of 35 randomly selected patients were compared. In the comparison, findings which could lead to a change in diagnosis and treatment were labelled as “significant” and findings which would not lead to a change in diagnosis and treatment were labelled as “non-significant”. Findings reported in the study comparison but not mentioned or written incorrectly in the outsourced company report were classified as “absence” and any finding that was written but not present was labelled as “extra”. Results: The study included the examsimages and reports of 35 patients, comprising 18 (51.4%) males and 17 (48.6%) females with a mean age of 49.37± 23.66 years. A major error was found in 27 (77%) cases. No statistically significant difference was determined in the significant, non-significant, absent and extra data according to patient age (p>0.05). Conclusion: There should be an implementation of regulations for clinicians to be able to re-use the diagnostic algorithm. Residential employment of radiologists should be encouraged rather than outsourcing.

    Exploring the quadriceps muscle architecture variations in various sports disciplines: a comparative analysis of football, taekwondo, and athletics
    (Edizioni Minerva Medica, 2024) Ciftci, Rukiye; Kurtoglu, Ahmet; Car, Bekir; Karavas, Erdal; Eken, Ozgur; Soyler, Mehmet; Ardigo, Luca P.
    BACKGROUND: The purpose of this study was to comprehensively investigate and compare the architecture of the quadriceps muscle in football, taekwondo, and athletics, shedding light on potential differences and providing valuable insights for athletic training and performance enhancement. METHODS: Thirty-five athletes (football[N.]=14. [7 women, 7 men]; taekwondo [N.]=11. [6 women, 5 men]; athletics [N.]=10. [5 women, 5 men]) aged 17-21 years participated in the study. After participant demographic data were collected, 2D real-time B -mode ultrasound (USG) and right (R) and left (L) leg quadriceps muscle group rectus femoris (RF), vastus intermedius (VI), vastus lateralis, pennation angle (PA), RF cross-sectional area (CSA), and subcutaneous fat thickness were determined. RESULTS: In the study, in female athletes, R-RF+VI (P=0.04, ES:4.34), R -VI (P=0.01, ES: 6.1), R-RF: (P=0.009, ES: 7.9), R-CSA (P=0.04, ES: 5.2), L-RF (P=0.002, ES: 10.4) and L-CSA (P=0.007, ES: 7.7) significant differences were found in favor of the Football group. In male athletes, R-CSA (P=0.004, ES: 9.05), L-RF (P=0.05, ES: 3.5) and L-SFT (P=0.00, ES: 13.6), there was a significant difference in favor of the Football group. L -PA (P=0.009, ES: 6.2). L -PA (P=0.009, ES: 6.2) was significantly higher in the male Taekwondo group. CONCLUSIONS: Our research findings show that there is a significant relationship between the type of exercise performed and the structural differences observed in the quadriceps muscle. Consequently, it is highly recommended to consider the outcomes of our study for enhancing the efficacy of training programs in the domains of football, taekwondo, and athletics.
