Evaluation of diagnostic value of pelvic MRI in endometriosis in comparison with surgical findings: A cross-sectional study.

Background: Endometriosis is a multifocal gynecologic disorder during the fertility period in women. Magnetic resonance imaging (MRI) is an important diagnostic modality for this disease and can either be used alone or along with transvaginal ultrasonography. Objective: This study aims to compare the accuracy of pelvis MRI in pelvic deep endometriosis with laparoscopic findings in women referred to Shahid Sadoughi hospital in one year. Materials and Methods: This cross-sectional study was conducted on 40 women suspicious of endometriosis who referred to Shahid Sadoughi hospital, Yazd, Iran from November 2020-2021. Based on clinical findings and history, participants were referred to the imaging center for pelvic MRI. Finally, the results of MRI and diagnostic laparoscopy were compared with pathologic findings. Results: The sensitivity and specificity of MRI for pelvic endometriosis were 94.8% and 20%, respectively. Also, the positive predictive value and negative predictive value of MRI were 90.2% and 33.3%, respectively. Conclusion: Laparoscopy is still the gold standard of endometriosis diagnosis, but MRI with susceptibility-weighted imaging sequence is the best noninvasive diagnostic method.

CT Scan Incidental Findings in Head Trauma Patients - Yazd Shahid Rahnemoun Hospital, 2005-2015.

BACKGROUND: Incidental findings are presented in radiology reports. Many of these findings do not require further investigation; however, some require further investigation and repeated imaging. The aim of this study was to determine the frequency of incidental findings on CT scans of patients with head trauma from 2005 to 2015. METHODS: This analytical cross-sectional study was conducted in years on 5,193 CT scan reports referred to Shahid Rahnemoun hospital in Yazd, Iran. The images were evaluated by consensus agreement of two radiologists. The relationship between age, sex and incidental findings was analyzed using the SPSS 20 software. RESULTS: A total of 5,193 subjects with a mean age of 34.16 ± 21.17 were examined. About 64% of cases were male. The frequency of incidental findings was 10.9%. The most common finding was calcification with a frequency of 3.3% and the least was Dandy Walker finding at 0.02%. There was no relationship between age, sex and the frequency of incidental findings. No significant trend was found between IFs frequency during ten years. CONCLUSION: The results of this study indicated that most incidental findings were related to benign findings, but also malignant findings were diagnosed.
