The aim of the study is the assessment of accuracy for the diagnostic evaluation of Wilms tumor in the pediatric population in the era of contrast-enhanced CT scan using histopathology as a gold standard. Plain and contrast-enhanced abdominal Computed Tomography including pelvis and chest was performed in suspected patients with multiple axial sections with sagittal and coronal reconstructions. Patients were being followed, data was collected and recorded on proforma after histopathology. The patient's mean age for this study in years was 3.5 ± 1.2. Gender distribution showed 170 patients (54.6%) were male while the remaining 141 patients (45.33%) were female. Contrast-enhanced computed tomography showed sensitivity (90.36%), specificity (51.72%), diagnostic accuracy (72.34%), positive predictive value (68.18%), and negative predictive value (82.42%) confirmed on Histopathology as the gold standard. It is concluded from the results of this study that contrast-enhanced computed tomography proved high diagnostic accuracy positive predictive in the detection of Wilms’ tumor by taking histopathology as the gold standard.

Abstract Introduction: Postpartum haemorrhage is a major cause of maternal mortality. Although contrast-enhanced computed tomography (CE-CT) is useful to reveal arterial bleeding, its accuracy in postpartum haemorrhage is unclear. The aim of this study was to evaluate the accuracy of CE-CT scanning in detecting postpartum haemorrhage.Methods: This was a retrospective observational study. We included patients with postpartum haemorrhage treated by emergency physicians in collaboration with obstetricians. We calculated the sensitivity, specificity, and positive and negative predictive values for CE-CT scanning to detect arterial bleeding.Results: CE-CT scanning was performed in 52 patients, and 31 patients had extravasation. The sensitivity of CE-CT scanning to detect arterial extravasation was 100% (15/15), specificity was 28.6% (2/7), positive predictive value was 75% (15/20), and negative predictive value was 100% (2/2).Conclusion: We showed the sensitivity of CE-CT scanning to detect arterial extravasation in patients with postpartum haemorrhage to be 100%.
