The present study is designed to determine the frequency of splenic injury after blunt abdominal trauma and common types of trauma leading to it. Splenic injury carries immense medicolegal importance. Aim: To determine the diagnostic accuracy of ULTRASOUND in detection of visceral injury in blunt abdominal trauma considering CT as gold standard. Methods: This study was conducted at Department of Diagnostic Radiology, Pakistan Institute of Medical Sciences (PIMS), Islamabad. Study design was cross-sectional (Validation) study and the duration of the study was 6 months. The sample size was calculated by using WHO sample size calculator taking sensitivity 93.3% 2,6, specificity 85% 2,6, prevalence 65% 3, desired precision 10% and confidence interval of 95% it came out to be 141. More over purposive non-probability sampling technique was used for sample collection. Results: In this study mean ...

Results: In this study, out of 237 cases, majority of the patients i.e., 59(24.89%) were between 31-50 years, mean and sd was calculated as 53.65±5.78 years, 132(55.70%) male and 105(44.30%) were females, frequency of acute ischemic stroke (on gold standard) reveals 68(28.69%), diagnostic accuracy of NCCT scan with DWI MRI taking it as a gold standard in detection of acute ischemic stroke, which shows 66(97.06%) true positive, 2(2.94%) had false positive, 165(97.63%) had true negative while 4(2.37%) had false negative, sensitivity, specificity, +ve predictive value, -ve predictive value and accuracy rate was computed as 97.06%, 97.63%, 94.29%, 98.80% and 97.47% respectively. Conclusion: Diagnostic accuracy of NCCT Scan when compared with DWI MRI (being gold standard) for the detection of acute ischemic stroke reveals significantly higher diagnostic ...
