Diagnostic Accuracy of NCCT Scan with DWI MRI Taking it as a Gold Standard in Detection of Acute Ischemic Stroke

Aim: To determine the diagnostic accuracy of NCCT Scan with DWI MRI taking it as a gold standard in detection of acute ischemic stroke. 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 accuracy.
