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. © 2014 pakistan journal of medical and health sciences. all rights reserved.
