TO EVALUATE THE DIAGNOSTIC ACCURACY OF COMPUTED TOMOGRAPHY OVER MAGNETIC RESONANCE IMAGING IN THE EVALUATION OF ACUTE AND SUBACUTE ISCHEMIC STOKE

Abstract :

AIM &OBJECTIVES:  To calculate sensitivityof Computed tomography with diffusion weighted magnetic resonance imaging as the gold standard in acute ischaemic stroke in adult patients admitted with clinically diagnosed acute CVA .  To find out the positive predictive values of Computed tomography in acute/subacute ischemic stroke. METHODS: 210 patients clinically diagnosed as acute/subacute ischemic stroke, referred to department of Radio Diagnosis were included in the study and have undergone Computed tomography and magnetic resonance imaging. Initial collection of patient details using prepared proforma and clinical history assessment to be done to know the onset of symptoms.Further Computed tomography imaging and MR imaging is done. Results and conclusion Total of 210patients with suspected stroke were taken for the study. Out of the 171 patients were true positive cases according to DWMR images. CT and MRI performed without any delay after onset of ischemic stroke resulted in significant differences in diagnostic accuracy. We got 89% sensitivity of CT over DWMRI in hyperacute phase, 83% in acute and 76% in subacute phases. Positive predictive value was low in hyperacute phase of ischemic stroke, where as it was 83% & 80% in acute and subacute phases respectively.
