COMPARATIVE EVALUATION OF DUPLEX SCAN AND TIME OF FLIGHT MAGNETIC RESONANCE ANGIOGRAPHY FOR EXTRACRANIAL CAROTID ARTERY STENOSIS IN ANTERIOR CIRCULATION ISCHEMIC STROKE PATIENTS

Abstract

Background: Duplex scanning is now the most widely used method of assessing anomalies in carotid 
arteries. Carotid disease is more accurately assessed by adding color coding, and test sensitivity is 
100%. Duplex scan results are dependent on the operator's accuracy. However, literature data is scarce 
in the Indian context.
Aim: The present study aimed to comparatively assess Duplex scan and Time-of-Flight Magnetic 
Resonance Angiography for extracranial carotid artery stenosis in anterior circulation ischemic 
stroke.
Methods: The study assessed 134 subjects from both genders who presented to the Institute with 
Anterior circulation ischemic stroke. Demographic data were gathered for all the subjects, followed 
by CCA, BULB, and ICA Doppler findings and MRA (TOF) of CCA, BULB, and ICA, and 
MRA(TOF) of CCA. The data gathered were statistically analyzed.
