Silent Stroke: Role of carotid Doppler in hypertensive patients as a screening tool for the detection of silent stroke with MRI correlation

Abstract

Background: In the overall senior population, silent stroke range in prevalence from 8% to 28%. The 
public and medical community have become more aware of the silent stroke as a result of the growing 
senior population and advancements in imaging technology. Cognitive impairment and a higher risk of 
later stroke are linked to silent stroke. In this study, hypertension individuals' Carotid Doppler ultrasound 
is used as a screening tool for silent cerebral stroke using MRI imaging.
Methods: This prospective study was conducted in the Department of radiology and imaging Sciences 
Meenakshi Hospital, Thanjavur. A total of 45 hypertensive patients fulfilling the inclusion and exclusion 
criteria were recruited for this study who were referred with symptoms of silent stroke. The patients were 
screened for signs using carotid doppler ultrasound and compared with MRI brain findings. Findings 
were recorded in Microsoft excel and analysed using SPSS Version 26 and Epi-info statistical package, 
version 7.
