Clinical MRI Cutoff Points for Predicting Lacunar Stroke May Not Exist: Need for a Grading rather than a Dichotomizing System

Abstract

A clinically significant proportion of clinical MRI lacunae are associated with underlying nonlacunar mechanisms. Decisions regarding the extent of diagnostic procedures in patients with subcortical infarcts can be guided by the point value in terms of the stroke syndrome and infarct patterns, as well as the size of infarct.
