Non-stenotic MCA plaques are
effectively detected using HR-VWI. Coupled with a derived biomarker of
laterality index, this method may be promising for the identification of BAD in SSIs.

Figure 3: Comparison of laterality index
(L_index) of LSA morphological parameters between the plaque and non-plaque
groups. The L_Index of LSA branches and total length in the plaque group were significantly
higher (*, p<0.05) than those in the non-plaque. There was no statistical
difference in L_Index of LSA stems.
Figure1: Plaque group, a 69-year-old female
with right lenticulostriate infarction (B) and non-stenotic MCA (A). C: HR-VWI
shows the plaque on the upper wall of the MCA-M1 segment (red arrow). LSA skeletons
(G-I, from D-E) are shown. The numbers of LSA stems and branches and the total
length of LSA on infarcted and healthy sides were 4/6/125 mm and 3/4/89 mm, respectively.
The calculated laterality indexes were 0.14/0.30/0.17, respectively.
