Figure 2. — Methodology for measuring the lenticulostriate arteries (LSAs). A, The reconstructed coronal minimum intensity projection (MinIP; 30 mm thickness for presentation) image of a 54-year-old female with an acute infarction in left basal ganglia (arrow). B, Corresponding line tracings of the LSAs. Stems are labeled with Roman numerals, whereas branches are labeled with Arabic numerals. I-1, II-2, III-2 of the right LSAs and I-1, II-1 of the left LSAs originated from the common stem. The measurements are the lengths of each stem, respectively. Compared with the asymptomatic side, smaller number of LSA branches (6 vs 4) and shorter total lengths of LSAs (105.7 vs 93.9 mm) are observed in the symptomatic side.
