Abstract:
Objective To explore the differential diagnosis among lacunas, demyelination and perivessel space in the aging brain. Methods T1 and T2 weighted image for 100 aging brains were analyzed retrospectively. All examinations were performed using GE 1.5 T scanner. Results In 100 subjects, 61 had multiloci of infarction and constituted a total of 110 loci. They located at pontine(17), cerebellum(14), lentiform nucleus(24), internal capsal(10), thalamus(12), periventricular and head of caudate nucleus (26), semioval centrum (7). They were round, elliptic, triangle, curve and irregular in shape, respectively. Ninety-five patients had 125 countable perivessel spaces. They located at ganglia (84) and semioval centrum (41). Demyelination was seen in 71 subjects and involved pontine and semioval centrum. Conclusions Most of lacuna, demyelination and perivessel space is distinguishable based on their signal, shape and location.
