The application value of magnetic susceptibility weighted imaging in patients with hypertensive cerebral microbleedsing

Objective:To explore the application value of susceptibility weighted imaging in patients with hypertensive cerebral microbleeds.Methods:48 patients with hypertension cerebral microbleeds were performed with both SWI and conventional MRI sequences at 1.5 T MR scanner.The quantity,location and distribution of the cerebral microbleeds in all MRI sequences were compared.Results:The number of cerebral microbleeds were 169 detected by T2-weighted image,273 detected by T2 FLAIR and 1335 detected by susceptibility weighted imaging,respectively.There was significant difference between sequences for the detection of cerebral microbleeds(X2=9.92,P0.05).The locations of microbleeds were basal ganglia(31.6%),cortex-subcortex(24.9%),brain stem(18.7%),thalamus(18.6%),cerebellum(6.2%).Conclusion:Susceptibility weighted imaging is of great sensitivity for the detection of hypertensive cerebral microbleeds.This technique is so far the best sequence in detecting the cerebral microbleeds.
