Abstract:
Objective To explore the diagnostic value of MR susceptibility weighted imaging (SWI) in the cerebral micro-bleedings(CMBs). Methods Conventional MR sequences including TSE , FLAIR and SWI sequences were per-formed in 50 patients as well as SWI sequence.The numbers of CMB and sensitivity of positive rare on SWI and conventional sequences were compared and statistically analyzed. Results SWI sequences clearly exhibited dot,stripe,round or ring-shaped low signal shadows. With diameter from 0.4 to 6.5 mm. Cerebral microbleeds mainly located in cortex, subcortex and basal ganglia in 50 patients. Compared to 23 cases with spin echo TSE, and 20 cases with FLAIR. Conclusion SWI has predomin flilt advantage over conventional MRI sequences in detecting CMBs. SWI provides an important reference for the treatment and evaluating prognosis of cerebral infarction.
