Abstract Objective: To investigate the effects of 3.0T magnetic resonance susceptibility weighted imaging(SWI) and MRA in thrombosis and according vascular responsibility in acute cerebellar ischemic stroke and the clinical application value. Methods: Thirty cases of acute ischemic stroke in cerebellum(<72 h) were enrolled with conventional brain MRI, MRA and SWI. Susceptibility vessel sign(SVS) on SWI and arterial stenosis or occlusion were analysed and correlated. Results: Hyperintensity on DWI and hypointensity on ADC maps were shown in all 30 cases of acute cerebellar ischemic stroke. Among all, 70%(21 cases) were from inferior posterior cerebellar artery, 23.3%(7 cases) were from anterior posterior cerebellar artery, and 6.7%(2 cases) were from anterior cerebellar artery. MRA showed cerebellar arterial stenosis or occlusion in 14 cases(46.7%), but failed in the rest 16 cases(53.3%). SVS were shown in 26 cases(86.7%) with double SVS in 7 cases, while the 4 cases had no SVS(13.3%). SWI and MRA showed significant difference in displaying SVS in cerebellar arteries and responsible vessels(χ2=10.800, P=0.002). Conclusion: SWI and MRA showed obvious consistency in displaying responsible vessels in acute cerebellar ischemic stroke. SWI was much better than 3D-TOF-MRA in detecting small arterial thrombosis.
