目的：探讨1.5 T磁共振SWI在慢性高血压患者检测脑内微出血的应用及临床价值。方法选择采用1.5 T磁共振SWI行慢性高血压脑内微出血( Cerebralmicrobleeds ，CMB )检查的患者，采用1.5 T超导型全身磁共振扫描仪，常规扫描及SWI扫描序列；确认并分析高血压引起的低信号CMB灶情况。结果全部患者诊断为高血压病，脑微出血的SWI表现信号特点为斑点或圆形低信号，分布于基底节区、丘脑区、皮层和皮层下、脑干、放射冠区等。其中伴有脑出血发作史有27例，脑梗死患者43例(含腔隙性脑梗死)，排除脑血管畸形、脑肿瘤、脑外伤等。结论采用SWI检查显示慢性高血压脑内微出血症状，具有较高的敏感性与准确性，对早期预防脑出血及诊断脑卒中具有重要的指导作用。

Objective To study the application and clinical value of 1.5Tm agnetic resonance SW I in patients with chronic hypertension who were detected with cerebral microbleeds.Methods Sufferers undergoing the detection of chronic hypertension cerebral microbleeds by means of 1.5Tm agnetic resonance SW I were selected to accept routine scanning and SW I scanning sequence by 1.5Tm superconducting magnetic resonance im aging (MRI)scanner to identify and analyze lowsignal CMB focal condition caused by high blood pressure.Results All patients were diagnosed with hypertension characteristics,SW Im anifestation signals of cerebral microbleeds showed spot or circular lowsignals,distributed in basal ganglia region,lateral hypothalam icarea,cortical layer and subcortex,brainstem ,and corona radiata area. There were 27 cases of cerebral hem orrhage occurrence,43 cases of cerebral infarction (lacunar infarction included ),excluding cerebrovascular mal-form ation,cerebral tum or,and cerebral traum a.Conclusion SW I exam ination shows chronic hypertension cerebral microbleeds sym ptoms with high sensitivity and accuracy,and it plays an im portant guiding role in early prevention of cerebral hem orrhage and diagnosis of stroke.
