摘　　要：目的评价磁共振磁敏感加权成像(SWI)在轻型颅脑外伤的诊断及应用效果。方法选择46例轻型颅脑外伤患者,所有患者均先后行头颅CT检查、SWI检查,分析CT检查、SWI检查对患者的检出符合率及挫裂伤灶检出率。结果 SWI检查对轻型颅脑外伤患者的检出符合率97.83%明显高于CT检查的86.96%,差异具有统计学意义(P<0.05)。20~30岁组、30~40岁组和40~50岁组的SWI检查的检出率分别为100.00%(18/18)、100.00%(15/15)、92.31%(12/13)。20~30岁组、30~40岁组和40~50岁组的CT检查的检出率分别为94.44%(17/18)、86.67%(13/15)、76.92%(10/12)。SWI检查对患者挫裂伤灶检出率96.00%明显高于CT检查的80.00%,差异具有统计学意义(P<0.05)。结论 SWI诊断能够有效判别轻型颅脑外伤患者疾病情况,该诊断方式的检出符合率明显较高,值得应用推广。Objective To evaluate the effect of magnetic resonance susceptibility weighted imaging （SWI） in diagnosis and application of mild craniocerebral trauma. Methods A total of 46 patients with mild eraniocerebral trauma all received head CT examination and SWI examination. The detection coincidence rate and detection rate of contusion lesions of CT examination and SWI examination were analyzed. Results The detection coincidence rate of SWI examination for mild craniocerebral trauma patients was 97.83%, which was significantly higher than 86.96% of CT examination, and the difference was statistically significant （P〈0.05）. The detection rates of SWI examination in 20-30 year-old group, 30-40 year-old group and 40-50 year-old group were 100.00% （18/18）, 100.00% （15/15） and 92.31% （12/13） respectively. The detection rates of CT examination in 20-30 year-old group, 30-40 years group and 40-50 years-old group were 94.44% （17/18）, 86.67% （13/15） and 76.92% （10/12）respectively. There was significant difference in the detection rate of SWI examination and CT examination between 20-30 year-old group, 30-40 year-old group and 40-50 year-old group （P〈0.05）. The detection rate of SWI examination for patients with contusion lesions was 96.00%, which was significantly higher than 80.00% CT examination, and the difference was statistically significant （P〈0.05）. Conclusion SWI examination can effectively identify the condition of patients with mild craniocerebral trauma. The coincidence rate of this diagnostic method is obviously higher, and it is worthy of application and promotion.
