摘　　要：目的探析螺旋CT和MRI对肝脏囊性病变的诊断作用。方法选取2017年3月至2018年1月期间收治的68例肝脏囊性病变患者作为研究对象,对比分析CT和MRI对肝脏囊性病变不同病变的影像学特征,对比CT和MRI检查结果,同时对比两种检查方式对肝脏囊性病变的诊断敏感性、特异性。结果 CT检查肝脏发育性囊性病变率88.89%,炎性囊性病变率83.33%,肝脏恶性肿瘤囊变病变率91.43%分别低于MRI检查的100%、95.83%、97.13%,两组数据差异具有统计学意义(P<0.05)。MRI对肝脏囊性病变诊断敏感性为93.18%、特异性为95.83%虽明显高于CT检查的79.55%和79.17%,两组数据差异具有统计学意义(P<0.05)。结论 CT和MRI均能有效诊断肝脏囊性占位,且准确率均较高,但核磁共振诊出率、敏感性、特异性更高,对肝脏囊性病变更适用。Objective To explore the diagnostic role of spiral CT and MRI in liver cystic lesions. Methods A total of 68 cases of liver cystic lesions admitted between March 2017 and January 2018 were selected as study objects. Compared and analyzed the imaging features of different liver cystic lesions treated by CT and MRI.Compared the results of CT and MRI,Meanwhile,Compared the sensitivity and specificity of the two examination methods to the diagnosis of liver cystic lesions. Results CT examination showed that the rate of hepatic developmental cystic lesions was 88.89%, inflammatory cystic lesions was 83.33%,and the rate of hepatic malignant tumor cystic lesions was 91.43% lower than 100%,95.83% and 97.13% of MRI examination,respectively. The difference between the two groups showed statistical significance(P<0.05). MRI was 93.18% sensitive to the diagnosis of liver cystic lesions, and 95.83% specificity,although significantly higher than the 79.55% and 79.17% of CT findings,the difference between the two groups was statistically significant(P<0.05). Conclusion Both CT and MRI can effectively diagnose hepatic cystic space occupying,and the accuracy rate is higher.ButMRI is more sensitive and specific,which is suitable for the changes of liver cystic diseases.
