摘要
目的对比CT动态增强扫描与MR平扫两种方式诊断肝脓肿的临床价值。方法随机选取我院2014年6月至2015年6月期间因腹部不适行增强CT和MRI平扫检查的患者62例,其中有29例确诊为肝脓肿。结果 CT动态增强检出病变个数高于MRI检出病变个数,且两者差异具有统计学意义(P<0.05);CT动态增强检测肝脓肿病灶的能力高于MRI,且两者差异具有统计学意义(P<0.05);MRI图像上测出肝脓肿内部坏死囊腔与周围实性肿块面积比值相对较小,测出肝脓肿的内部坏死囊腔与周围水肿组织面积比值相对较大;成脓早期四种感染途径CT增强和MRI平扫影像表现存在不同之处。结论 CT动态增强扫描与MRI平扫对于诊断肝脓肿都有其优点与不足之处,两者配合使用具有较高的诊断价值。
Objective To investigate the clinical effect of enhanced CT and MRI plain scan in the diagnosis of hepatic abscess.Methods A total of 62 cases with abdominal discomfort in our hospital from June 2014 to June 2015 were selected and given enhanced CT and MRI plain scan,and 29 cases were diagnosed as hepatic abscess.Results The number of lesions detected by enhanced CT was higher than that detected by MRI,and the difference was statistically significant(P<0.05).The ability of enhanced CT to detect liver abscess was higher than that of MRI,the difference was statistically significant(P<0.05).The ratio of necrotic cystic cavity to solid mass around liver abscess was relatively small,and the ratio of necrotic cystic cavity to surrounding edema tissue area in liver abscess was larger on MRI images.There are differences in imaging findings between the four routes of infection at the early stage of abscess formation.Conclusion Enhanced CT and MRI plain scan have their advantages and disadvantages in diagnosis of liver abscess,and they have high diagnostic value in combination.
