ObjectiveTo explcer spiral CT of the liver abscess performance of three dynamic enhanced scanning and its diagnostic value. MethodsRetrospective analysis of clinical or pathologically confirmed by the 7cases of liver abscess CT, all patients were confirmed by CT scan and hepatic arterial phase, portal phase, balance of three dynamic contrast-enhanced scan, 1 case of delayed 7 minutes and then scan. Results7 cases of a total of 10liver abscess. Three dynamic enhanced MRI signs:6 typical abscess in four cases,showed double loop sign; an abscess had no enhancement phase enhanced the performance of balance on the edge just to clear; an edge enhancement was tumor size sign. 4 cases does not show typical abscess in three petal sign and tumor size sign; a show cluster sign andcontinuing to strengthen the sign, while changing the boundary clear and sharp. 4 of 10 abscesses in the liver parenchyma around the abscess,showed a transient arterial phase hepatic enhancement. ConclusionDynamic contrast-enhanced spiral CT scan three phases of liver abscess, especially in atypical liver abscesses had a higher diagnostic value.
