[摘要]目的 探讨肝脏转移性肿瘤的血供及螺旋CT特点。方法 回顾性分析67例经手术或病理活检证实的肝脏转移性肿瘤的各期特征。结果 67例中24例(35.8%)各期无明确强化,43例(64.2%)显示不同期不同程度的强化。肝脏转移性肿瘤有少血供(24例)、多血供(25例)、富血供(18例)三种。不同性质的肿瘤其动、门脉期的强化改变有所不同。结论 对于转移性肝癌,螺旋多期增强扫描是有价值的。

[ Abstract] Purpose To analyze the enhancement findings of 67 cases with hepatic metastases on helical CT scans ( arr.erial - phase and portalphase)and discuss the characteristics of blood supply with them.Methods CT findings in 67 patients with hepatic rnetastases were rctrospectively analyzecl. All cases were histologically proved. Results The metastases enhancements were observed in 43
cases(65 . 2% ) , no contrast lesions in 24cases
( 34. 8 010 ) . there were hypovascular
( n = 24) , hypervascnlar( n = 25) and extra - hypervascular( n = 18) patterns in hepatic
metastases . The contrast enhancement pattems were clifierent in arteriaJ - phase and portal - phase. Conclusions Multi - phase spiral C,T scanning is valuable in hepatic
metastases .
