目的 比较320排CT Surt-start成像和动态容积扫描对肝移植术后肝动脉并发症的临床应用价值.方法 回顾性分析2009年4月至2011年9月中山大学器官移植中心20例肝移植病例,320排螺旋CT对肝移植术后20例患者先后行两组CTA检查,动态容积组采用动态容积扫描模式,Surt-start组采用螺旋扫描.对比剂碘普罗胺(370 mgL/ml),流速6 ml/s,动态容积组剂量为50 ml,Surt-start组剂量为1.5 ml/kg.比较两组肝动脉强化峰值时间、最佳动脉期时间、强化峰值、强化绝对峰值及肝动脉分支显示情况.结果 动态容积组肝动脉的强化峰值时间、最佳动脉期时间分别为(21.5±2.5)、(22.4±3.3)s,Surt-start组为(19.5±1.8)s,两组间差异有统计学意义(P=0.001、P=0.000);两组强化峰值、强化绝对峰值及肝动脉分支级数差异均无统计学意义(P值分别为0.884、0.934、0.569).动态容积组显示肝动脉细微病变优于Surt-start组.结论 320排CT动态容积扫描具有对比剂剂量低、图像质量高的优点,可作为肝移植术后肝动脉并发症随访的有效手段.
目的 比較320排CT Surt-start成像和動態容積掃描對肝移植術後肝動脈併髮癥的臨床應用價值.方法 迴顧性分析2009年4月至2011年9月中山大學器官移植中心20例肝移植病例,320排螺鏇CT對肝移植術後20例患者先後行兩組CTA檢查,動態容積組採用動態容積掃描模式,Surt-start組採用螺鏇掃描.對比劑碘普囉胺(370 mgL/ml),流速6 ml/s,動態容積組劑量為50 ml,Surt-start組劑量為1.5 ml/kg.比較兩組肝動脈彊化峰值時間、最佳動脈期時間、彊化峰值、彊化絕對峰值及肝動脈分支顯示情況.結果 動態容積組肝動脈的彊化峰值時間、最佳動脈期時間分彆為(21.5±2.5)、(22.4±3.3)s,Surt-start組為(19.5±1.8)s,兩組間差異有統計學意義(P=0.001、P=0.000);兩組彊化峰值、彊化絕對峰值及肝動脈分支級數差異均無統計學意義(P值分彆為0.884、0.934、0.569).動態容積組顯示肝動脈細微病變優于Surt-start組.結論 320排CT動態容積掃描具有對比劑劑量低、圖像質量高的優點,可作為肝移植術後肝動脈併髮癥隨訪的有效手段.

Objective To evaluate the clinical application comparison of Surt-start imaging and dynamic volume scanning acquired from 320-detector row computed tomography (CT) for the diagnosis of hepatic artery complications after liver transplantation.Methods Retrospective analysis was conducted for 20 patients undergoing 320-slice CT scanning.Aquilion One scanner after liver transplantation was performed from April 2009 to September 2011.Dynamic volume scanning group employed dynamic volume scanning pattern while Surt-start group used helical scanning pattern.The contrast medium (Ultravist,370 mgI/ml iopromide) was infused at 6 ml/s with a total dose of 50 ml in dynamic volume scanning group versus 1.5 ml/kg in Surt-start group.Two groups were compared with regards to hepatic artery enhancing peak time,the best arterial phase time,maximum peak enhancement of artery,maximum absolute peak enhancement of artery and branches of hepatic artery.Results The hepatic artery enhancing peak time and the best arterial phase time was (21.5 ± 2.5) s and (22.4 ± 3.3) s in dynamic volume scanning group versus (19.5 ± 1.8) s in Surt-start group.And there was significant inter-group difference(P =0.001,P =0.000).The maximum peak enhancement of artery or the maximum absolute peak enhancement of artery and branches of hepatic artery had no inter-group difference.Two groups showed no difference in displaying hepatic artery anastomosis and variations.Dynamic volume scanning group was better than Surt-start group in displaying hepatic artery microscopic lesions.Conclusion 320-detector CT dynamic volume scanning has the advantage of low-dose contrast medium.Capable of acquiring overall accurate imaging process of hepatic artery,it is effective for follow-ups of hepatic artery complications after liver transplantation.
