摘要
目的:探讨螺旋CT三期增强扫描在肝血管瘤中的影像特点及诊断价值。方法:搜集46例肝血管瘤患者在螺旋CT平扫后进行螺旋CT三期增强扫描的资料。扫描范围为全肝;层厚为5mm^8mm,pitch=1.2,对比剂为优维显(300mgI/ml),采用单相期团注法注入剂量为80ml^100ml,流速2.5ml/s^3.5ml/s。延迟时间:动脉期(HAP)延迟25s^30s、门静脉期(PVP)延迟65s^70s、延迟期延迟3min^10min。结果:动脉期强化病灶49个(84.5%),门脉期对比剂逐渐向病灶中心充填,9个无明显强化病灶开始强化。延迟扫描见造影剂进一步向病灶中心填充,48个病灶(82.6%)完全填充为等密度,其余10个(17.2%)病灶部分充填。结论:肝血管瘤螺旋CT三期增强的各期大多数有典型特点,在诊断及鉴别诊断中具有重要的价值。
Objective To investigate the imaging features of 3-phase contrast-enhanced spiral CT scanning and the value of diagnosis in hepatic hemangioma. Methods 50 cases of hepatic hemangioma scanned by 3-phase contrast-enhanced spiral CT after common scan . Scan region： whole hepatic, thickness 5 mm ～8 mm, p = 1.2; all used. single phase to inject Ultravist （300 mgl/1） 80 ml ～ 100 ml, injected rate 2.5 ml/s ～3.5 ml/s. delayed time： hepatic arterial phase,25 s～30 s,portal venous phase,65 s ～ 70 s, delayed phase 3 min ～ 10 min. Results 49/58 （84.5%） of hepatic hemangiomas had potentialization at hepatic arterial phase （ HAP）, and centripetal oriented enlargement of the regions at portal venous phase （ PVP）, 9 hepatic hemangiomas begin potentialization. In delayed phase, 48/58 （ 82.6% ） of the hepatic hemangiomas showed completely homo- genenous patentialization or iso-density filling, others 10/58 （ 17.2% ） presented part filling. Conclusion majority hepatic hemangiomas have typical exhibition in 3-phase contrast-enhanced spiral CT scanning, and the 3-phase contrast-enhanced spiral CT scanning has an important value for the diagnosis of hepatic hemangiomas and compare with primary liver cancer.
