摘要
目的探讨肝硬化患者多层螺旋CT肝静脉造影的合适条件。方法60例临床确诊肝硬化患者随机分为三组:N1、N2和N3,每组20例,20例年龄相匹配的非肝硬化患者作为对照,N1及对照组造影剂剂量1.5mL/kg,N2及N3剂量为2.5mL/kg,注射速度均为3.5ml/s,N1、N2及对照组肝静脉期扫描时间为70s,N3肝静脉期扫描时间为80s。结果N1组肝静脉CT值、肝实质CT值及两者差值分别为(121.09±16.78)Hu、(95.91±14.16)Hu和(25.18±11.60)Hu,对照组分别为:(160.55±14.27)Hu、(109.20±5.79)Hu和(51.35±12.25)Hu,肝硬化组均明显低于对照组(P<0.05)。N2组分别为:(130.54±15.31)Hu、(98.55±14.86)Hu和(31.36±12.62)Hu、相对于N1组肝静脉和肝实质的CT值均有一定程度上升,但差别没有显著性(P>0.05);N3组分别为:(136.92±17.53)Hu、(89.43±15.48)Hu和(43.42±10.71)Hu,相对于N1组肝静脉CT值显著增加,同时肝实质密度轻度降低,两者差值明显提高(P<0.05)结论联合大剂量持续注射和延迟扫描技术,多层螺旋CT能对肝硬化患者肝静脉作出满意的评价。
Objective To explore the optimal situation ofhapetic vein using multi-slice CT in cirrhosis. Methods 60 patients with liver cirrhosis patients were randomly divided into three groups： N 1 ,N2and N3,each one was 20 cases. 20 cases of age-matched patients without fiver cirrhosis served as control group. Iodine contrast agents were used with injection rate of 3.5ml/s, The doses of contrast agent were 1.5 mL/kg in group N1 and control, were 2.5 mL/kg in group N2and N3. The scanning delay time in group N3 was 80s, and 70s in rest. Results The CT values ofhapetic vein ,liver parenchyma and the difference-value between the two were, respectively, （121.09 ± 16.78）Hu,（95.91 ± 14.16）Hu,and （25.18 ± 11.60）Hu in group N1, and （160.55 ± 14.27）Hu, （109.20 ± 5. 79）Hu,（51.35± 12.25）Hu in control group, （130.54 ± 15.31）Hu,（98.55 _± 14.86）Hu, （31.36 ± 12.62）Huin N2, （136.92± 17.53）Hu, （89.43 ±15.48）Hu,（43.42 ± 10.71） Hu in N3.Group N1 was significantly lower than control group （P 〈 0. 05）.Com- pared to group N l, the CT values in group N2 increased to a certain extent, but there was no significant difference （P 〉 0.05 ）. In group N3, the CT values of hepatic vein and the difference-value were significantly higher than that in group N1 （P 〈 0. 05）. Conclusion Combined with high-dose injection and delay scaning, multi-slice CT can evaluate the hepatic vein of patients with cirrhosis satisfactorily.
