摘要
目的:对比多排螺旋CT直接法下腔静脉成像测量径线,与间接法下腔静脉成像测量径线是否存在差异。方法:回顾性分析30例(男14例,女16例,年龄23~65岁,中位年龄44岁)直接法下腔静脉成像的患者图像,收集30例(男10例,女20例,年龄20~66岁,中位年龄43岁)腹部增强检查患者静脉期图像。通过GE adw4.6后处理工作站对原始图像行MIP、MPR重建,分别测量下腔静脉右心房入口、第一肝门、肾盂、左右髂总静脉分叉上方平面的长径、短径,并测量左肾静脉汇入下腔静脉上方1cm处下腔静脉CT值。结果:下腔静脉右心房入口、第一肝门、肾盂、髂总静脉分叉上方平面的长径及短径,直接法成像分别为(3.02±0.44,2.06±0.32)、(2.29±0.49,1.39±0.52)、(2.46±0.44,1.73±0.45)、(2.30±0.38,1.66±0.46);间接法成像分别为(2.88±0.43,1.95±0.31)、(2.37±0.59,1.17±0.37)、(2.28±0.32,1.63±0.31)、(2.25±0.21,1.47±0.34),两者之间无明显统计学差异。直接法左肾静脉汇入下腔静脉上方1 cm处CT值为313.43±50.90HU远高于间接法的95.50±22.17HU。结论:多层螺旋CT直接法下腔静脉成像与间接法下腔静脉成像,下腔静脉的不同层面径线测量无明显差异,直接法成像管腔内造影剂浓度高于间接法,显示下腔静脉更好,测量结果为正确评估下腔静脉疾患提供参考数据。
Objective： To measure the inferior vena cava diameters by direct and indirect MSCT angiography, and analysis whether there is difference between them. Method： Collecting 30 cases （M 14 cases, F 16 cases, ages 23～65 y, middle age 44y） which were underwent direct inferior vena cava venography, and collecting 30 cases （M 10 cases, F 20cases, ages 20～66 y, middle age 43y） of whole abdominal contrast enhanced CT, get the venous phase image. Original data were transferred to GE adw4.6 workstation for post-processing including MPR, MIP. The major axis, minor axis were individually measured, at the levels of its entrance to the right atrium, the portahepatis, the renal pelvis, above the junction of iliac vein. Measure the CT values where above 1cm the level left renal venous joined Inferior vena cava. Result： At the levels of its entrance to the right atrium, the portahepatis, the renal pelvis, above the junction of iliac vein, the major axis, minor axis of direct CT phlebography individually were （3.02 ±0.44, 2.06 ±0.32）, （2.29 ±0.49, 1.39 ±0.52）, （2.46 ±0.44, 1.73 ±0.45）, （2.30 ±0.38, 1.66 ±0.46）, of indirect phlebography individually were （2.88 ±0.43, 1.95 ±0.31）, （2.37 ±0.59, 1.17 ±0.37）, （2.28 ±0.32, 1.63 ±0.31）, （2.25 ±0.21, 1.47 ±0.34）, there is no obviously difference between them. The CT values of direct CTP where above 1cm the level left renal venous joined Inferior vena cava is （313.43 ±50.90） HU, much higher than the indirect CTV （95.50 ±22.17） HU. Conclusion： There was no significant difference between direct CTV and indirect CTV of the inferior vena cava diameters.
