【摘要】：目的探讨应用盆腔磁共振成像(MRI)原始数据重建在体女性骶前血管三维模型的方法及意义。方法对2012年2-5月广州医科大学附属第一医院25例因盆腔良性肿瘤患者手术前行盆腔MRI检查,以e-THRIVE序列获取所有MRI原始数据,应用Minics10.0软件重建骶前血管三维图像。结果骶前区血管三维重建均可清晰地显示腹主动脉、下腔静脉、双侧髂总、髂外及髂内动、静脉;25例患者中18例显示骶正中动脉,6例显示骶正中静脉及部分横干静脉。18例骶正中动脉均从腹主动脉分叉,平均直径为2.3(1.2~3.6)mm;6例骶正中静脉均汇入左侧髂总静脉,平均直径为3(1.7~4.6)mm。结论利用e-THRIVE序列MRI扫描盆腔血管,可构建盆腔血管三维重建模型,且骶前区的骶正中动脉显影率高,部分病例可显影骶正中静脉及横干静脉。
[Abstract]:Objective to study the method and significance of using pelvic magnetic resonance imaging (MRI) original data to reconstruct the three dimensional model of female presacral vessels in vivo. Methods from February to May 2012, 25 patients with benign pelvic tumors in the first affiliated Hospital of Guangzhou Medical University were examined by pelvic MRI before operation. All the original MRI data were obtained by e-THRIVE sequence, and three dimensional images of presacral vessels were reconstructed by Minics10.0 software. Results Three-dimensional reconstruction of presacral vessels could clearly display abdominal aorta, inferior vena cava, bilateral common iliac artery, external iliac artery and internal iliac artery. The median sacral vein and partial transverse trunk vein were found in 18 of 25 patients. The mean diameter of the median sacral artery was 2.3 (1.23.6mm) and the mean diameter was 3 (1.74.6) mm. The mean diameter was 3 (1.74.6) mm. Conclusion the three-dimensional reconstruction model of pelvic vessels can be constructed by using e-THRIVE MRI, and the development rate of the median sacral artery in the presacral area is high, and some cases can develop the median and transverse trunk sacral veins.
