摘 要: | 目的探讨多层螺旋CT及MRI在下腔静脉病变中的诊断价值。方法回顾性分析临床证实的80例下腔静脉病变的16层螺旋CT及0.35T MRI资料,CT以多期增强检查为主,MRI以平扫为主。重点分析下腔静脉病变部位、范围及性质。结果检出下腔静脉先天畸形9例(其中CT诊断5例,MRI诊断4例),下腔静脉栓子形成36例(其中血栓5例,癌栓31例;CT诊断32例,MRI诊断4例),布加综合征16例(其中CT诊断15例,MRI诊断1例),外压性狭窄12例(其中CT诊断8例,MRI诊断4例),支架置入3例(均为CT诊断)。结论多层螺旋CT及MRI能够快速、无创较为准确显示下腔静脉及其病变,值得临床应用。

Abstract: | Objective To explore the significance of multi-slice spiral CT scanning and MRI in diagnosis of lesions in inferior vena cava( IVC). Methods The data of 16- slice spiral CT scanning and 0.35 T MRI imaging of 80 patients with clinically confirmed IVC lesions were retrospectively analyzed. The CT scanning was given with multi- phase contrast- enhanced examination,MRI was mainly by plain scanning.These examinations were focused on analyzing the scope and nature of inferior vena cava. Results Among these 80 cases,9 cases were congenital malformation of IVC( 5 cases were diagnosed by CT scanning,and 4 cases by MRI),formation of emboli in 36 cases( including 5 with thrombosis,31 with cancer embolus; 32 cases were diagnosed by CT,and 4 cases by MRI),16 cases of Budd Chiari syndrome( diagnosed by CT scanning in 15 cases,MRI in 1 case),stenosis caused by external pressure in 12 cases( diagnosed by CT scanning in 8 cases,and by MRI in 4 cases),placement of stent in 3 cases( diagnosed by CT scanning). Conclusion Multi- slice spiral CT scanning and MRI can rapidly,accurately and non- invasively demonstrate IVC and its lesions,hence they are worthy to be applied for clinical diagnosis. |
