摘要
目的:通过18例主动脉夹层的多层螺旋CT(MSCT)和CT仿真内镜(CTVE)表现,探讨CTVE技术在主动脉夹层诊断中的价值。方法:回顾性分析18例行MSCT增强扫描诊断为主动脉夹层病人,将原始数据在工作站上进行CTVE成像。18例中Ⅰ型主动脉夹层11例;Ⅲ型主动脉夹层7例。结果:11例Ⅰ型和7例Ⅲ型主动脉夹层清楚地显示了狭窄的真腔和扩张的假腔,以及主动脉夹层的部位、范围和分支受侵情况,并清晰地显示5例假腔内的血栓,10例主动脉夹层的内膜破口。结论:CTVE技术是一种无创伤、无痛苦,快捷、安全、有效的检查技术,能显示主动脉夹层的真假腔,显示破口的部位、夹层和假腔内的血栓,了解主动脉各分支有否受侵和受侵的程度,是诊断主动脉夹层有价值的检查方法之一。
Objective： To evaluate the application of multislice spiral CT （MSCT） and CT virtual endoscopy （CTVE） in the diagnosis of aortic dissection （AD）. Methods：18 cases with AD confirmed by MSCT imaging were retrospectively analyzed, and then the raw data were transferred to the workstation so as to reconstruct CTVE images. 11 Cases with type I and 7 cases with type Ⅲ were shown on CTVE. Results ：The narrow real cavities and dilated false cavities were displayed clearly in 11 cases of type I and 7 cases of type Ⅲ AD. The location, extension and arterial branches involvement of AD were also manifested. Thrombosis inside the false cavities were displayed clearly in 5 cases, the intimal tear in 10 cases was shown definitely in the CTVE images. Conclusion： Due to the non - invasiveness, painlessness, convenience, and safety of this examination technique, MSCT and CTVE should be the first choice for the detection of AD.
