目的探讨主动脉夹层(Aortic dissection,AD)多排螺旋CT血管成像(MSCTA)和彩色多普勒超声的影像学表现及诊断价值。方法回顾性分析40例42人次AD的MSCTA和彩色多普勒超声影像学资料。结果 40例42人次检查中,MSCTA诊断准确率达100%,特异性达78.6%,彩色多普勒超声诊断准确率100%,特异性为62.5%,二者联合应用诊断准确率达100%,特异性达100%。结论 MSCTA和彩色多普勒超声各具优点,两者联合应用可为AD的诊断、预后评估、治疗方案的选择和术后随访提供准确的信息。
Objective To investigate the imaging findings and diagnostic value of multi-slice spiral CT angiography (MSCTA) and color Doppler ultrasound in patients with aortic dissection (AD). Methods Retrospective analysis of 40 cases of 42 cases of AD MSCTA and color Doppler ultrasound imaging data. Results The accuracy of MSCTA diagnosis was 100% and specificity was 78.6% in 40 cases and 42 cases. The accuracy and accuracy of color Doppler ultrasonography were 100% and 62.5%, respectively. The diagnostic accuracy of the two methods was 100% Specificity up to 100%. Conclusion MSCTA and color Doppler ultrasound have their own advantages. The combination of the two can provide accurate information for the diagnosis of AD, prognosis evaluation, treatment options and postoperative follow-up.
