主动脉夹层的影像学诊断

目的:探讨不同影像学检查方法对主动脉夹层的诊断价值.方法:将26例主动脉夹层患者的超声检查(TTE),X线平片,CT,MRI,血管造影检查结果汇总分析.结果:X线平片提示性阳性率69%(18/26);超声检查阳性率77%(20/26),检测出破裂口16例,检出率62%.CT阳性率92%(24/26)检测出破裂口8例,检出率31%.超声结合CT阳性率100%(26/26),检测出破裂口20例,检出率77%.心血管造影4例,4例阳性,4例检出破口;MRI检查6例,6例阳性,5例检出破口.结论:超声检查和CT扫描是诊断主动脉夹层最快捷实用的影像学检查手段,二者结合可提高主动脉夹层的阳性诊断率及破裂口检出率.

Diagnosing Aortic Dissection with Doppler Echocardiography

Objective: To investigate the value of different image analysis in diagnosing aortic dissection.Method: The result of TTE,plain film radiography,CT,MRI and angiography of 26 patients with aortic dissection were analyzed.Result: The non-specificity masccline rate of plain film radiography is 69%(18/26).The masccline rate of sonography is 77%(20/26),of which 16 were detected crevasses and detection rate is 62%.CT masccline rate is 92%(24/26) with 8 cases were detected crevasses and detection rate is 31%.Sonography combined with CT masccline rate is 100%(26/26),of which 20 were detected crevasses and detection rate is 77%.cardiac angiography is 4 cases,with 4 masccline and 4 cases were detected crevasses.MRI check is 6 cases with 6 masccline and 5 cases were detected crevasses.Conclusion: Sonography and CT scanning are the quickest and most practical means to diagnose aortic dissection.The two combined method can improve diagnosing aortic dissection and detection rate of crevasse.
