对于突发性非心性和非胸膜性胸痛,一般多考虑主动脉夹层动脉瘤,但病人可能有潜在的其它心血管病变,包括急性主动脉壁间血肿、漏血的主动脉瘤、动脉硬化性溃疡、心包炎及肺动脉栓塞。作者旨在评价螺旋CT在检查疑似主动脉夹层中的作用,并明确与之类似病变的性质及检出率。在GEHiSpead Advantage扫描仪上,采用标准程序进行扫描。增强前螺旋CT检查大血管及胸主动脉,厚度为10mm;然后在同一区域经静脉注射对比剂,用5mm
For sudden non-cardiac and non-pleuritic chest pain, aortic dissection is generally considered, but the patient may have other potential cardiovascular diseases, including acute aortic intramural hematoma, aneurysm, arteriosclerosis Ulcers, pericarditis and pulmonary embolism. The purpose of the authors is to evaluate the role of spiral CT in the detection of suspected aortic dissections and to identify the nature and detection rate of similar lesions. On the GEHiSpead Advantage scanner, the standard program is used for scanning. Enhanced anterior spiral CT examination of large vessels and thoracic aorta, the thickness of 10mm; then in the same area by intravenous contrast agent with 5mm
