急性胸痛实施多层螺旋CT血管成像胸部三联检查的诊断分析

目的分析急性胸痛患者实施多层螺旋CT血管成像胸部三联检查的效果,为临床诊断提供参考。方法选取我院收治急性胸痛患者62例为研究对象,患者均采取64层螺旋CT联合血管造影检查,对患者冠状动脉、主动脉以及肺动脉进行图像重组,分析成像质量。结果 18例患者检查发现冠状动脉狭窄大于50%,28例患者为急性肺动脉栓塞,5例患者发生在胸主动脉夹层,检查图像质量主观评分均在2-4分,57例患者肺动脉增强后CT均值≥200HU,61例患者主动脉增强后CT均值≥200HU,平均扫描时间为(8.2±1.1)s,扫描范(27.61±1.62)cm。结论在急性胸痛诊断中,采用多层螺旋CT扫描能够在8s完成检查,得到主动脉以及肺动脉等图像诊断,具有实用价值。

Clinical Application of Multi-slice Spiral CT angiography Based Thoracic Triple Esamination on Acute Chest Pain Diagnosis

Objective To approach the clinical significance of multi-slice spiral CT angiography-based thoracic triple examination to acute chest pain diagnosis.Methods 64-slice CT was conducted for 62 cases with clinical acute chest pains as an initial symptom. Image reconstruction technologies including CMPR, MIP and VRT were adopted for the coronary artrry, pulmonary artery and aorta to assess the imaging quality. Results 28 cases were diagnosed as coronary atenosis, 18 cases were diagnosed coronary stenosis greater than 50% and 5 cases were dignosed with thoracic aortic dissecti. 57 cases of patients with pulmonary arterial enhancement CT value is greater than or equal to 200HU, 61 cases of patients with aortic enhancement CT value is more than or equal to 200HU, the meanscanning time is (8.2+1.1) s, the scanning range is (27.61+1.62) cm. Conclusion Multi-slice spiral CT angiography-based thoracic triple examination can be finished in around 8s in a one-off effort to make a correct diagnnsis of diseases of aortic and pulmonary artery.
