Abstract

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.
