Abstract:
Objective To explore the clinical value of multidetector CT angiography in the diagnosis of pulmonary em-bolism (PE). Methods Twenty-three PE patients diagnosed with CTPA were included in the retrospective study. Multi-ple plane reconstruction (MPR), maximum intensity projection (MIP), volume rendering technique (VRT) were performed to analyze the number of thrombi and type of PE. Results The CTPA of 23 patients revealed that totally 169 pulmonary arteries and their branches were affected, there were 13 right or left pulmonary arteries, 40 lobar arteries, 77 segment arteries, 39 subsegment or distal branches, respectively. The types of PE were 65 central, 72 eccentric, 2 luminal ad-hension, 30 obstruction, there were 3 cases of pulmonary infarction, 4 cases of mosaque, 8 cases of pulmonary hyper-tension, 9 cases of pleural ascites, 3 cases of hydrocardiac, 3 cases of fibrosis pulmonary ectasia. Conclusion CT an-giography of MDCT is a noninvasive, safe, rapid, effective exam method for the diagnosis of pulmonary embolism.
