Objective To evaluate the diagnostic value of Spiral CT pulmonary angiography (SCTPA) in acute pulmonary thromboembolism. Methods Retrospective analysis of SCTPA changes in 43 patients with acute pulmonary embolism. Results An embolism was found in254 of795 pulmonary arteries in 43 cases (32 %) . Direct signs included partial filling defect (60 %) , complete occlusion (30 %), railway-track sign (3 %) , mural filling defect (2 %) ,low perfusion and varied lung density (5%). Indirect signs included pulmonary artery dilatation in 13 cases(30 %) , focal fine pulmonary blood vessels 22 (51 %) , mosaic sign 3 (7 %) , effusion 7 (16 %) , atelectasis 7(16 %) , cuniform change 4(9 %) , ground glass shadow 6 (14%). Conclusion SCTPA is an effective method for the diagnosis of acute pulmonary thromboembolism, which is accurate , easy to perform and noninvasive.
