Title: Evaluation of spiral CT in diagnosing pulmonary embolism
Abstract: Objective To evaluate the value of spiral CT in diagnosis of pulmonary embolism(PE).Methods By retrospectively analyzing imaging data of 13 patients with PE (plain spiral CT scan plus enhanced scan and pulmonary perfusion/ventilation imaging),some noticeable abnormal imaging signs were found. Results Among the 13 cases,emboli were found in the 9 patients of all on spiral CT pulmonary angiog-raphy(SCTPA) and 4 cases were detected by the pulmonary perfusion and ventilation imaging.7 cases had positive findings on plain SCT scanning images, which showed local reduced lung markings, dilated pulmonary artery,' mosaic' sign, pleural or pericardial effusion, local high attenuation centrally in the pulmonary arteries and lung infarction. Conclusion SCTPA is an effective,simple and safe technique for the diagnosis of PE. It is a reliable means in defecting PE. But for cases that could not use contrast media or cases that only underwent unenhanced CT because of nonspecific heart-pulmonary symptom,some noticeable abnormal signs of plain SCT scanning can be a clue to pulmonary embolism.
