Abstract:
Objective To evaluate the effectiveness of multiple spiral CT angiography in diagnosis of pulmonary embolism.Methods 16 patients clinically suspected of pulmonary embolism underwent multiple spiral CT angiography.Emboli were found in the 8 patients of all on multiple spiral CT angiography.5 of the patients were reexamined with this method 20 to 30 days after thrombolysis. Results In 8 patients with pulmonary embolism,43 vessels were involved with pulmonary embolism.The presence of pulmonary embolism on CT was seen as a total occlusion,partial filling defect,mural filling defect et al;dilated of pulmonary artery trunk;all signs with deceleration of pulmonary blood or “mosaic sign”. 5 patients were reexamined with this method.The emboli dissoved partly or entirely.Conclusion Multiple spiral CT angiography is a noninvasive and effective method for examining pulmonary embolism.
