Abstract:
Objective To evaluate the clinical value of pulmonary vessels with multi slice spiral CT pul-monary angiography(MSCTPA) in pulmonary embolism(PE). Methods MSCTPA was performed in 23 cases sus-pected patients. All the primitive images of pulmonary vessels were produced at the console workstation. The distri-bution of pulmonary vessels emboli was evaluated from different angle. Results Spatial relationship and anatomical details of pulmonary arteries and veins could exactly be shown on all pulmonary vessels three-dimensional images in above-mentioned patients. On the basis of MSCTPA, PE could be diagnosed definitely, in addition, collateral circula-tion formation could be clearly demonstrated. Of 23 patients, PE were found in 16 cases by MSCTPA. Two hun-drends and sixty-four emboli were demonstrated in total, among which there are 149 embolilocated in segmental ater-ies and 115 in subsegmental ateries(grade 5～6 branches). The minimal diameter of pulmonary atery with thrombus was 1mm. Conclusion MSCTA has very high clinical value in detecting segmental and aubsegrnental pulmonary thrombi in PE patients, and provides useful inforrnation for the diagnosis and treatment of pulmonary vascular dis-eases.
