Abstract: Objective To evaluate the value of MSCTA in combination with CTV in diagnosis of pulmonary embolism and deep venous thrombosis (DVT) of lower limb. Methods 47 patients with pulmonary embolism proved clinically were examined with MSCTA using 120 kV,210 mA,collimater of 0.75 mm and the automatic bolus traching technique,the speed of contrast agent infu-sion was 3～4 m/s after 170 s delayed,venous scan of lower limbs was performed. Results 47 cases were well perform the trunk of bilateral pulmonary artery, pulmonary lobar artery, pulmonary segemental artery, pulmonary inferior segmental artery could be showed by MSCTA, MPR, MIP and VRT. 363 arterial segments were involved and 31 cases accompanied with DVT. Conclusion MSCTA in combination with CTV is of significant value in detecting pulmonary embolism accompanied with deep venous thrombo-sis.
