Objective    To assess the clinical value of multi-slice CT angiography (MSCTA) in the arteriosclerotic occlusive disease of lower limb.     Methods    Forty-eight patients

clinically suspected as the arteriosclerotic occlusive disease of lower limb

underwent MSCTA，DSA and/or surgical therapy. All reconstructed images were reformed by means of MIP

VR

MPR and CTVE.     Results    Forty-eight patients were diagnosed correctly by MSCTA

  with the sensitivity

specificity and accurate rate of 100％

compared with DSA and/or surgical therapy． The percentage of  stenosis area was measured from the multiplanar reconstruction (MPR) images of MSCTA， including 3 mild  stenosisin

8 moderate stenosis

15 severe stenosis and 21 occlusion. Plaques and endoscopic views of  stenosis were delineated in MSCTA and CTVE.     Conclusion    MSCTA as an accurate method for the assessment of  stenosis and plaques of arteriosclerotic occlusive disease of lower limb is useful for preoperative evaluation.
