PDFAbstract
Objective To evaluate the study value of multi-slices helical CT angiography and three dimensional dynamic contrast-enhanced MRA in lower extremities arteriosclerotic occlusion disease(ASO). Methods 38 cases of ASO were performed with MS CTA and 3D CE-MRA between two weeks. The CT original axial data was reconstructed by ADW4.6 workstation of MPR, MIP and VR, compared with processed MIP images with MRI. Bilateral lower extremity arterial vascular system of each case was divided into three regions and 23 segments, each segment was evaluated for the presence and degree of vascular stenosis. Results All the 38 cases including 8 cases with mild stenosis, 14 cases with moderate syenosis, 12 cases with significant stenosis and 4 cases with occlusion. The significant disease of the lower extremities were demonstrated clearly by MS CTA and 3D CE-MRA. Conclusion MS CTA and 3D CE-MRA are excellent in patients with clinical symptoms of the arteriosclerotic occlusive disease of lower extremity, which can provide more accurate informations for clinical diagnosis and treatment.
