PDFAbstract
Objective Evaluated 3D dynamic contrast-enhanced magnetic resonance angiography (3D CE-MRA) diagnosis accuracy and application of arteriosclerotic obliterans (ASO) of the lower limbs. Methods Adopted by the 3D CE-MRA and DSA, the two different image diagnosis methods,the image results of ASO were compa-ratively studied. Results Compared with the results of DSA. Lower limb artery stenosis valuation of 3D CE-MR coincide rate was 90.5%. For lower limb artery lesions diagnostic, the sensitivity, specificity, accuracy, positive pre-dictive value, and negtive predictive value of 3D CE-MRA were 98.17%, 95.05%, 96.67%, 95.54%, and 97.96%,respectively. Conclusion The compared results show that: DSA lower limb artery stenosis diagnosis was "gold standard", but it was invasive, risk and cost. Not suitable for a Lower limb artery stenosis diagnostic first choice method. The 3D CE-MRA has unique advantages on exploring vascular lesions in lower limbs. It was also noninvasive, no radiation and simple that will become the main testing methods for ASO.
