- W2385946030 abstract "Objective To evaluate the clinical application of 3D dynamic contrast enhanced MR angiography (3D DCEMRA) with the techniques of total image matrix (Tim) in diagnosing lower extremity (femoropopliteal and infrapopliteal) artery stenosis, and compared with DSA as the golden standard. Materials and Methods 3D DCE MRA was performed in 41 cases suspected of lower extremity stenosis with the techniques of Tim coil, multireceiving channels and integrated parallel acquisition techniques (iPAT), automatic bed moving and nongap composing. The delay time was determined by Test bolus. 3D MIP reconstruction was used in the post processing. All cases were proved by IADSA in one week after 3D DCE MRA examination. Moderate stenosis (luminal narrowing≤50%), significant stenosis (luminal narrowing 51%～99%) and occlusion(luminal narrowing of 100%) were identified on 3D DCE MRA. The sensitivity and specificity of significant stenosis and occlusion were calculated. Results Good image quality was 95.1%. Compared with IADSA, the sensitivity, specificity and accuracy of 3D DCE MRA in diagnosing significant stenosis and occlusion (≥50% stenosis) of femoropopliteal arteries were 91.1%, 92.9% and 92.3%, respectively. The sensitivity, specificity and accuracy in diagnosing significant stenosis and occlusion (≥50% stenosis) of infrapopliteal arteries were 82.2%, 75.4% and 83.9%, respectively. Conclusion 3D DCE MRA with the techniques of Tim coil, multireceiving channels and iPAT techniques is a noninvasive, safe, accurate and practical method of diagnosing lower extremity artery diseases, which is more reliable in diagnosing stenosis of femoropopliteal arteries, but its resolution rate of smaller vessels (such as foot arteries) should be further improved." @default.
