Gadolinium Magnetic Angioresonance in the Study of Aortoiliac Disease

Abstract

There is a need for noninvasive methods for the early identification of patients with intermittent claudication who need surgical treatment. Newer magnetic resonance angiography (MRA) techniques allow detailed study of the arterial tree with image quality similar to that of conventional arteriography. From April 1997 to January 2001, 30 patients with intermittent claudication of the lower limbs were studied with both imaging methods. In each case, the MRA images were examined first and the arteriographic images were examined 15 days later. Examiners interpreting the arteriographic images were blinded to the results of the corresponding MRA images. After each examination (MRA and arteriography), a vascular surgeon suggested a surgical plan. MRA showed results similar to those of arteriography, although with inferior image quality. No patient had an allergic reaction or side effects due to administration of contrast material. There was total agreement between MRA and arteriography in regard to the morphologic analysis and proposed surgical plans in every case. In conclusion, MRA is a feasible, useful, and less invasive alternative for the morphologic evaluation of the aortofemoral area in patients with intermittent claudication of lower limbs.

“…MRA has been recommended as an alternative to the more invasive option of angiography in the assessment of patients with aorto-iliac disease (29,30). Sueyoshi et al (30) found that MRA has a sensitivity of 97% and specificity of 99.2% for aorto-iliac and lower extremity arteries.…”

Comparison of Ultrasonography, Computed Tomography and Magnetic Resonance Imaging With Intraoperative Measurements in the Evaluation of Abdominal Aortic Aneurysms

“…Nuclear magnetic angioresonance (NMR) ( Figure 6) is a recently developed technique that utilizes a powerful magnetic field and the different tissue characteristics to generate images in multiple planes. 3,18,19 Developed at the end of the 1980s, it is relatively noninvasive and provides infor- mation about the arterial wall morphology, the adjacent structures, and the physiology of arterial flow. It does not result in adverse effects from radiation, radio-opaque contrasts, or arterial catheterization punctures that can be caused by other imaging techniques.…”

Natural history of stenosis in the iliac arteries in patients with intermittent claudication undergoing clinical treatment

“…Although it is still not very precise for quantifying stenosis, 27,28 it offers security in the diagnosis of complete occlusions, which is the reason why this method was chosen. 29 Both duplex scans and MRA were used in this study because MRA can only be used to determine whether the vessel is occluded, and not to measure the degree of occlusion.…”
