Peripheral MRA Protocol should be setup with an auto move of the table after the lower leg localiser acquisition. Usually, in MRA leg protocols an auto move of 380-420 mm set by default, that means after the lower leg localiser table will automatically move …

Recent improvements in magnetic resonance imaging techniques have made magnetic resonance angiography (MRA) a very useful adjunct to invasive angiography. Fifty-five limbs in 51 patients with occlusive peripheral vascular disease were studied with …

Nov 23, 2012 · In this article, 3D MRA techniques, bolus timing issues, new IV contrast agents allowing a steady-state acquisition, principals of postprocessing, and unenhanced MRA techniques are reviewed and how to effectively use 3D gadolinium-enhanced MRA for peripheral arterial imaging is described.

The term MRA Runoff usually refers to the angiography of the lower extremities or legs. It is not uncommon for doctors to request both an MRI and an MRA of the same body part (like MRI and MRA of the brain) to get a more complete picture and more accurate diagnosis.

Jan 10, 2016 · MRAs or runoffs can be performed with 0.2–0.3 mmol/kg (0.4-0.6 mL/kg) of contrast agents that are FDA approved for multiple dosing (see contrast section). An injection rate of 1.5-2 cc/sec is suggested.

runoff vessels. The purpose of this study was to determine whether MR angiography (MRA) could aid in the detection of runoff vessels suitable for use in limb-salvage procedures and to compare the findings with those of conventional arteriography. MATERIAL AND METHODS Fifty-five lower limbs were studied in 51 patients

Recent improvements in magnetic resonance imaging techniques have made magnetic resonance angiography (MRA) a very useful adjunct to invasive angiography. Fifty-five limbs in 51 patients with occlusive peripheral vascular disease were studied with …

In order to cover the entire peripheral vasculature, at least two to three fields of view are required. Using contrast-enhanced MR angiography, the best results are obtained if the vessels of interest are imaged during passage of a bolus of contrast material.

Jun 11, 1992 · MR angiography is a noninvasive technique with greater sensitivity than conventional contrast arteriography for detecting distal runoff vessels in patients with peripheral arterial occlusive...

Nov 30, 1999 · Surprisingly, more arterial segments were seen on MRA than on contrast angiography, with these “angiographically occult” runoff vessels confirmed at surgery. Surgical plans were also changed on the basis of the additional information obtained from MRA.
