Unenhanced 3D turbo spin-echo MR angiography of lower limbs in peripheral arterial disease: a comparative study with gadolinium-enhanced MR angiography.

Objective: The purpose of this study was to assess the feasibility and diagnostic performance of an unenhanced MR angiography sequence (Syngo Native Space, Siemens Healthcare) to detect and quantify lower-limb peripheral arterial disease (PAD), with gadolinium-enhanced MR angiography (CE-MRA) as the reference standard.

Subjects And Methods: Fifty-one patients known to have lower-limb arteriopathy were included in this prospective study. For every patient, we performed Native sequence and CE-MRA on a 1.
