title: Total body MR angiography and atherosclerosis.
abstract: The early detection of atherosclerotic vascular lesions is very important for diagnostic and interventional purposes. Traditionally, Digital Subtraction Angiography (DSA) is considered the reference diagnostic technique, but recently several new non-invasive procedures have been developed, like Doppler US, CT-angiography and MR-Angiography (MRA). MRA has progressively gained acceptance as a valid alternative. At present, the use of fast sequence and contrast injection allows to acquire segmental volumes within a few seconds (10-20s), with high diagnostic quality and accuracy. The systemic distribution of atherosclerosis requires the use of techniques which can assess the arterial system as exhaustively as possible. A MRA scanning protocol including all arteries from the epiaortic branches to the calf has recently been proposed with encouraging preliminary results. In this article, the relevant technical concepts in MRA and the present most important clinical findings are reported and discussed, including the proposed technique for a whole-body MR angiographic assessment of the atherosclerotic patient.
