Conventional x-ray angiography has traditionally played a prominent role in
the radiologic evaluation of large vessel vasculitis. Recently, noninvasiv
e magnetic resonance (MR) methods have received much attention for their po
tential to complement and possibly supplant conventional angiography. In pa
rticular, promising advances have been made in the areas of MR angiography
and physiologic imaging. MR provides high resolution anatomic information,
including lumen configuration and vascular wall thickness, and physiologic
data, such as measurements of the degree of wall enhancement and the presen
ce of edema. Moreover, imaging data are obtained noninvasively in a multitu
de of obliquities. Owing to these features, MR occupies a unique role in th
e evaluation of large vessel vasculitis. Curr Opin Rheumatol 2001, 13:47-47
