Angiomagnetic resonance imaging of iliofemorocaval XXXX .

@entity1150 @entity1 @entity49 @entity715
Although magnetic resonance imaging has been proposed for the diagnosis of @entity1150 ( @entity1150 ), its role in diagnostic strategy remains to be defined. We compared prospectively magnetic resonance angiography (MRA) with two-dimensional time-of-flight with contrast venography (CV) and colour duplex sonography (CDS) in 25 @entity1 with @entity1150 of the pelvis confirmed by CV. All @entity1 were examined by CV (gold standard) and MRA and 17 by CDS. These studies were compared for @entity1150 diagnosis in the pelvis and inferior vena cava and analysis of @entity715 spread. MRA was positive in 25 @entity1 whose @entity1150 was diagnosed by CV (100% sensitivity). MRA sensitivity and negative predictive value were 100%, specificity 98.5% and positive predictive value 97.5% for the diagnosis of @entity715 at each anatomic level. There were discrepancies between MRA and CV (2 false-positive results for 2 venous segments) and between CDS and CV (2 false-positive and 3 false-negative results). CV was uninterpretable for 8.8% of segments and CDS was often technically limited to the pelvic level, whereas all venous segments explored were analysable in MRA. MRA gave excellent results for positive diagnosis and @entity1150 spread. MRA is a potentially valuable technique for assessing iliofemorocaval @entity49 .
