OBJECTIVE: We examined the usefulness of imaging portosystemic collaterals accompanying @entity1575 by magnetic resonance angiography (MRA), which facilitates imaging of the vascular system without contrast medium. METHODS: MRA was performed in 30 @entity1 with @entity1575 . Of the 30 @entity1 , percutaneous transhepatic portography (PTP) was performed in 10 @entity1 , and @entity432 ( @entity432 ) was performed in 20 @entity1 . The three-dimensional (3D) phase contrast method was used for MRA. Study 1: The ability to image portosystemic collaterals was compared between PTP or @entity432 and MRA. Study 2: The usefulness of MRA for evaluating the effect of treatment on gastric and @entity2312 was examined. RESULTS: Study 1: In comparing PTP and MRA (n = 10), the left gastric vein (n = 10), splenorenal (gastrorenal) shunt (n = 5), and paraumbilical vein (n = 2) were imaged similarly. However, MRA did not reveal any @entity2312 (n = 10). In comparing @entity432 and MRA (n = 20), the left gastric vein (n = 17), splenorenal (gastrorenal) shunt (n = 10), and paraumbilical vein (n = 4) were imaged similarly. Whereas @entity432 revealed @entity2312 (n = 4) in four @entity1 , MRA revealed @entity2312 in only one @entity1 . Study 2: When the effect of treatment for varices was evaluated, MRA 3 wk after embolization therapy for @entity2312 (n = 4) confirmed the disappearance of gastrorenal shunt. However, it was impossible to evaluate @entity2312 by MRA. CONCLUSIONS: It was possible to image portosystemic collaterals accompanying @entity1575 by MRA. MRA was useful as a routine examination. Furthermore, it was useful for evaluating the effect of embolization therapy on @entity2312 .
