BACKGROUND AND PURPOSE: To compare the utility of contrast-enhanced MR Angiography (CE-MRA) with digital subtraction angiography (DSA) after endovascular treatment of @entity438 with Guglielmi detachable coils. METHODS: From April 1999 to August 2002, 106 @entity1 with 107 @entity439 treated by endovascular coiling using Guglielmi detachable coils underwent simultaneous DSA and CE-MRA at follow-up (mean: 12.9 range: 5 to 27 months). DSA was performed as the standard reference. MR angiographic images were analyzed independently by 2 senior radiologists (J.-Y.G., S.C.) and DSA by a third radiologist (X.L.). Findings were assigned to 1 of 3 categories: complete obliteration (class 1), residual neck (class 2) and residual @entity439 (class 3). RESULTS: DSA at follow-up demonstrated 65 (60.6%) complete obliterations (group 1), 21 (19.7%) residual necks (group 2) and 21 (19.7%) residual @entity439 (group 3). One @entity1 (0.9%) experienced @entity439 rebleed during the follow-up period. Among 101 assessable imaging comparisons, interobserver agreement was determined to be very good for CE-MRA (kappa=0.96) with only 4 discrepancies between both examiners. Comparison between CE-MRA and DSA showed an excellent agreement between techniques (kappa=0.93). Of the 21 with residual necks described on DSA, 20 were seen on CE-MRA. CE-MRA detected all 19 residual @entity439 . CONCLUSIONS: CE-MRA after selective embolization of @entity438 is useful and comparable to DSA in the assessment of aneurysmal recanalization either as residual neck or aneurysmal sac.
