MR angiographic follow-up of intracranial aneurysms treated with detachable coils: Is there a need for blood-pool agents?

Ziele: In the follow-up of coiled intracranial aneurysms, blood pool contrast-enhanced magnetic resonance angiography (BPCE-MRA) using Gadofosveset trisodium (Vasovist®) was compared to 3D time-of-flight (TOF)-MRA. Methode: Thirty-two consecutive patients after coiling of 37 aneurysms were included in this retrospective study. MRAs in the steady-state phase were performed with a 1.5T scanner within eight days of digital subtraction angiography (DSA). Two experienced radiologists independently analyzed TOF sequences and Vasovist® CE-MRA images. Consensus was reached by review involving a third neuroradiologist. D…
