MR Angiography with Three-Dimensional Time-of-Flight and Targeted Maximum-Intensity-Projection Reconstructions in the Follow-up of Intracranial Aneurysms Embolized with Guglielmi Detachable Coils

摘要

BACKGROUND AND PURPOSE: Intra-arterial contrast angiographies are generally used to confirm treatment results of endovascular neurointerventions such as aneurysm obliteration. We compared MR angiography with digital subtraction angiography (DSA) as a follow-up technique for the detection of aneurysmal remnant cavities and arterial patency in patients treated for intracranial aneurysms with Guglielmi detachable coils (GDCs).
