Getting More Out of Follow-up Three-Dimensional Time-of-Flight Magnetic Resonance Angiography in Endovascularly Treated Intracranial Aneurysms.

Background: We retrospectively re-evaluated follow-up three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) in patients with aneurysms treated with coiling at our Institute.

Aims: To document the type and frequency of postcoiling residue patterns as seen on follow-up MRA and to document their evolution with time where a further follow-up MRA was available. To assess the implications of the location of the aneurysm on residue and recurrence.
