Magnetic resonance angiography. (A) Contrast-enhanced (CE) magnetic resonance angiography (MRA) sequence showing recanalisation of a previously coiled basilar tip aneurysm (large white arrow). (B) Time-of-flight MRA sequence revealing the refilling of the same basilar tip aneurysm (small white arrow). (C) CE-MRA and (D) time-of-flight MRA sequences after retreatment. No additional filling of the aneurysm is seen (red arrows).
