Evaluation of intracranial aneurysm: Comparison between ZTE-MRA and 3D-TOF-MRA

The high incidence of intracranial aneurysms and the high mortality rate after rupture highlight the requirement and importance for early and accurate visualization of the aneurysm profile for subsequent patient treatment. Here we report a patient with an intracranial aneurysm who underwent digital subtraction angiography (DSA), zero echo time MRA (ZTE-MRA), and three-dimensional time-of-flight MRA (3D-TOF-MRA) on admission and after operation. The imaging quality and accuracies of ZTE-MRA and 3D-TOF-MRA were compared with DSA, the gold standard, in pre-operative and post-operative evaluation of intracranial aneurysms. Comparison of the two MRAs, ZTE-MRA has greater advantages in imaging.
