The aim of this study was to investigate whether time-of-flight (TOF) magnetic resonance (MR) angiography with 7 Tesla MR scanner can display the anterior choroidal artery (AchA) in patients with sella and parasella tumors. 7T-MRA demonstrated at least one AchA in all seven patients. In two of 3 patients who underwent microsurgery through craniotomy, although two AchAs were intraoperatively identified, 7T-MRA displayed only one AchA.
