The purpose of this study is to evaluate the therapeutic effect by FD stent on DANTE T1-SPACE imaging by comparing contrast enhanced 3D T1-weighted imaging. Patients underwent MR imaging for evaluation of pre-, post FD stent placement, and follow-up at 3T MR scanners were included. DANTE T1-SPACE of aneurysm showed dark intensity in pre-treatment study, and higher intensity in follow-up study, then darker intensity later. Enhancement ratio showed high value in pre-treatment study, and low value in follow-up study. DANTE T1-SPACE of aneurysm and enhancement ratio were negatively associated in all patients and exams.
