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.</span></span></span> <span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">Comparison of the two MRAs, ZTE-MRA has greater advantages in imaging.</span></span></span></span></span></span></span></span></span></div> <span style="font-size:10pt"><span style="line-height:119%"><span style="font-family:Calibri"><span style="color:black">&nbsp;</span></span></span></span><br> &nbsp; Intracranial aneurysm, zero echo time, magnetic resonance angiography, spin labeling, time leap. 723 725 http://ijrr.com/browse.php?a_code=A-10-1-970&slc_lang=en&sid=1 J.
