BACKGROUND AND PURPOSE:
This retrospective study evaluated the utility of contrast-enhanced T1-weighted 3D fast spin-echo–based sampling perfection with application-optimized contrasts by using different flip angle evolutions (SPACE) sequences for brain metastasis detection on 3T MRI compared with a gradient-recalled echo–based 3D FLASH sequence.
MATERIALS AND METHODS:
We identified all patients at a single institution who underwent SPACE and 3D FLASH sequences as part of a practice…
