Recognition of Brain Metastases Using Gadolinium-Enhanced SWI MRI: Proof-of-Concept Study.

SWI MRI, a T2-dominant MRI sequence with T1 effect, uses intrinsic structural susceptibility to create enhancement among brain structures. We evaluated whether gadolinium-enhanced SWI (SWI-Gd) improves brain metastasis detection in combination with other MRI sequences. MRI images of 24 patients (46 studies) were prospectively acquired using a 1.
