3T
MR scanners have become increasingly useful in medical imaging with their
increased SNR capabilities and potential of higher resolution images. However, with some existing pulse
sequences, mediocre lesion contrast enhancement, image artifacts, excessive vascular
enhancement, and increased signal from white matter pose challenges to the
assessment of small and subtle enhancing lesions at 3T. The purpose of this study was to compare
the quality of imaging and contrast enhancing lesion conspicuity of 3D fast
spin echo-based T1 CUBE with a T1 weighted 2D FSE and 3D volumetric
T1-weighted IR prepared 3D GRE (BRAVO) in contrast enhanced 3T brain MRI.
