Comparison of image quality of subtracted and nonsubtracted breath hold VIBE and free breathing GRASP in the evaluation of renal masses.

Objective: To compare the image quality of subtracted and nonsubtracted images obtained using volumetric interpolated breath-hold exam (VIBE) and free breathing T1 weighted Golden-angle Radial Sparse Parallel (GRASP).

Methods: We retrospectively evaluated 27 consecutive patients who underwent MRI for the evaluation of renal masses. Contrast enhanced VIBE and free breathing GRASP imaging were performed, and subtraction images generated.

A Case-based Review of Abdominal (and a Few Thoracic) Emergencies and Urgencies Using Single-shot MR.

The rapid evolution of MR scanners and pulse sequence design brings an ever-expanding arsenal of diagnostic tools to radiology departments. However, this increasing abundance of diagnostic tools accentuates the challenge of using new technology efficiently and wisely-that is, to employ what may help diagnosis and/or management, but discards what has a poor likelihood of aiding patient care. This article aims to highlight practical points regarding MR pulse sequences for the evaluation of common emergencies in body imaging through case examples.
