Abstract

We demonstrate that whole‐body, single‐shot imaging is practical for imaging out of the central plane, including oblique axes. The technique is illustrated by images of the heart in the cardiac long‐ and short‐axis and by coronal images of the brain. Secondary gradients can produce additional image distortion and ghosting in these images. These artifacts are a direct consequence, predictable by Maxwell's equations, of the large gradients used in echo planar imaging. We show that these effects are, in general, made smaller by working at a high magnetic field.

Proton magnetic resonance (MR) body images of the normal, adult human which have total scan times of typically only 40 ms per image are presented. There is no loss of spatial or contrast resolution due to motional blumng or ghosting; rather, movie loops of multiple 40-ms images directly demonstrate

## Abstract The objective of this study was to investigate the feasibility of whole‐body imaging at 7T. To achieve this objective, new technology and methods were developed. Radio frequency (RF) field distribution and specific absorption rate (SAR) were first explored through numerical modeling. A

MR oximetry requires a T2 measurement that is accurate within 5% in vivo. Simple methods are susceptible to signal loss and tend to underestimate T2. Current methods utilize RF pulses or RF cycling patterns that prevent signal loss at each data acquisition. However, using these methods with imperfec
