β¦ Synopsis
A modified version of a single-turn solenoid with rectangular symmetry, which we call a ribbonator, provides excellent magnetic resonance images of the hand and wrist when used as both the transmitter and the receiver in a 1.5-T clinical imaging system. The very high RF efficiency provides excellent signal-to-noise and anatomical resolution. Design equations and RF properties of the resonator are discussed. o 1989 Academic Press, Inc.

## Abstract This study represents a new attempt to nonβinvasively analyze threeβdimensional motions of the wrist in vivo. A volumeβbased registration method using magnetic resonance imaging (MRI) was developed to avoid radiation exposure. The primary aim was to evaluate the accuracy of volumeβbased
Many modern medical diagnostic techniques, including magnetic reso- ( ) nance imaging MRI and computed tomography, are based on image reconstruction from projections. Unfortunately, the high cost of acquiring, maintaining, and operating MRI equipment makes it unavailable for hands-on undergraduate s
Next, the manuscripts underwent review by the editorial board of JMRI. This scientific symposium was designed to describe and review current methods of quantitative cerebral perfusion imaging in the human brain using MRI, to evaluate different methods, to describe new developments, and to assess cl
The advent of magnetic resonance imaging (MRI) prompted the reevaluation of the incidence of popliteal cyst and its associated injuries. We reviewed more than 1000 consecutive MRI examinations of the knee performed on patients referred for evaluation of internal derangement. We report a 5% incidence
