Surface-coil MR imaging of orbital neoplasms.
Fifteen patients with orbital neoplasms demonstrated by CT were studied with magnetic resonance (MR) using a 13 cm surface coil and a 0.6 T superconducting magnet. The use of a surface coil allowed for a reduction in slice thickness and a significant improvement in spatial resolution resulting in better demonstration and improved characterization of orbital lesions. All neoplasms (15/15) were d...
متن کاملRheumatoid arthritis of the cervical spine: surface-coil MR imaging.
Fifteen patients with classic rheumatoid arthritis were investigated with plain films, pluridirectional tomography, and surface-coil T1-weighted MR imaging at 500/17 (TR/TE). We evaluated the atlantodental interval; basion-dental interval; density or intensity of the dens; dens erosion; cranial settling; anterior, posterior, lateral, or rotatory atlantoaxial subluxation; subaxial subluxation; l...
متن کاملThe cervical nerves and foramina: local-coil MR imaging.
A detailed study of the magnetic resonance (MR) appearance of the cervical nerves and neural foramina is presented. Using a "butterfly" local coil and a 1.5-T GE Signa MR system, the authors obtained 3-mm-thick axial, parasagittal, and 45 degrees oblique MR images of the cervical neural foramina in four normal volunteers. For the oblique images, subjects were rotated 45 degrees toward the right...

متن کاملA flexible mercury-filled surface coil for MR imaging.
The use of surface coils in MR imaging allows for the possibility of obtaining images with increased signal-to-noise ratio and increased spatial resolution [1]. To obtain the maximum signal, the coil should be placed close to the region to be imaged. For rigid coils , a close fit may be difficult to obtain routinely and can lead to patient discomfort. We describe a technique for constructing fl...
