Disk processes in MR.

Disk processes can be differentiated in MR with the introduction of high resolution coils and the use of a multi slice technique with a minimal slice thickness of 5 mm. By using a sensitive double echo sequence we found that in the 80 patients examined the size and extent of the posterior herniation could be well demonstrated. Sagittal slices show the relationship of the herniation to the spinal cord. The pathomechanical parts of a disk process such as ruptured or preserved anulus fibrosus, perforated or intact posterior longitudinal ligament can be differentiated. For lateral lying processes in connection with the foramen intervertebral and the spinal roots an axial slice parallel to the intervertebral space is recommended. All CT findings especially in the cervical spine region were shown and further qualified.

[MR imaging of the cervical spine using special coils].

The signal/noise ratio of MR images can be improved for organs near the surface by means of special coils. It is shown for neck imaging that a close-fitting saddle-shaped coil is more suitable for application between C 2 and Th 1, than a saddle coil for the entire head or a disc-shaped coil. Such a close-fitting saddle-shaped coil is an essential prerequisite for effective neuroradiological diagnoses of the spinal cord with nerve roots, of the spinal column, and of the vessels of the neck.
