Die Kernspintomographie der Wirbelsäule und des Rückenmarks im Vergleich zu Computertomographie und Myelographie

Abstract

In cases of syringomyelia MR is superior to CT and myelography in visualisation and delineation of the extent of the process. In diagnosing spinal tumours MR is a more sensitive method than CT and myelography. MR provides additional information on sagittal and frontal planes regarding the extent of the tumour. In diagnosis of disc prolapse MR seems to be as accurate as CT or myelography. We obtained additional information in diagnosis of degenerated disc tissue. Spinal stenosis is easily recognisable. CT was superior in differentiation of bony and disc protrusion. The results show that MR has opened up new possibilities in the diagnosis of spinal diseases and will result in a reorientation of the diagnostic approach.

The myelon in cervical spinal canal stenosis: Imaging by X-ray and MRI

“…-the reproducibility in repeat investigations, and -the imaging mainly in proton-mixed images and T2-weighted sequences. Other study groups report such findings [2]. The elevation of CSF protein found in most cases suggests a tissue reaction.…”

“…However, the normal surgical biopsies gave evidence against extensive demyelinations, whereas small lesions of individual fibers would hardly have been detected by the resolution capacity of MRI. Obstruction or congestion of large vessels with manifest infarcts or gliosis [2,3,7] appear to be relatively implausible for the same reasons. Findings relating to biomechanical factors [1] appear to be important.…”

Emergency Magnetic Resonance Examination of Patients with Spinal Cord Symptoms

“…The extent of an intramedullary tumour can be precisely defined because its signal intensity differs from that of the cord (3,4,12). It may, however, as we found, be difficult to differentiate between an intramedullary protein-containing cystic tumour and a solid tumour because the signal characteristics are very similar (6).…”

Transösophageale Echoskopie des Spinalkanals*

“…Mit dem Einbau mechanischer oder Phased-array-Schallköpfe in ein handelsübliches Gastroskop hat die endoskopische Ultraschall-Diagnostik in der Gastroenterologie und Kardiologie in den letzten zehn Jahren einen hohen Stellenwert erlangt (1,(4)(5)(6)9,11,12). (2,3,8,13).…”
