Magnetic resonance myelography evaluation of the lumbar spine end plates and intervertebral disks.
2005
Purpose: To evaluate the value of magnetic resonance (MR) myelography in the evaluation of intervertebral disk and end‐plate degenerative changes in the lumbar spine.Material and Methods: Conventional MR and MR myelography examinations were performed in 150 consecutive patients (69 F and 81 M, mean age 45±15 years, range 18–89). Sagittal T1 and T2‐weighted TSE images were compared to MR myelography obtained with a multishot‐TSE‐T2‐weighted sequence (4000/250/fat suppression). Coronal, sagittal, and both oblique MR myelography projections were obtained. Image analysis was carried out independently by two radiologists who categorized lumbar disks into normal, degenerated, or edematous; and ve…
Dural sac localization using myelography and its application to the lumbosacral epidural in dogs
2020
Background: The techniques described for the identification of the lumbosacral (LS) epidural space in dogs do not guarantee the needle position or an accidental subarachnoid puncture, especially in small size dogs.Aim: To determine the relationship between body weight and the location of the dural sac (DS) using myelography in dogs, and to determine the possibility of subarachnoid puncture during LS epidural based on the position of the DS.Methods: Four masked observers evaluated 70 myelographic studies of dogs, annotating the vertebrae where the DS ended, if it was localized before or after the LS space, and if accidental subarachnoid puncture during LS epidural injection was possible (yes…
Myelography: current status and post-marketing experience with iotrolan
1995
There are three imaging modalities for the diagnosis of spinal diseases: magnetic resonance imaging (MRI), computed tomography (CT) and myelography. The choice of modality is influenced by factors including diagnostic accuracy cost, radiation dose and invasiveness. For many indications, MRI has advantages over CT and myelography and is the modality of choice, and there is likely to be a trend away from myelographic examinations. In cases where myelography is indicated, it is of prime importance to reduce the frequency and severity of adverse events. During phase III and IV trials, involving over 2000 patients, general and neural tolerance of iotrolan was shown to be significantly better tha…
Stellenwert bildgebender Verfahren in der Diagnostik des lumbalen Bandscheibenvorfalles
2008
As a seeming law of nature the possibility of making use of various multiplanar sectional imaging techniques is accompanied by diagnostic exaggeration. Simple and cost effective procedures with low radiation dosage such as plain x-rays of the spine are being thrust into the background. Not seldom are patients referred to the spine surgeon with MRI or Cat scan at hand but lacking standard radiographs. As far as the assessment of intervertebral disc disease is concerned the combination of plain X-rays of the spine and computed tomography of the level in question turned out to be sufficient for indication of the operation in more than 90% of 450 patients after nucleotomie at the Orthopedic Uni…
