“…Recently a magnetic resonance myelographic technique with comparable sensitivity to conventional myelography in visualizing lumbar nerve roots was described. Magnetic resonance myelography (MRM) is non‐invasive and is superior to myelography, particularly in cases of extreme spinal stenosis 10–17 . We prospectively investigated patients with suspected herniated intervertebral discs to determine the value of MRM.…”

Magnetic resonance imaging provides a good-quality image over the entire length of the spine and can assess the morphology of the discs and cord. It is the imaging modality of choice in the investigation of spinal diseases. Magnetic resonance myelography (MRM) is non-invasive, has comparable sensitivity to conventional myelography in visualizing lumbar nerve roots and allows overall assessment of the spinal canal even in the presence of cerebrospinal fluid block. Seventy-two patients with pre-surgical diagnosis of disc herniation were prospectively investigated prior to surgery to determine the value of MRM in the diagnosis of disc herniation and spinal stenosis. The difference between the sensitivity and accuracy of MRI (89.0-95.6%, 89.1-95.7%) and MRM (82.4-89.0%, 82.6-89.1%) was not significant for both observers. There was no significant improvement with the addition of MRM to MRI (91.2-97.8%, 91.3-97.8%). Although MRM did not significantly improve the diagnostic accuracy of MRI, it allowed a better overall view of the dural sac and root sleeves, therefore making it easier to diagnose spinal stenosis and disc herniation in a minority of cases.

“…In previous reports, MR myelograms have been obtained utilizing several kinds of scanning sequences (4,9,14,15,18,19,22,24). We used sequences based on half-Fourier single-shot fast or turbo SE technique.…”

“…The heavy T2-weighting of steady-state gradientecho techniques with spin-echo sampling, such as PSIF, has created clinical applications, such as MR cisternography, to study the inner ear [127±129] or MR myelography [130,131]. Similar applications are found for the heavy T2-weighted steady-state gradient-echo techniques with FID and SE sampling, such as CISS [132,133].…”

The intention of this article is to provide an overview of all MR imaging techniques that are accessible on most of commercially available scanners and have the potential to be used in routine clinical applications. The techniques implemented by the major vendors are briefly explained, including a comparison of the commonly used acronyms. A classification scheme is introduced which provides a reasonable illustration of similarities and differences between various techniques. The imaging techniques are divided into two main groups, the spin-echo and gradient-echo sequences. Within each group is the basic sequence, those which require a preparation of the magnetization, those which use multiple echoes to fill the k-space and those which are performed in a single shot. For each technique the typical clinical applications are listed or the potential applications which have been published.
