Magnetic Resonance Neurography provides high-resolution images to demonstrate entrapment of the nerve and morphological changes in the nerve (8).
Sciatica of nondisc origin and piriformis syndrome: diagnosis by magnetic resonance neurography and interventional magnetic resonance imaging with outcome study of resulting treatment.
22,43,46) It is also important in identifying the level of nerve injury, (47) for use during surgical repair using nerve grafts, (48-51) performing nerve blocks, (52) neurography, (30) and for the modeling of neuromuscular compartments.
Magnetic resonance neurography sUidies of the median nerve before and after carpal tunnel decompression.
allows scans of the nerves outside the spinal cord, such as the sciatic nerve, which only one other scanner in the country can do at present.
Special imaging for nerves with magnetic resonance neurography
can detect piriformis muscle syndrome--a condition in which the narrow piriformis muscle irritates or pinches the sciatic nerve.
Unlike conventional MRI scans, magnetic resonance neurography can reliably image nerves.
To find out whether MR neurography could effectively identify the cause of sciatica, researchers at Cedars-Sinai Medical Center in Los Angeles evaluated patients whose symptoms had not improved after diagnosis or treatment for a herniated or damaged disc.
Such terms expand the lexicon we have already developed in the field, terms such as Freud's pathography, Luria's neurography
, Kathryn Hunter's clinical biography, James Hillman's case fiction, and Oliver Sacks's clinical tales.
Filler and his colleagues at the University of Washington in Seattle first demonstrated the technique, called magnetic resonance neurography, 3 years ago (SN: 3/20/93, p.
An existing MRI machine could be modified to perform neurography at a cost of $80,000 to $400,000-10 to 20 percent of the machine's original price, Filler says.
