Nephrogenic systemic fibrosis is at present a identified, but exceptional, complication of MRI thought for being due to the injection of high doses of gadolinium-dependent distinction material in individuals with really poor kidney functionality.
Electromyelograms with nerve conduction velocity research may possibly help in confirming the multiradicular involvement of cauda equina compression. Electromyelography and nerve conduction velocity may additionally be handy in diagnosing demyelinating or inflammatory neuropathies and might be of wonderful profit in distinguishing vascular from neurogenic claudication in circumstances where by the scientific and radiographic pics are equivocal.
Cauda equina syndromes typically manifest on account of compression of your nerve roots in the lumbosacral spine distal into the conus medullaris.
