“…MR is considered to be ideal for the evaluation of patients with myelopathy (9,12) whereas CT myelography has been found to be more accurate in patients with radiculopathy (10,13). However, in a recent report, MR imaging, including gradient echo images, was suggested as the procedure of choice for the evaluation of suspected cervical radiculopathy (7).…”

“…Magnetic resonance (MR) imaging is being used with increasing frequency to examine these patients. Surface coil MR has proven to be equivalent or superior to myelography in cases of cervical myelopathy (12) whereas the role of MR in the evaluation of patients with radiculopathy is more controversial (2,7,9,10,13). The present prospective study was undertaken to elucidate whether MR can replace myelography and CT myelography in the preoperative evaluation of patients with radiculopathy and/or myelopathy caused by cervical spondylosis or disk herniation.…”

Twenty-six patients with cervical radiculopathy and/or myelopathy caused by spondylosis or disk herniation were examined with myelography, CT myelography and MR. Fourteen of the patients were operated upon and II of them underwent postoperative MR and CT. The three radiologic methods provided comparable information about narrowing of the subarachnoid space and compression of the spinal cord. It was more difficult to distinguish bone from soft tissue with MR only, but the combination of MR and conventional radiography gave sufficient information for this differentiation. When radiologic nerve root sheath deformity was compared with clinical radiculopathy, myelography, CT myelography and MR had similar sensitivity and accuracy. Postoperative MR could reveal remaining indentation on the thecal sac and the cord but CT without contrast medium was useful as a complement to determine the aetiology of the indentation. Because MR has several practical advantages, it is well suited as the primary imaging modality, together with conventional radiography, for the preoperative radiologic evaluation of patients with cervical radiculopathy and/or myelopathy. Postoperative MR is useful in patients with persistent or new symptoms.

“…These findings have been used as such in numerous other studies. 6,7 With continued improvement in imaging, the depiction of a patient's anatomy is becoming clearer and more accurate and is approaching equivalence to looking at it. Surgical cases were from the clinical practice of 3 attending orthopedic spine surgeons from a single institution.…”

“…10 Gradient-recalled echo (GRE), or gradient-echo, sequences allow for delineation of bone and disk margins, provide excellent contrast between the spinal cord and surrounding subarachnoid space, and allow clear visualization of the neural foramina and exiting nerve roots. Gradient-echo axial images are used in the cervical and thoracic spine to detect spinal canal and foraminal stenoses 11 and serve as an important complement to long repetition time spin-echo imaging, given faster acquisition time of GRE. As a result, GRE images are less susceptible to patient motion artifact.…”
