(1) Objective : To evaluate CT and CT myelography ( CTM ) in diagnosis of lumbar disc herniation.

(2) Computer-assisted myelography indicated that the metal wire remained in place and that the syrinx had collapsed.

(3) Magnetic Resonance Imaging and Magnetic Resonance Myelography in the Presurgical Diagnosis of Lumbar Foraminal Stenosis.

(4) Methods: Myelography and CTM scanning were performed in 200 patients with surgically proved intervertebral disc hernia.

(5) The experience of myelography , CT plain film scanning and CTM in the diagnosis of 52 patients with prolapse of lumbar intervertebral dis were retrospectively analyzed and compared.

(6) Conclusion CTM is more accurate than myelography in the diagnosis of lumbar disk heriniation.

(7) Objective To assess the value of myelography and CTM for the diagnosis of lumbar disc herniation.

(8) Results: Based on the operativc findings the accurate rate was 87.5 % in myelography and 96? 9 % in CTM.

(9) Objective To re - evaluate upright flexion - extension myelography and computed tomographic myelography in diagnosing lumbar spinal stenosis.
