The value of upright standing myelography in the diagnosis of lumbar disc herniation / 介入放射学杂志

ABSTRACT

Objective To evaluate the value of upright standing myelography in the diagnosis of lumbar disc herniation (LDH). Methods One hundred and ninety six patients with LDH diagnosed by CT or MRI were examined by upright standing myelography before surgery. Results The most diagnosis of myelography were accorded with CT or MRI, but 7 patients of myelography with LDH at L4-5 showed compression of nerve roots, while the images of these on CT or MRI only showed disc bulge or protrusion without nerve root compression. Conclusions Myelography in the upright standing position is perhaps superior to CT or MRI for the diagnosis of LDH, especially LDH at L4-5 with nerve root compression.
