Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray ...
Lumbar provocative discography (also referred to as "discography" or discogram) is an invasive diagnostic procedure for evaluation for intervertebral disc pathology. It is usually reserved for persons with persistent, severe low back pain (LBP) who have abnormal spaces between vertebrae on magnetic resonance imaging (MRI), where other diagnostic tests have failed to reveal clear confirmation ...
The radiologist will first numb the skin with the local anesthetic and then inject the gadolinium based contrast media into the spinal cord at the interspace between third and fourth lumbar vertebrae (L3-L4). Then the patient will be asked to roll on the table until the contrast is evenly distributed in the spinal cord and fill the nerve roots.

Quantitative CT scans are primarily used to evaluate bone mineral density at the lumbar spine and hip. In general, solid phantoms placed in a pad under the patient during CT image acquisition are used for calibration. These phantoms contain materials that represent a number of different equivalent bone mineral densities.
X-ray, MRI Facet syndrome is a syndrome in which the facet joints ( synovial diarthroses ) cause painful symptoms. [ 1 ] In conjunction with degenerative disc disease , a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain.
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel Prize .
