A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.

Endovascular coiling is used to block blood flow to an aneurysm.

A CT scan is a type of imaging test. It uses X-rays and computer technology to make images of the body. A CT scan can make detailed pictures of any part of the body, including the bones, muscles, fat, organs, and blood vessels. They are more detailed than regular X-rays.

X-rays use invisible electromagnetic energy beams to make images of internal tissues, bones, and organs on film. Standard X-rays are done for many reasons, including diagnosing tumors or bone injuries.

Computed tomography is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs.

Magnetic resonance imaging (MRI) uses a large magnet, radiofrequencies, and a computer to make detailed images of organs and structures within the body, in this case, the brain and spine. MRI is used to help diagnose a health problem.

An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.

A carotid artery duplex scan is an imaging test to look at how blood flows through the carotid arteries in your neck.

A bone density test is used to measure the bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.
