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.
Fluoroscopy is a type of imaging tool. It looks at moving body structures. It’s much like an X-ray "movie."
A carotid artery duplex scan is an imaging test to look at how blood flows through the carotid arteries in your neck.
Electronystagmography (ENG) is a test used to evaluate vertigo and certain other hearing and vision disorders. For this test, electrodes are placed above and below the eye. They record the electrical activity of the muscles that control eye movement.
Evoked potentials studies measure electrical activity in the brain in response to stimulation of sight, sound, or touch.
A nerve conduction velocity test measures how fast electrical impulses move through your nerves. The test is used to identify nerve damage.
An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.
A positron emission tomography (PET) scan is a type of nuclear medicine imaging test. It is used to examine various body tissues to identify certain conditions by looking at blood flow, metabolism, and oxygen use. PET scans may also be used to see how well the treatment of certain diseases is working.
Arthrography is a type of imaging test used to look at a joint, such as the shoulder, knee, or hip. It may be done if standard X-rays do not show the needed details of the joint structure and function.
Magnetic resonance imaging (MRI) uses a large magnet, radiofrequencies, and a computer to make detailed pictures of organs and structures within the body. It is used to diagnose health problems.
