A variety of diagnostic tests are available to help clinicians determine the extent of nerve, muscle or circulatory system impairment in patients who have neurological conditions. The tests in the following list are among those most commonly performed to assess Parkview Neuroscience patients.
Computer tomography scan (CT, or CAT, scan)
A computer compiles multiple X-rays from the scanner to produce an image that gives detail of the area being scanned, such as the brain or spine.
Magnetic resonance imaging (MRI)
Unlike CT, the MRI uses magnetic fields and radio waves to make a three-dimensional image of the brain or spine.
Magnetic resonance angiography (MRA)
Using the same technology as MRI, the MRA provides images of major arteries and their branches in the head and neck.
Electromyogram and nerve conduction studies (EMG/NCS)
Electrical impulses along nerve roots, peripheral nerves and muscle tissue are measured in this test indicating nerve damage, nerve healing or other sites of nerve compression.
Myelogram
After an injection of dye into the spinal column, X-rays are taken to identify locations of pressure on the spinal cord or nerve roots.
