A thorough evaluation is the first step in designing the best treatment plan. Your examination may include:

Computed Tomography   Magnetic Resonance Imaging MRI Spectroscopy MR perfusion Functional MRI Diffusion Tensor Imaging   Positron emission tomography (PET)

Computed Tomography Computed tomography (CT scan) produces a series of detailed pictures of areas inside the body taken from different angles; the pictures are created by a computer linked to an x-ray machine.

Your doctor may also ask for other tests, including:

Angiogram   Biopsy   Myelogram   Skull x-ray   Spinal tap
