How is meningioma diagnosed?
Diagnostic procedures for meningioma may include:
- computerized tomography scan (also called a CT or CAT scan) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. CT scans are more detailed than general x-rays.
- magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies and a computer to produce detailed images of organs and structures within the body.
- magnetic resonance spectroscopy (MRS) - a test done along with MRI that can detect the presence of particular compounds within sample tissue that can identify tissue as normal or tumor, and may be able to distinguish between different types of brain tumors. It may also be able to tell if the tumor is glial (originating in connective tissue)or neuronal (originating in a neuron, or nerve cell).
