Neurodiagnostic Tests

Neurodiagnostic Tests :

CT Scan :
Computerized tomography (CT scan) uses x-ray technology to produce multiple cross-section images. In addition to providing images of the brain and nervous system, they can be used to identify broken bones, tumors, blood clots, heart disease, and internal bleeding.

MRI Scan :
Magnetic resonance imaging (MRI scan) uses a powerful magnet combined with radio waves to examine organs, soft tissues, and skeletal structures. MRI scans are especially valuable in finding brain and spinal cord abnormalities. They may also be used to help diagnose torn ligaments, tumors, circulation (blood flow) problems, inflammation (e.g., arthritis), and infection.

PET Scan :
Positron emission tomography (PET scan or PET imagery) uses radiation from the emission of positrons (extremely small particles discharged from a radioactive substance) to create images that can help detect and evaluate cancer and the effects of cancer therapy. This test also can be used to diagnose a variety of neurological conditions, including memory disorders, tumors, and seizure disorders.

In a PET scan, a small amount of a radioactive substance is combined with a natural body compound (e.g., glucose, water, or ammonia) and is injected into the patient. Once the substance has had time to circulate through the body and accumulate in the tissues (generally 30 to 90 minutes), a PET scanner is used to detect the various levels of energy given off by the positrons and produce images. Different colors or levels of brightness indicate different levels of organ and tissue function. Cancer tissue, for example, uses more glucose than normal tissue and shows up brighter on the PET scan.
