representation of a slice through the body; CAT scan. PET (positron emission tomography) Scan A visual display of brain activity that detects where a radioactive form glucose goes while the brain performs a given task.

Imagine being able to detect diseases in your body‚ or being able to examine various tissues and determine its conditions. That is exactly what an positron emission tomography (PET) scan is used for. Unlike CT (computed tomography) and MRI (magnetic resonance imaging) scans‚ the PET scan can reveal the cellular level changes occurring in an organ or tissue. To obtain this information‚ a very small dose of a radioactive chemical‚ called a radiotracer‚ is injected into the vein of the patient’s arm. The

Aphasia is a language disorder that results from damage to portions of the brain that are responsible for language. For most people‚ these are parts of the left side (hemisphere) of the brain. Aphasia usually occurs suddenly‚ often as the result of a stroke or head injury‚ but it may also develop slowly‚ as in the case of a brain tumor. The disorder impairs the expression and understanding of language as well as reading and writing. "Aphasia may co-occur with speech disorders such as dysarthria or
