positronemissiontomography

What is positron emission tomography?


Before a PET scan is carried out, a radioactive medicine is produced in a machine called a cyclotron. This is then attached to a natural chemical, such as glucose, water or ammonia, to make a radioactive version of the chemical. This is known as a radiotracer. A small amount of radiotracer is either injected into your arm, or you will breathe it in as a gas.

PET Scans

Nuclear scanning uses radioactive substances to see structures and functions inside your body. Nuclear scans involve a special camera that detects energy coming from the radioactive substance, called a tracer. Before the test, you receive the tracer, often by an injection. Although tracers are radioactive, the dosage is small. During most nuclear scanning tests, you lie still on a scanning table while the camera makes images. Most scans take 20 to 45 minutes. Nuclear scans can help doctors diagnose many conditions, including cancers, injuries and infections. They can also show how organs like your heart and lungs are working.

Positron emission tomography scan

A PET scan (positron emission tomography) is an imaging test that can help reveal how your tissues and organs are functioning. To show this chemical activity, a small amount of radioactive material must enter your body.

Lithobid

LITHOBID Tablets contain lithium carbonate, a white odorless alkaline powder with molecular formula Li2CO3 and molecular weight 73.89. Lithium is an element of the alkali metal group with atomic number 3, atomic weight 6.94 and an emission line at 671 nm on the flame photometer. LITHOBID (lithium carbonate) is indicated in the treatment of manic episodes of Bipolar Disorder. Bipolar Disorder, Manic (DSM-IV) is equivalent to Manic Depressive illness, Manic, in the older DSM-II terminology. LITHOBID is also indicated as a maintenance treatment for individuals with a diagnosis of Bipolar Disorder. Maintenance therapy reduces the frequency of manic episodes and diminishes the intensity of those episodes which may occur.

Indications
A PET scan is a complementary test. This means that it is usually used with other tests, such as X-rays or magnetic resonance imaging (MRI) scans, to diagnose or investigate a health condition. It can also be used to find out how well a treatment is working.
