Rubidium-82 chloride

Rubidium-82 chloride is a radiopharmaceutical agent used in Positron Emission Tomography (PET) imaging of the heart. It is a radioactive form of the element rubidium and is used to evaluate the blood flow in the heart.

Uses

Rubidium-82 chloride is used in medical imaging to help visualize and measure the blood flow in the heart. This is particularly useful in diagnosing and monitoring conditions such as coronary artery disease.

Mechanism of Action

Rubidium-82 chloride works by emitting positrons that can be detected by a PET scanner. When injected into the body, it travels to the heart, where it is taken up by the heart muscle cells. The positrons it emits interact with electrons in the body, producing gamma rays that can be detected and used to create images of the heart.

Side Effects

As with any radiopharmaceutical, there are potential side effects associated with the use of Rubidium-82 chloride. These can include allergic reactions, changes in heart rhythm, and exposure to radiation.

Precautions

Before using Rubidium-82 chloride, it is important to discuss any existing health conditions or medications with your doctor. Pregnant or breastfeeding women should not use this medication due to the risk of radiation exposure to the fetus or infant.
