What is Nuclear Medicine?
Nuclear medicine is a specialized area of medical imaging that uses small amounts of radioactive material, called radiotracers, to diagnose and treat diseases. Unlike traditional X-rays, which provide structural images, nuclear medicine offers functional information about how your organs and tissues are working.
How Does Nuclear Medicine Work?
A radiotracer is introduced into the body, either through injection, inhalation, or swallowing. This substance accumulates in specific organs or tissues, allowing a specialized camera to detect and record the radiation emitted. A computer then processes this data to create detailed images.
Types of Nuclear Medicine Procedures
Nuclear Medicine Imaging: This involves using radiotracers to create images of organs and tissues. Common imaging procedures include:
- PET (Positron Emission Tomography) scans
- SPECT (Single Photon Emission Computed Tomography) scans
- Bone scans
- Thyroid scans
Nuclear Medicine Therapy: This involves using larger doses of radiotracers to treat certain diseases, primarily cancer. These treatments target specific cells and deliver radiation to destroy them.
When is Nuclear Medicine Used?
Nuclear medicine is used for a wide range of conditions, including:
- Cancer diagnosis and staging
- Heart disease evaluation
- Bone and joint problems
- Thyroid disorders
- Neurological conditions
Preparing for a Nuclear Medicine Procedure
Preparation for a nuclear medicine procedure varies depending on the specific exam. Your health care provider will give you detailed instructions. You may have dietary restrictions or avoid certain medications before the procedure.
The Nuclear Medicine Procedure
The procedure itself is typically painless and involves administering the radiotracer. You may be asked to lie still during the imaging process. The time required for the procedure varies depending on the type of exam.
After the Nuclear Medicine Procedure
After the procedure, you can usually resume your normal activities. The amount of radiation used in nuclear medicine is low, and the radiotracer is quickly eliminated from the body. However, it's essential to follow your health care provider's instructions regarding any post-procedure care.
