Nuclear Medicine: Diagnostic Services & Targeted Treatments

Nuclear medicine is a specialized medical field that uses safe amounts of radioactive materials (radiopharmaceuticals) to diagnose, manage, and treat diseases, including cancer and heart disease. It acts as a “functional” imaging tool, revealing how organs and tissues work at a cellular level.

Key Aspects of Nuclear Medicine

• Diagnostic Imaging: Cameras are used for detecting radiation from within the body to create images of physiological processes, such as PET or SPECT scans. These can detect diseases like Alzheimer’s 5–10 years before symptoms appear.
• Therapeutic Treatment: Radioactive tracers can be directed specifically to harmful or cancerous cells, such as treating thyroid cancer or relieving bone pain.
• Radiopharmaceuticals: A radioactive material is attached to a compound (drug) that travels to a specific organ or tissue.
• Safety: The radioactive dose is very small and comparable to standard diagnostic X-rays or CT scans.

Common Uses

• Detection of cancer, its staging, and monitoring treatment.
• Assessing blood flow and heart function in cardiac diseases.
• Identifying dementia, Parkinson’s, and epilepsy.
• Evaluating thyroid function.
