What Is a Full Body PET Scan?
A full-body PET (Positron Emission Tomography) scan is an advanced imaging test that helps detect diseases, monitor organ function, and assess treatment effectiveness. It uses a small amount of radioactive tracer, which is injected into the body and absorbed by tissues and organs. The scanner then captures detailed images of how the body’s cells are functioning, providing valuable insights that other imaging techniques, like CT or MRI, may not detect.
PET scans are commonly used to detect cancer, evaluate brain disorders, and assess heart conditions. They can identify abnormalities at the cellular level, allowing for early diagnosis and targeted treatment planning. The procedure is non-invasive and generally painless, with patients needing to lie still while the scanner captures images.
To prepare for a full-body PET scan, patients may be advised to avoid eating a few hours before the test and limit physical activity. The scan typically takes about an hour, and results help doctors determine the best course of action for treatment. Regular follow-ups with a healthcare provider ensure accurate interpretation of findings. PET scans play a crucial role in modern medicine by offering detailed diagnostic information to guide personalized patient care.
