Positron Emission Tomography (PET): PET scans use radioactive tracers that emit positrons, which interact with electrons inside the body; it helps detect diseases like cancer.
Magnetic Resonance Angiography (MRA): MRA is a specialized MRI technique that focuses on visualizing blood vessels within the body.
Radiotherapy: Radiotherapy is a treatment method that uses high-energy radiation (such as X-rays or gamma rays) to destroy cancer cells and shrink tumors.
