Final answer:
PET Scan uses a radiopharmaceutical injection and a specialized camera to detect radiation emitted from the patient. It provides details on both the structure and function of organs, making it useful in diagnosing various conditions.
Step-by-step explanation:
The modality that uses a radiopharmaceutical injection and is imaged using a specialized camera that can detect the radiation emitted from the patient is PET Scan.
PET stands for Positron Emission Tomography. A radioactive isotope is either injected into a vein, swallowed, or inhaled as a gas. The gamma ray emissions from the radioisotope are detected by a PET scanner, which works with a computer to generate special pictures, providing details on both the structure and function of various organs.
Unlike other imaging techniques like CT scans or X-rays, PET scans can measure the metabolic activity of cells and are particularly useful in diagnosing and monitoring conditions such as cancer, heart disease, and brain disorders.
