Final answer:
The abbreviation for Positron Emission Tomography is PET. This medical imaging technique uses radiopharmaceuticals to illustrate physiological activity within the body and diagnose various conditions.
The correct answer is options 1
Step-by-step explanation:
The abbreviation for Positron Emission Tomography is PET. Positron emission tomography (PET) is a sophisticated medical imaging technique that uses radiopharmaceuticals, which are substances that emit short-lived radiation, making them safer for body administration. PET scans provide detailed information about the physiological activity of organs, including nutrient metabolism and blood flow, helping to diagnose conditions such as heart disease, cancer, brain disorders, and more.
Innovative radioisotopes like carbon-11 (¹¹ C), nitrogen-13 (¹³N), oxygen-15 (¹⁵O), and fluorine-18 (¹⁸F) are used in PET scans to track natural body compounds' function and structure, offering a resolution better than SPECT and effectively diagnosing conditions like Alzheimer's disease. PET scans are notably useful for their accuracy and sensitivity in examining the brain's anatomy and function.
