Final answer:
Radiology and cardiology are two specialties for nuclear medicine technologists, with radiology focusing on different imaging techniques and cardiology using radiotracers to study heart conditions.
Step-by-step explanation:
Two specialty areas for nuclear medicine technologists are radiology and cardiology. Technologists in radiology specialize in imaging techniques, including computed tomography (CT), magnetic resonance imaging (MRI), and mammography, which are essential tools for diagnosing various medical conditions. Cardiology specialists use radiotracers such as technetium-99 and thallium-201 to evaluate heart function and identify damaged heart tissue. The specialty of radiology does involve work with radiologists and the production of body images for medical analysis, whereas cardiology is focused on the diagnosis and treatment of heart diseases with the help of nuclear medicine imaging techniques like PET scans.
