Which healthcare professional uses radionuclides in diagnosis and treatment?

The use of radionuclides in diagnosis and treatment is primarily associated with the role of a nuclear medicine technologist. This healthcare professional specializes in administering radioactive materials for diagnostic imaging and therapeutic purposes. They are trained to prepare and inject radionuclides, which are substances that emit radiation and can be tracked in the body using specialized imaging equipment. This process allows for detailed visualization of organ function and structure, aiding in the diagnosis of various medical conditions.

A radiological technician focuses on imaging techniques like X-rays and CT scans, while a radiologist interprets those images but does not typically handle radionuclides directly. An ultrasound technician specializes in the use of sound waves to create images of the body and does not work with radioactive materials. Therefore, the unique knowledge and skills of a nuclear medicine technologist that pertain to radionuclide usage distinctly identify their pivotal role within the healthcare system.
