Administer medical substances for imaging or other procedures.

Administer medical substances for imaging or other procedures. is a detailed work activity in O*NET — a concrete unit of work shared across 6 occupations and seen in 6 occupation-specific tasks. It rolls up into the broader work activity Administer basic health care or medical treatments. in Assisting and Caring for Others .

Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.

AI exposure

Of the 6 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 1 (17%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).

Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.

Member tasks

Occupation-specific tasks O*NET maps to this detailed work activity, most important first.

• Administer radiopharmaceuticals or radiation intravenously to detect or treat diseases, using radioisotope equipment, under direction of a physician. · Nuclear Medicine Technologists · importance 4.9 · no direct exposure
• Identify and outline bodily structures, using imaging procedures, such as x-ray, magnetic resonance imaging, computed tomography, or positron emission tomography. · Medical Dosimetrists · importance 4.8 · exposure with tools
• Inject contrast medium into patients' blood vessels. · Cardiovascular Technologists and Technicians · importance 4.6 · no direct exposure
• Intravenously inject contrast dyes, such as gadolinium contrast, in accordance with scope of practice. · Magnetic Resonance Imaging Technologists · importance 4.6 · no direct exposure
• Administer radioisotopes to clinical patients or research subjects. · Radiologists · no direct exposure
• Inject contrast media into patients' blood vessels. · Cardiologists · no direct exposure
