Which of the following is a duty of a radiologic technologist?

A radiologic technologist is primarily responsible for performing imaging procedures that create visual representations of the interior of the body, most commonly through techniques such as X-rays, CT scans, MRI, and ultrasound. This role requires specialized training in the operation of imaging equipment, understanding human anatomy, and ensuring patient safety during procedures.

Performing imaging procedures involves not only technical proficiency with the machines but also knowledge of how to position patients effectively and communicate with them to obtain the best diagnostic images. Additionally, radiologic technologists must follow safety protocols to minimize radiation exposure to both patients and themselves.

This specialization sets radiologic technologists apart from other healthcare professionals. For example, the other options listed involve skill sets and responsibilities more aligned with different professions within healthcare, such as pharmacology, psychology, and nutrition. Therefore, the focus on imaging procedures makes this option the correct answer.
