Radiologic Procedures
Practice Questions
Course Introduction
Radiologic Procedures is a course designed to introduce students to the fundamental techniques and protocols used in diagnostic imaging. The course covers the principles of patient positioning, image acquisition, and radiation safety for various radiologic examinations, including those of the chest, abdomen, spine, and extremities. Emphasis is placed on the proper use of radiographic equipment, understanding procedural steps, and ensuring quality patient care throughout the imaging process. Students will also learn about contrast media, procedural documentation, and strategies to minimize patient exposure while achieving optimal image quality.
