Radiology Practicum Solved
Exam Questions
Course Introduction
Radiology Practicum offers students hands-on experience in a clinical radiology setting, integrating theoretical knowledge with practical skills. Under professional supervision, students participate in imaging procedures such as X-rays, CT scans, MRI, and ultrasound, learning proper patient positioning, safety protocols, and operation of radiologic equipment. Emphasis is placed on image evaluation, radiographic anatomy, patient care, and adherence to radiation protection standards. The practicum fosters the development of effective communication skills with healthcare teams and patients, preparing students for professional roles as radiology technologists.
