Radiologic technologists are highly skilled medical imaging professionals who work closely with physicians to perform procedures used to diagnose, monitor, and treat disease. They provide patient services using a variety of imaging modalities such as general x-ray, magnetic resonance imaging (MRI), computerized axial tomography (CT-scan), cardiovascular-interventional technology, mammography, bone densitometry, and quality management. Students finish their general education requirements and program prerequisites (biology, chemistry, anatomy, physiology, medical terminology, and statistics) during their freshman and sophomore years. The professional phase of the program then begins and consists of six consecutive semesters of classroom courses integrated with clinical experiences at several facilities in Columbia, MO. The program places an emphasis on active learning and provides many opportunities to develop skills needed for future education and career advancement. Upon graduation students are well-prepared to sit for the national registry exam in general diagnostic imaging. An advanced imaging clinical externship is available to MRI and CT students who wish to gain competency in those areas and become registered in MRI or CT. Graduates may work in a variety of settings including hospitals, clinics, imaging centers, mobile services, research centers, and industry as staff technologists, specialty technologists, supervisors, managers, applications specialists, researchers, or educators. Hospital settings give technologists an opportunity to choose working hours around the clock, throughout the entire 7-day week and may require on-call hours.
