Radiology is the study of images of the human body for diagnostic purposes.
A radiologist correlates imaging findings with other examinations and tests, recommends further examinations or treatments, and confers with the physicians who referred the patient. In this way, specific diagnostic and therapeutic maneuvers can be effected via these instruments under imaging guidance. The residency provides the core set of skills and knowledge that is required of all radiologists. The core skills include the ability to interpret x-rays, fluoroscopy, mammography, CT scans, and ultrasound images. Following a successful residency, radiologists may choose to enter a fellowship program to gain subspecialty expertise.
