Radiology is a four-year medical residency with common fellowships after. It is a basic element of medical care and frequently results in patient admission or diagnosis. The document outlines basic radiology concepts - one view is insufficient so use multiple views, patterns provide clues to diagnosis, ensure thorough image review, know what you're looking for, and understand test limitations. It provides examples of using pattern recognition and multiple views to correctly diagnose conditions like pneumonia subtypes, pneumothorax, pneumomediastinum, and fractures. It stresses using decision trees and understanding when secondary tests are needed based on initial findings and patient history.
