This document discusses basic concepts in radiology. It emphasizes that one view alone is not sufficient, and that patterns seen on images provide clues. Radiologists must be sure to look at all available views, know what they are looking for based on clinical information, and understand the limitations of different imaging tests. Seeing the whole picture and considering what each test can and cannot show is important for accurate diagnosis.
