This meticulously designed lesson by Robert Christman, DPM, Director of Radiology at the Temple University School of Podiatric Medicine, teaches x-ray evaluation and interpretation by example. By the end of this presentation, the participant will be able to: (1) Identify subtle radiographic abnormalities that will allow early diagnosis of disease. (2) Use appropriate terminology to describe specific radiographic lesions, including infection, dysplasia, arthritis, tumor, osteonecrosis, anomaly, and metabolic/endocrine disorders. (3) List differential diagnoses for specific radiographic abnormalities. (4) Distinguish between diseases that appear similarly radiographically.
