The computed tomography of normal long bone anatomy and its simulation of disease

Abstract

Normal bony anatomy as depicted by computed tomography (CT) may, in the region of the knee, hip and shoulder, incorrectly suggest the presence of pathology. Cortical destruction and new bone formation may be simulated at these sites. The normality of the medullary cavity and of the soft tissues are important in differentiation from genuine pathological lesions, with which comparisons are made.
