RADIOGRAPHY OF THE EQUINE THORAX: ANATOMY AND TECHNIC

Abstract

Radiographic evaluation of the entire adult equine thorax in the standing position requires a minimum of four overlapping lateral radiographs. Small horses could often be studied with fewer radiographs. This basic examination provided the optimal radiographic opportunity for detecting lung diseases in the horse. An understanding of normal gross and radiographic anatomy is an absolute necessity if one is to avoid the potential diagnostic pitfalls inherent in radiographic interpretation of the equine thorax. Of equal importance is an appreciation for the technic required to produce thoracic radiographs. The advent of rare‐earth intensifying screen and highspeed film systems has enhanced the opportunity for obtaining diagnostic standing lateral equine thoracic radiographs.
