Imaging of the back and sacroiliac region in horses is challenging due to the large body mass of the horse. For the head, neck and the appendicular skeleton CT and MRI facilitated imaging and the interpretation and understanding of radiographic findings. Unfortunately, up to now the large body mass of the horses prevent slice imaging techniques in alive horses. The imaging modalities in use are therefore Radiography and Scintigraphy. Radiography of the back and pelvis in a horse is difficult due to the large amount of scatter radiation and superimposition. Scatter radiation mainly originates within the specimen and increases exponentially with thickness of the tissues. To reduce the amount of scatter radiation on the film, a grid (parallel grid) is necessary. Scatter radiation on the film can also be reduced by good- that means narrow- collimation which results in less scatter and therefore an increases in image contrast. It should be kept in mind, that scatter radiation is not only affecting image quality but causes radiation to the people within the room. Since radiation dose is high, a good clinical indication is necessary to justify radiographs of the back or pelvis in a standing horse where at least one person is within the room. Also scintigraphy suffers from the large body mass, since the large amount of soft tissues attenuates the gamma emitters. The distance between the camera and the emitting bone is large in the spine and the sacroiliac region in comparison to the appendicular skeleton which results in attenuation as well. […]
