title: [Radiologic examination of the spine in "back problems" of the standing horse].
abstract: The radiological examination of the thoracolumbar spine of a horse with a potential back problem is most important in order to come to a diagnosis and the imaging method of choice. The use of parallel grid-cassettes, appropriate films, rare earth screens and aluminium filters requires radiographic equipment with an output of 60-120 kV and 25-90 mAs. By use of this technique in the standing horse it is possible to obtain radiographs of the summits of the dorsal spinal processes of the thoracolumbar spine from the first thoracic (T1) to approximately the third of fourth lumbar vertebrae (L3/4). Since the thickness of soft tissue is increasing from distal to proximal it is necessary to increase the output to image the processus articulares craniales et caudales. Therefore additional radiographs have to be taken.
