SONOGRAPHY OF SELECTED MUSCLE DISEASES OF THE CANINE HIND-LIMB

The potential use of sonography of canine hind limbs to diagnose muscl e diseases was studied. The morphological changes detected and the tec hniques used on selected cases are described. Neoplastic changes, whic h cannot be differentiated into malignant and benign by the method, su ppurative inflammation and muscular contractures, in the m. quadriceps , m. gracilis and m. semitendinosus, were characterised. For these exa minations a 7.5 MHz linear transducer was most appropriate. Ultrasonog raphy was shown to be useful to display and localise these muscular ch anges, and to identify their margins with surrounding tissues.
