question: The ultrasonography is frequently used to diagnose muscular lesion and to accompany the scaring. The goal of this research was to verify the correlation between the ultrasonographic image and the macroscopic one, having at the end, the histologic correspondent study. Thirty rabbits of New Zealand race have been used, submitted to muscle tibial cranial complete lesion, evaluated with ultrasonography, photographs during the surgery (macroscopy) and histologic study (microscopy) in different period during the sacrification (1st, 2nd and third week). We conclude that it exists correlation among the ultrasonographics, macroscopics and microscopics images.
