The aim of study was to describe normal anatomy of the origin of the suspensory ligament in the forelimb working horses by ultrasound and resonance magnetic. Working horses headed to a slaughter house were clinical examined, they were verified with absence injuries in the suspensory ligament in the forelimbs. Then ultrasound analysis was done and subsequently to the slaughter, resonance magnetic analysis with pieces cadaverous previously packed were done. Transverse and longitudinal images were obtained by ultrasound and with magnetic resonance longitudinal, transverse and dorsal images. In both diagnostic methods were obtained dorsal-palm and lateral-medial diameter measurements. Cross-sectional images demonstrated the rectangular shape of the suspensory ligament and longitudinal images characteristic fibrilar alignment of the ligament was observed. Regarding evaluation by magnetic resonance, in cross-sectional images a billobed shape of the ligament was visualized with a dark central zone and a white peripheral zone due to the signal intensities adopted by the different tissues that comprise it. In the longitudinal image smooth and uniform band appearance. In the dorsal image it was visualized as vertical lines, the intensity signal being from intermediate to high. Ultra sonography and magnetic resonance imaging allowed us to evaluate the varied time constitution that the origin of the suspensory ligament presented.
