Flexor Surface of the distal sesamoid bone: do we see the same at ultrasound and magnetic resonance imaging?

The objective of this study was to compare ultrasonographic and magnetic resonance imaging features of the facies flexoria in 13 cadaver limbs with no known history of lameness. Overall, fibrocartilage thickness was better assessed on MR images, but this modality presented a high number of false-positive results. Ultrasonography had a poorer sensitivity than magnetic resonance imaging but better specificity (however conserving a fairly high number of false-positive results).
