From: Elastosonographic features of the metacarpophalangeal joint capsule in horses
Transverse (a) and longitudinal (b) elastosonographic images of the distal attachment of the fetlock joint capsule (DJC) showing the positioning of the ROIs over the DJC (yellow circle) and the dorsal digital extensor tendon (DDET) (green circle) in one horse of Group S. The top left box shows the elastogram of the transverse (a) and longitudinal (b) scans of the DJC with the superimposed ROI above the DJC (yellow) and DDET (green) in Group S. The bottom left box shows the conventional B-mode image of a transverse and a longitudinal scan of the DJC with the superimposed ROI above the DJC (yellow) and DDET (green). The box at the right side of the image shows the graph produced by the software: the x-axis is time-dependent with green segments indicating the moments of proper pressure and red segments the incorrect ones. The y-axis shows the EI values for the DJC (yellow) and DDET (green). The values of EI are expressed at the top right side of the image. SR, not shown, is then calculated by the software (ROI: region of interest; DJC: distal attachment of the joint capsule; DDET: dorsal digital extensor tendon; EI: Elasticity Index; SR: Strain Ratio)
