Examples of MRI-detected synovitis and tenosynovitis with corresponding greyscale and power Doppler ultrasound images. Examples of inflammation identified by MRI that were verified through ultrasound (US). Even though sometimes more inflammation was present on the MRI scan, we choose to show the corresponding US images of only one joint or tendon that was present on the image. a An example of synovitis MCP-3 by MRI, which was confirmed by greyscale (GS) and power Doppler (PD) US images of the same joint. b Tenosynovitis of the flexor of MCP-4 which was confirmed by GS but not by PD on US. c Inflammation of the extensor carpi ulnaris tendon at the wrist level which was confirmed by both GS and PD on US
