MRI scans from a 65 year old female rheumatoid arthritis patient with disease duration of one year. (a) Coronal T1 weighted image of the dominant wrist with reduced signal indicating florid bone oedema involving the entire lunate bone (circle). (b) Equivalent image following the injection of contrast (gadolinium diethylenetriamine pentaacetic acid (GdDPTA)) shows very bright signal within the lunate, suggesting the presence of vascularized tissue (slice does not exactly correspond with pre-GdDPTA image). (c) Axial T2w image with bright signal confirming bone oedema at the lunate.
