Diagnostic Ultrasound for Rheumatology?

I'm a rheum fellow nearing graduation. Currently being trained (not certified) in diagnostic ultrasound. Has anyone out there found it useful to implement in their practice? Has anyone used this in place of getting xrays on some of your patients? It seems to be the one procedure that rheumatologists can do that has reasonable reimbursement (unlike ultrasound guided joint injections.) Just wanted to get a sense of its clinical utility in day to day practice.
