An : An ultrasound can suggest what it is bit is not definitive. An ultrasound looks at fluid changes so for a cyst it is good to see the transition from the awl of the cyst to the inside fluid layer. Stll where it is can also influence the ultrasounds ability to discern detail. I.E. Behind a bone the sound waves may not get through as well. While the tech may give someone preliminary info one really needs to wait for the formal report and for the ordering physician to review it and make sur the findings correspond and are relevant to the problem. This last reason is why a lot of physicians/surgeons are starting to do their own musculoskeletal ultrasound in their own office setting. The ability for a surgeon who knows the anatomy primarily to see structures and do a relevant physical exam at the same time becomes of great value.

Be : Be patient and wait for the reading from the radiologist. Don't make your own diagnosis.

Unless : Unless you are experienced reading ultrasounds, wait for the radiologist to review and interpret it for you.
