Ultrasound: What to Expect
Frequently Asked Questions
Why is This Exam Done?
Musculoskeletal ultrasounds can be used to detect tears in tendons, as well as benign and malignant tumors in soft tissue. This procedure will also detect bleeding or fluid build-up in muscles and joints. Musculoskeletal ultrasounds allow physicians to monitor the early changes of rheumatoid arthritis.
How Does it Work?
Ultrasound uses high-frequency sound waves to produce images of the body’s tissues, structures, and blood flow. A transducer/probe and ultrasound gel work in combination to absorb the reflected sound waves to produce images on the monitor
What Will Happen During the Exam?
The sonographer will request that you lay quietly during the test to help ensure that the images are clear. Warm, water-based gel will be applied to the ultrasound transducer or directly on the skin. The sonographer will then move the transducer around on the area to obtain clear images of the underlying structures for the physician to interpret.
The procedure typically lasts for 30 minutes, but the duration varies depending on the structure being examined.
How Should I Prepare?
Before the test is administered, you may be asked to change into a gown.
