What does ultrasound show, and what happens during the exam?
During an ultrasound exam, gel is applied to the skin over the area being examined, and a transducer is moved over the skin to capture images. The device emits high-frequency sound waves that bounce back from the tissues, showing organs and other anatomical structures in real time. During certain musculoskeletal exams, the joint or tendon can also be observed while it moves.
Ultrasound is a very useful test, but it can’t examine every organ and abnormality equally well. Areas filled with air, such as the bowel, and areas behind bone are harder to see, for example, and in some cases CT, MRI, X-ray, mammography, or another targeted test provides more suitable information. That’s why an ultrasound report should always be interpreted together with your symptoms, your medical history, and, when needed, other test results.
Do you need imaging for abdominal symptoms, a palpable lump, joint pain, or a vascular problem? Choose the right ultrasound exam, or ask a specialist to help determine which imaging method can answer your question.
