An ultrasound examination could be requested for many reasons. You will be most familiar with its use in obstetrics (medical care during pregnancy and childbirth) to look at the baby as it grows throughout the various stages of pregnancy. But there are also many other reasons that an ultrasound examination may be requested. For example, it is used to examine abdominal and other organs. Colour Doppler ultrasound can be used to watch blood flow in any of the arteries or veins throughout the various parts of your body. High-resolution ultrasound can be used to evaluate the musculoskeletal system (muscles, bones and joints related). Breast ultrasound is an important part of the assessment of any breast lump. Ultrasound can take high quality pictures or images of most parts of your body, which makes it an excellent diagnostic test.
For many types of scan, particularly pregnancy scans, the person who is carrying out the examination will be able to explain the images and results to you during or just after the scan has taken place. In other cases the sonographer will analyze the images and send a report with the interpretation of the scan to your referring doctor.
