Ultrasound utilizes high frequency sound waves, without radiation, to generate images of the internal structures of the body. The reflected sound wave echoes are recorded and displayed as a real-time visual image. Because ultrasound images are captured in real-time, they can show movement of internal tissues and organs, and enable the CMI Radiologists to see blood flow and heart valve functions.   Many different types of ultrasound procedures are performed at the Center for Medical Imaging. Ultrasound is able to capture moving images of pelvic and abdominal function (including gallstones), venous and carotid ultrasound, the male

reproductive system, the kidney and thyroid systems, as well as the developing fetus, among other applications. When enhanced with a special Doppler technique, ultrasound can also capture moving blood images of large blood vessels.

Preparing for your exam

• Abdomen, Gallbladder: Do not eat or drink anything six hours prior to your exam time.
• Pelvic Ultrasound: You need a full bladder – do not empty your bladder two hours prior to your appointment time. One hour prior to your exam, drink at least 32 ounces of fluid. Do not empty your bladder. No fasting is necessary.
• Preparation for some ultrasound studies will depend on the type of exam. If your exam is not listed, please contact a CMI representative to obtain specific instructions.

During your exam – what to expect

• You will lie on a comfortable table while a Technologist performs the exam. A handheld device, called an ultrasound probe or transducer, will be moved on the surface of the skin in the area of interest after a liquid gel is placed on the probe and/or the skin.
• For certain ultrasound exams, specialized internal probes are used. For example, an endovaginal probe is used for most pelvic exams to create the most detailed images of the uterus and ovaries. Digital images are instantly captured on a television-like monitor and transferred for a radiologist to review and interpret. Depending on the type of exam, it can take anywhere from 20-60 minutes.

After your exam – what to expect
Your activity will not be restricted. You may drive if you wish, resume your normal diet, exercise and take medications, as directed. The Center for Medical Imaging’s radiologist will review your ultrasound and send a diagnostic report to your doctor. Your doctor will review this information in context of your care, and talk with you regarding the results.
