Ultrasound

Ultrasound

We use ultrasound (US), or sonography, to obtain images from inside your body through the use of high frequency sound waves. We record echoes of the sound waves and display them as real-time, visual images. There is no radiation involved in ultrasound imaging. We use US to examine internal organs including the liver, gallbladder, spleen, pancreas, kidneys, and bladder as well as soft tissue structures such as the breasts, thyroid, and testicles. We also use ultrasound to assess blood flow within organs or blood vessels or to guide interventional procedures such as biopsies.
For women, pelvic ultrasound is most often used to examine the uterus and ovaries and, during pregnancy, to monitor the health and development of the embryo or fetus. In males, a pelvic ultrasound usually focuses on the bladder and the prostate gland.
Recently, we have used ultrasound to examine the musculoskeletal system of the body to detect problems with muscles, tendons, joints, and soft tissue. We view the images in real time so they can show movement, function, and anatomy, as well as enable the radiologists to diagnose a variety of conditions and assess damage after an injury or illness.

Ultrasound General Preparation

Wear comfortable, loose fitting clothing for your ultrasound exam.

Ultrasound Procedure Specific Preparation

Pelvic/Obstetric

Your bladder must be full. You will have the urge to urinate with a full bladder. IF YOUR BLADDER IS NOT FULL ENOUGH, YOUR STUDY MAY BE DELAYED OR RESCHEDULED. Empty your bladder two hours before the exam, then drink four (4) 8oz glasses of water. Do not urinate until after your exam. The more slowly your bladder fills, the less uncomfortable it will be. For late-term obstetric cases (after 30 weeks), no preparation is necessary.

Abdomen/Gallbladder

Have a light dinner no later than 7pm the night before your exam. Do not eat again until after your exam. You should fast for at least 8 hours. You may take medications with a small amount of water. Please call our office if you have any questions.
