Ultrasound imaging, or sonography, uses high-frequency sound waves to get images of the inside of the human body. An ultrasound is a diagnostic tool that can assist doctors in making recommendations for further treatment.
At Pleasanton Diagnostic Imaging, we recently added two new ultrasound machines that include 3-D imaging for more comprehensive, highly detailed imaging.

What are some common uses of ultrasound?
Ultrasound is most commonly used to:
- View an unborn fetus
- Examine internal organs, including the liver, gallbladder, spleen, pancreas, kidneys, bladder, uterus, and ovaries
- Examine blood flow
- Evaluate superficial structures, such as the thyroid gland and testicles
- Evaluate deep vein thrombosis (DVT) using lower extremity vascular ultrasound
What should I expect during this exam?
Your ultrasound exam at Pleasanton Diagnostic Imaging will follow these steps:
- Our technologist will position you on an exam table and apply a clear gel to the area being examined. This helps the transducer make contact with the skin.
- The technologist will firmly press the transducer against the skin and move it back and forth to image the area.
- After the examination is complete, the technologist may ask you to wait while the ultrasound images are reviewed by the radiologist.
What will I experience during this exam?
Most ultrasound exams are painless. However, you may experience slight discomfort and pressure as the technologist guides the transducer over your body, especially if you have a full bladder.
How should I prepare for an ultrasound?
Your preparation depends upon the area of your body being examined:
- Abdomen: Nothing to eat or drink after midnight before your scheduled appointment. Any medications may be taken with a small amount of water.
- Abdomen/pelvis: Nothing to eat or drink after midnight. Empty bladder then drink 32 ounces of water one hour before your scheduled appointment. Do not use the restroom; your bladder must be full.
