Ultrasound of a 20-week-old fetus
Ultrasound examination services range from routine outpatient procedures to more difficult emergency procedures and ultrasound exams performed during surgery. Technologists are certified by the American Registry of Diagnostic Medical Sonographers (ARDMS) and the state of Texas. All registered and licensed health care professionals administer diagnostic tests under the supervision of a radiologist on the medical staff.
The terms ultrasound exam, ultrasound study and sonogram all mean the same thing and may be used interchangeably by medical personnel. Ultrasound imaging utilizes high frequency sound rather than X-rays to produce images of the body. Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs.
Like the X-ray, MRI, and CT scan, ultrasound imaging has its place as a diagnostic tool. Ultrasound scanning does not expose the individual to radiation and the procedure is painless and safe. Ultrasound imaging may be used to image a specific area of the body, such as the interior of the abdomen.
During a Doppler ultrasound, a handheld instrument called a transducer is passed lightly over the skin above a blood vessel to evaluate blood as it flows through a blood vessel, including the body's major arteries and veins in the abdomen, arms, legs and neck. This special technique can show blocked or reduced blood flow and can reveal blood clots in leg veins.
- Ultrasound scanning is noninvasive (no needles or injections), does not use ionizing radiation, and is usually painless
- Ultrasound scanning gives a clear picture of soft tissues that may not show up clearly on x-ray images
- Ultrasound has no know side effects and may be repeated as often as necessary if medically indicated
- Ultrasound provides real-time imaging, making it a good tool for guiding minimally invasive procedures such as needle biopsies and needle aspiration of fluid in joints or elsewhere
The Patient Order Form is needed for all outpatient exams.
