Ultrasound Imaging in McAllen, TX
Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body.
Ultrasound exams do not use ionizing radiation (as used in x-rays). Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels. Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
Conventional ultrasound displays the images in thin, flat sections of the body. Advancements in ultrasound technology include three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images. Four-dimensional (4-D) ultrasound is 3-D ultrasound in motion. Ultrasound examinations can help to diagnose a variety of conditions and to assess organ damage following illness.
Ultrasound is used to help physicians evaluate symptoms such as: pain swelling infection Ultrasound is a useful way of examining many of the body's internal organs, including but not limited to the:

- guide procedures such as needle biopsies, in which needles are used to extract sample cells from an abnormal area for laboratory testing.
- image the breasts and to guide biopsy of breast cancer (see the Ultrasound-Guided Breast Biopsy page).
- diagnose a variety of heart conditions and to assess damage after a heart attack or diagnose for valvular heart disease.
Doppler ultrasound images can help the physician to see and evaluate:
- blockages to blood flow (such as clots).
- narrowing of vessels (which may be caused by plaque).
