Ultrasound, also called sonography, uses high-frequency sound waves to create video images of soft tissue areas of the body.
Comprehensive Ultrasound Imaging
Parkland Medical Center offers several types of ultrasound imaging, including endoscopic, echocardiogram and obstetric ultrasound using conventional, 3-D and 3-D color technology. We use ultrasound imaging to examine internal organs, including the gastrointestinal tract, thyroid gland and reproductive systems and to guide procedures such as needle biopsies. Our heart and vascular care specialists use color-flow Doppler ultrasound to measure the extent of peripheral vascular disease and to evaluate the heart, heart valves and major vessels while blood flows through them.
Our diagnostic specialists also perform carotid ultrasound exams to assist physicians in viewing and evaluating blood flow and blockages that help detect disease in the carotid/vertebral arteries in the neck. This test may be ordered to help diagnose a stroke, a transient ischemic attack (TIA), dizziness, vertigo or headaches.
How You Benefit
Ultrasound tests are noninvasive, painless and cost effective. Because ultrasound images are captured in real time, they can illuminate complex bodily functions such as blood flow and heart valve operation. That means your doctor uses safe, high-quality images to guide your care and treatment.
What to Expect
For an ultrasound exam, follow the instructions provided by your physician before your appointment. During the ultrasound exam, our registered sonographer spreads a special gel on the part of the body being examined and presses the transducer against the skin to capture the image. At the same time, you can watch the ultrasound images on a specially positioned screen. The exam usually takes less than 30 minutes. A radiologist will analyze the images and report the results to your doctor.
