Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses high-frequency sound waves to produce images of internal body structures.
Compared to other prominent methods of medical imaging, ultrasonography has several advantages. It provides images in real-time. It is portable and can be brought to a patient’s bedside, it is substantially lower in cost, and it does not use harmful ionizing radiation.
- Abdominal Organs: Pancreas, Liver, Gallbladder, Spleen and Kidneys and Bladder.
- Pelvic Structures: Uterus and Ovaries.
Ultrasound can be enhanced with Doppler measurements. Using Ultrasound, Color and Pulsed Doppler imaging is often described Duplex Imaging.
Duplex Doppler ultrasound is a form of ultrasound used to evaluate blood flow through major arteries and veins, such as those of the arms, legs, abdomen and neck. It can show blocked or reduced flow of blood within the arteries and veins.
- Aortic Duplex
- Carotid Duplex
- Venous Duplex
- Arterial Duplex
An ABI exam, or Ankle Brachial Index is another Doppler exam performed to predict the presence of peripheral arterial disease. This test is performed utilizing a hand held doppler and performing blood pressures in both arms and both ankles. Doppler waveforms are also done in the distal arteries of the legs.
Gamma offers mobile ultrasound results within two hours of the exam being performed.
