A Diagnostic Ultrasound (mobile DUS tests) utilizes frequencies over 20,000 Hz which cannot be heard by human beings. It signals the doctor what is inside his patient anatomically and physiologically.
A computer translates echoes into an image on a television screen. Because of the differences in echogenicity of soft tissues, especially the finite variations of fluid filled tissues, ultrasound provides diagnostic images of the abdomen including the liver, gallbladder and tracts, pancreas, spleen, kidney, ureter, bladder and prostate.
All major insurance carriers pay for appropriate diagnostic ultrasound testing. Diagnostic ultrasound does not use ionizing radiationi and no adverse effects on patients have ever been reported since its decades of use. Even Ob-Gyn doctors use it to evaluate fetal abnormalities.
