Ultrasound or Sonographic imaging is a painless, non-invasive imaging procedure which complements Radiographic (X-Ray) imaging and utilizes sound waves to evaluate internal organs. Sonographic imaging also allows for guided biopsies, which can sometimes eliminate the need for exploratory surgery. Ultrasound imaging can often determine the extent of a disease process, visualize mineral and urinary tract stones not visible on x-rays, evaluate for a source of pain and determine the origin or presence of a mass or cancer.
Ultrasound is a particularly valuable tool to diagnose pancreatic disease in dogs and cats. The pancreas is often not visible on radiographs (x-rays) and at times laboratory tests are not conclusive for pancreatic disease.
