This test evaluates all the internal organs within the abdomen. These include the pancreas, liver, gallbladder, both kidneys and spleen. We search for abnormal variations such as cysts, tumors, stones, or free fluid within the abdomen. We measure all the organs to check for enlargement. We also evaluate for blood flow abnormalities. This test lasts approximately 30 minutes and requires the patient to fast for eight hours prior to the test mainly because our biggest obstacle is overlying bowel gas, which obscures our ability to visualize the organs clearly.
