Throughout the treatment The sonographer moves the transducer back and forth softly on your tummy. The gadget transmits signals to a computer, which generates graphics depicting how blood flows through the tissues in your abdomen. A standard ultrasound exam lasts roughly 30 minutes. Abdominal ultrasounds are useful in detecting possible problems with the organs inside the abdomen As well as visualizing tumors and other abnormalities that may not be apparent during a physical examination. These images provide information about the size of organs such as the liver and kidneys as well as detect blockages or problems with them. Abdominal scans can also reveal hernias (openings in the muscle wall of the abdomen), intestinal diseases, and tumors. An abdominal ultrasound is usually done as part of a larger test called a "fetal ultrasound." This test can show whether the baby is healthy and if there are any problems with its development. A fetal ultrasound involves checking the growth of the fetus and determining the presence of defects by listening to the heart and lungs with special instruments called transducers. A normal abdominal ultrasound shows a smooth contour of the liver and spleen without masses or lesions. The intestines should appear looped within the scan. The small and large intestines can be seen separately or together depending on the patient's position.
