How Are Gallstones Diagnosed?
Many times gallstones are detected during an abdominal x-ray, computerized axial tomography (CT) scan, or abdominal ultrasound that has been taken for an unrelated problem or complaint.
When actually looking for gallstones, the most common diagnostic tool is ultrasound. An ultrasound examination, also known as ultrasonography, uses sound waves. Pulses of sound waves are sent into the abdomen to create an image of the gallbladder. If stones are present, the sound waves will bounce off the stones, revealing their location.
Ultrasound has several advantages. It is a noninvasive technique, which means nothing is injected into or penetrates the body. Ultrasound is painless, has no known side effects, and does not involve radiation.
