Ultrasound pictures of the gallbladder reveal a pear-shaped structure nestled under the liver’s right lobe. The gallbladder’s walls and ducts are visible, providing insights into its size, shape, and potential abnormalities. Ultrasound can detect gallstones, blockages, and thickening of the gallbladder’s walls, aiding in the diagnosis of conditions such as cholecystitis and cholangitis.
