Dr Öncel Yakar’s comments
Gallstones are mostly detected on abdominal ultrasonography. It can be seen in diagnostic imaging in patients with complaints regarding the upper gastrointestinal tract, or if there is any pathology in the gallbladder on ultrasound requested for check-up or other clinical reasons (for example, kidney stones). In order for the ultrasound technology, which is based on sending sound waves with a transmitter and converting the returning wavelength into an image, to detect stones in the gallbladder, the gallbladder must be distended with at least 6 hours of fasting. Tests on satiety can be misleading. In addition to the most commonly used ultrasound in the diagnosis of cholelithiasis, it is possible to diagnose with MRCP, a special type of Magnetic Resonance Imaging, or with Endoscopic Ultrasonography (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP), which are more invasive methods.
