At Liv Hospital, our diagnostic pathway for gallstone disease is a rigorous, multi-tiered process designed to establish a precise anatomical and functional diagnosis. We recognize that “abdominal pain” is a non-specific symptom that can mimic cardiac ischemia (inferior MI), peptic ulcer disease, pleurisy, or musculoskeletal pathology. Therefore, our diagnostic definition involves confirming the presence of stones, assessing the patency of the biliary tree, and ruling out complications such as malignancy or severe infection. We use a combination of biochemical markers, functional studies, and advanced cross-sectional imaging, following the Tokyo Guidelines (TG18) for diagnostic grading.
While blood tests cannot visualize stones, they are essential for assessing the physiological impact of the disease on the hepatobiliary system.
Ultrasound is the Gold Standard, first-line imaging modality for cholelithiasis globally.
When ultrasound findings are equivocal, or there is biochemical evidence of a bile duct stone (elevated ALP/Bilirubin) not seen on ultrasound (due to bowel gas interference), Liv Hospital employs MRCP.
Also known as Cholescintigraphy, this is a physiological (functional) nuclear medicine study used when the anatomy appears normal, but the physiology is suspected to be defective.

Ultrasound is significantly superior. Because gallstones are often composed of cholesterol, they do not block X-rays effectively and can be invisible (radiolucent) on a CT scan. Ultrasound relies on sound reflection from the stone’s physical interface, making it the most accurate test for detecting gallbladder stones.
The HIDA scan involves a minimal amount of radioactive tracer, roughly equivalent to or less than a standard X-ray or CT scan. The tracer has a short half-life (6 hours) and is rapidly cleared from the body through the biliary and renal systems, making it a safe and highly effective test for assessing gallbladder function.
MRCP is a diagnostic imaging test (MRI) used purely to “look” at the bile ducts non-invasively. ERCP is a therapeutic invasive procedure involving a tube passed down the throat, used primarily to “act” (remove stones, place stents). We typically use MRCP to confirm the diagnosis and ERCP only if intervention is required.
While ultrasound confirms the anatomy (the presence of rocks), blood tests reveal the physiology (the impact on the liver). Elevated liver enzymes (such as bilirubin or ALP) indicate whether a stone has escaped the gallbladder and blocked the common bile duct, which significantly changes the urgency and type of surgery required.
Yes, biliary sludge appears on ultrasound as a low-amplitude echo pattern that layers in the dependent (bottom) part of the gallbladder. Unlike stones, it does not cast a hard acoustic shadow and moves slowly like a viscous fluid (a “fluid-fluid level”) when the patient changes position.
