Diagnostic Tests: Right Upper Quadrant (RUQ) Ultrasound
Clinical Scenarios Where RUQ Ultrasound Is the Correct Answer
A right upper quadrant ultrasound is the first-line imaging test when a patient presents with right upper quadrant abdominal pain, with or without fever. It is specifically designed to evaluate the hepatobiliary system and is highly effective for identifying both liver and biliary tract pathology. RUQ ultrasound is appropriate when assessing:
Most Accurate Diagnostic Tests
While RUQ ultrasound is the best initial test, the most accurate diagnostic tests depend on the suspected pathology:
Significance of Pain During RUQ Ultrasound
If the patient experiences marked tenderness when the ultrasound transducer presses over the gallbladder, this finding is known as a positive Murphy’s sign. A sonographic Murphy’s sign is highly suggestive of acute cholecystitis, especially when accompanied by gallstones, gallbladder wall thickening, or pericholecystic fluid on ultrasound.

A right upper quadrant ultrasound is the first-line imaging test when a patient presents with right upper quadrant abdominal pain, with or without fever. It is specifically designed to evaluate the hepatobiliary system and is highly effective for identifying both liver and biliary tract pathology. RUQ ultrasound is appropriate when assessing:
- Liver pathology, including:
- Hepatic masses (tumors, abscesses, cysts)
- Evidence of portal hypertension
- Gallbladder and biliary tree disorders, such as:
- Cholelithiasis
- Acute or chronic cholecystitis
- Choledocholithiasis
- Cholangitis
Most Accurate Diagnostic Tests
While RUQ ultrasound is the best initial test, the most accurate diagnostic tests depend on the suspected pathology:
- Biliary pathology (stones, obstruction, cholangitis):
- ERCP (Endoscopic Retrograde Cholangiopancreatography)
- MRCP (Magnetic Resonance Cholangiopancreatography)
- Liver pathology (tumors, diffuse liver disease):
- Liver biopsy is the most accurate test
