What clinical condition could warrant a Tc mebrofenin scan?

• A. Acute pancreatitis
• B. Gallbladder dysfunction due to RUQ pain
• C. Renal failure
• D. Sepsis

Answer: (B)

A Tc mebrofenin scan is primarily utilized for assessing hepatobiliary function and can evaluate conditions related to the gallbladder and bile ducts. In the context of gallbladder dysfunction, which may present as right upper quadrant (RUQ) pain, a Tc mebrofenin scan allows healthcare professionals to visualize the biliary system and assesses gallbladder filling and function. This can help confirm or rule out conditions such as acute cholecystitis or biliary obstruction, which can be associated with RUQ pain.

The technique relies on the injection of a radiopharmaceutical that mimics the behavior of bilirubin, enabling visualization through imaging. When there is suspicion of gallbladder issues stemming from RUQ pain, this scan provides valuable diagnostic information for appropriate management.

In contrast, the other options do not align as directly with the purposes of a Tc mebrofenin scan. Acute pancreatitis typically requires imaging techniques like CT or ultrasound for evaluation of the pancreas. Renal failure is assessed through renal scans using different agents, focusing on renal perfusion and function. Sepsis may require imaging to identify a source of infection but is not typically evaluated with a hepatobiliary scan. Thus, the indication for a Tc mebrofen
