Compounded versus proprietary sincalide for evaluation of gallbladder ejection fraction.

Objective: To report a comparison of compounded and proprietary sincalide in the evaluation of gallbladder ejection fraction during hepatobiliary scintigraphy.

Case Summaries: Two patients were referred to nuclear medicine with symptoms consistent with hepatobiliary dysfunction. Both underwent hepatobiliary scintigraphy to evaluate anatomic and physiologic tract patency of the hepatobiliary system.

A parathyroid cyst with adenoma on thallium-201/technetium-99m subtraction imaging.

A case of a parathyroid cyst with adenoma was seen on Tl-201/Tc-99m subtraction imaging. The literature regarding parathyroid cysts and the subtraction technique for parathyroid adenoma imaging was reviewed.

Visualization of acute hepatic necrosis with a bone imaging agent.

A case of massive hepatic necrosis has been found to have intense, diffuse accumulation of Tc-99m HMDP in the liver. A review of three similar cases revealed that diffuse intense uptake of bone-scanning agents is a grave prognostic sign.
