Hepatobiliary Scanning in the Diagnosis of Acute Cholecystitis

Nuclear Medicine Tests for Acute Gastrointestinal Conditions

“…Duration of the early UA-HBS studies was for up to 1 hour. [43][44][45][46] It became obvious early on that extending the imaging to 4 hours or longer improves specificity of the study by allowing GB viz in cases with chronic cholecystitis (CC). [47][48][49][50][51][52][53][54] The range of sensitivity and specificity of this protocol for AC is 95%-97% and 93%-99%, respectively.…”

Radionuclide Imaging of Hepatic and Biliary Disease

“…With the delayed imaging protocol, there is a mean sensitivity of 97% and specificity of 96% from six reports with a total of 1426 patients. [13][14][15][16][17][18][19] The morphine protocol has a mean sensitivity of 96% and specificity of 94% from nine reports with a total of 172 patients. 15,[20][21][22][23][24][25][26][27][28] However, in a meta-analysis, Cabana et al 29 found that the morphine protocol was more specific than the delayed imaging protocol, although sensitivity was comparable.…”

Enterobiliary fistulae: A potential cause of a false-negative hepatobiliary study in the diagnosis of acute cholecystitis

“…The role of cholescintigraphy in the evaluation of suspected acute cholecystitis has been well established [2][3][4][5]. The sensitivity of hepatobiliary imaging in the detection of acute cholecystitis exceeds 95% [1].…”
