Precision of the gallbladder ejection fraction obtained with Tc-99m-pyridoxyl-5-methyl-tryptophan (99mTc-PMT) hepatobiliary scintigraphy as compared with the contraction ratio in three-dimensional computed tomography

Abstract

The %ID of the gallbladder obtained with hepatobiliary scintigraphy may be a good indicator of the volume of the gallbladder. The accuracy of GBEF was confirmed by comparison with 3D-CT examination. GBEF is considered a useful parameter of pathophysiological gallbladder function.

Oral Cholecystagogue Cholescintigraphy

“…[1][2][3][4] It is often used in the evaluation of patients with chronic right-upper-quadrant abdominal pain in the context of a structurally normal gallbladder by anatomic imaging (ie, ultrasound or CT). In this setting, a low gallbladder ejection fraction (GBEF) may signify abnormal gallbladder contractility as the cause of the patient's symptoms, known as functional gallbladder disorder.…”
