Classification of hepatobiliary scintigraphy patterns in segmented gallbladder according to anatomical discordance

Figure 4 Gallbladder ejection fraction in non-segmented gallbladder and segmented gallbladder subtypes. Reported gallbladder ejection fraction (GBEF) in non-segmented gallbladder (GB) was 67.40% ± 21.78%, whereas that of segmented GB was 62.50% ± 24.79% for Type 1, 75.89% ± 17.21% for Type 2, and 88.56% ± 7.20% for Type 3. ^aThere was a significant difference between reported GBEF of Types 1 and 3; ^bThe difference in GBEF of Types 1 and 2 was not statistically significant (P = 0.082). GB: Gallbladder; GBEF: Gallbladder ejection fraction.
