Comparison of two- and three-dimensional ultrasound for volume estimation of the meal-stimulated gallbladder.

ABSTRACT:

Aim

To compare two- and three-dimensional (2D and 3D) ultrasound of the gallbladder in an adult cohort.

Material and methods

In this observational, cross-sectional study, gallbladder volumes were measured using 2D and 3D ultrasound. Examinations were performed in the fasting state and at predefined time intervals after ingestion of a standardized nutritional drink. At each time point, measurements were performed twice using 2D and twice using 3D ultrasound. Volumes were calculated using the ellipsoid method for 2D ultrasound. For 3D, manual tracing was performed.

Results

Sixty-two subjects were included, yielding 2,328 volume measurements. The mean age was 69 years (SD 6.6) and the median BMI was 24.3 kg/m² (IQR 22.9-28.6). The mean difference between 2D me
