Effect of B-mode optimization techniques on fetal bowel echogenicity using computerized image analysis.

Objectives: The purpose of this study was to provide and compare measurable parameters for normal fetal bowel echogenicity under predefined B-mode scanning presets.

Methods: Forty healthy fetuses underwent 14- to 17-week ultrasound scans, and 40 underwent 21- to 25-week scans. Sagittal, coronal, and axial fetal abdominal images were tested using predefined B-mode presets.
