Objective Low-dose aspirin started by the end of the first-trimester is recommended for women at high-risk of preeclampsia. Algorithms combining uterine artery (UtA) pulsatility index (PI) and other biomarkers in the first-trimester are highly effective in predicting such risk. First-trimester UtA-PI is usually measured using the sagittal approach, with moderate inter-observer reproducibility. We aimed to evaluate a novel approach for first-trimester UtA-PI measurement; the transverse technique.
