Preliminary quantitative and qualitative evaluation of contrast-enhanced ultrasonography (CEUS) in normal proliferative endometrium of infertile patients

CEUS of the normal proliferative endometrium in infertile patients mainly demonstrated homogeneous enhancement, predominantly low enhancement and isointensity, with clear boundaries between the subendometrium and myometrium, and distinct TIC characteristics. CEUS technology effectively displays the blood perfusion in the endometrium, subendometrium, and myometrium, with high sensitivity. This study provides reference ranges for the quantitative parameters of CEUS in the normal proliferative endometrium of infertility patients.
