Standardized Ultrasound Diagnosis of Nuchal Cord.

Objective: This study aims to investigate the formation factors that affect the angle of nuchal cord and explore the types of nuchal cord that exist and the process of standardized ultrasound diagnosis of nuchal cord.

Methods: Ultrasonography was performed on 707 fetuses with nuchal cord, to observe the direction of the coil, determine the type of coil, and analyze the correlation between the fetal position, placental location, and the direction of the coil with the angle of the umbilical cord.

Results: Among the 707 fetuses, those with 1 loop accounted for 89.

Meta-analysis of contrast-enhanced ultrasound for the differentiation of benign and malignant breast lesions.

Background: Contrast-enhanced ultrasound (CEUS) is a non-invasive method for the assessment of breast lesions. The accuracy of CEUS in diagnosing of breast cancer has never been systematically assessed.

Purpose: To determine the overall performance of CEUS in the differentiation of benign and malignant breast lesions using meta-analysis.
