Transvaginal sonography of the cervix has emerged as a useful window into preterm parturition. Cervical sonography allows measurements of cervical length (CL), which can aid clinicians in identifying women at risk for preterm birth. The use of transvaginal assessments of CL can assist in the triage of patients with possible preterm labor. Recent studies also support the use of CL measurements as a means of determining appropriate candidates for cerclage placement and progesterone supplementation to reduce the risk of premature birth, further highlighting the importance of this modality in modern obstetric management.
经阴道宫颈超声检查已成为了解早产情况的一个有用窗口。宫颈超声检查可测量宫颈长度（CL），这有助于临床医生识别有早产风险的女性。经阴道评估宫颈长度可辅助对可能早产的患者进行分诊。近期研究还支持将测量宫颈长度作为确定合适的宫颈环扎术和补充孕酮候选人的一种方法，以降低早产风险，这进一步凸显了这种检查方式在现代产科管理中的重要性。
