“…Shortening and funnelling of the cervix was first described to be associated with the diagnosis of incompetence, however it was Andersen, et al 7 who first raised the possibility that the transvaginal sonographic measurement of CL could be used to predict a risk for preterm delivery for a significant proportion of preterm birth. Therefore, morphological measurements on ultrasound examinations have become increasingly important.…”

Introduction: Preterm birth is the leading cause of neonatal morbidity and mortality not attributable to congenital anomalies or aneuploidy. It has been shown that a shortened cervix is a powerful indicator of preterm births in women with singleton and twin gestations – the shorter the cervical length, the higher the risk of spontaneous preterm birth. Ultrasound measurements of the cervix are a more accurate way of determining cervical length (CL) than using a digital method. Background: There are three approaches that may be used to perform ultrasound measurements of the cervix; these are the transabdominal (TA), transperineal (TP) and the transvaginal (TV) approach. The TV approach is considered to be the gold standard. In women who are considered to be at a high risk of preterm birth it is now recommended that the cervix is measured at the mid‐trimester ultrasound using the TV ultrasound approach. For women considered to be at a historical low risk the TV scan is not recommended, however it has been found that many women who deliver a preterm baby have no known risk factors. Conclusion: There is contradictory evidence in the literature with regard to the correlation between TA, TP and TV measurements. This article provides an overview of these three approaches with a focus on the clinical value for the assessment of the maternal cervix.

“…Transabdominal ultrasound requires a full bladder, which may influence the results falsely 18 . Transperineal-derived images have been shown to be inadequate in more than 50% of cases, while patient acceptability was similar compared with TVS 19 , which was introduced 15 years ago in singleton and later in multiple pregnancies 9,20,21 .…”

“…Transvaginal sonography (TVS) has been used to examine the cervix for approximately 15 years 9 . It is recognized that a short cervix detected by TVS with the woman in a recumbent position is a strong predictor of SPB for both singleton and twin pregnancies, and the predictive value depends on the gestational age at detection, the cut-off value and even additional clinical symptoms 10 .…”

“…More specifically, scan methodology was considered adequate when performed as described by Heath et al 13 and Andersen et al 14 , otherwise inadequate or not stated. Briefly, the appropriate ultrasound methodology for transvaginal measurement of cervical length involves emptying the urinary bladder, placement of the probe in the anterior fornix, acquisition of a midsagittal view of the cervix and the endocervical mucosa and measurement of the distance between the triangular area of echodensity at the external os and the V-shaped notch at the internal os.…”
