Endovaginal ultrasound is currently the gold standard to diagnose a shorted cervical length and, by extension, assess the risk of preterm labor. The major inconvenient is that this is an invasive method of diagnosis that tends to be poorly accepted by some patients. This study aims to evaluate the accuracy of a noninvasive transperineal ultrasound cervical measurement in comparison to the endovaginal technic in 2nd and 3nd trimester pregnant women where a cervical ultrasound is indicated.
