“…Other methods are able to assess cervical biomechanical characteristics such as distensibility and tissue stiffness [30][31][32][33][34][35][36] , uterine cervix composition and optical characteristics [37][38][39][40][41][42][43] . Unfortunately, most of these methods are invasive and evaluate only a specific part of the cervix, which is an important limitation taking into account the heterogeneity of the uterine cervix structure.…”

Objectives: Quantitative texture analysis has been proposed to extract robust features from the ultrasound image to detect subtle changes in the textures of the images. The aim of this study was to evaluate the feasibility of quantitative cervical texture analysis to assess cervical tissue changes throughout pregnancy. Methods: This was a cross-sectional study including singleton pregnancies between 20.0 and 41.6 weeks of gestation from women who delivered at term. Cervical length was measured, and a selected region of interest in the cervix was delineated. A model to predict gestational age based on features extracted from cervical images was developed following three steps: data splitting, feature transformation, and regression model computation. Results: Seven hundred images, 30 per gestational week, were included for analysis. There was a strong correlation between the gestational age at which the images were obtained and the estimated gestational age by quantitative analysis of the cervical texture (R = 0.88). Discussion: This study provides evidence that quantitative analysis of cervical texture can extract features from cervical ultrasound images which correlate with gestational age. Further research is needed to evaluate its applicability as a biomarker of the risk of spontaneous preterm birth, as well as its role in cervical assessment in other clinical situations in which cervical evaluation might be relevant.

“…These modifications include a marked reduction of collagen concentration, a 2.5-fold increase in the GAG content, a significant decrease in dermatan sulfate concentrations from 41% to 15% of the total GAG content, a 12-fold increase in hyaluronate concentrations, and a marked reduction of fibronectin, all of which have been demonstrated by immunohistochemical experiments. Thus, the loss of collagen and sulfated GAGs may facilitate tension in the ripened cervix, while the significant gain in hyaluronate associated with hydration could explain the soft and swollen consistency of the cervix [20,26]. …”

“…However, these studies evaluated the cervix with a 2D level perspective and only evaluated specific parts of the cervix [18,20-22]. Therefore, these measurements may not reflect the entire cervix as 2D measurements may be inaccurate because the images are dependent on the site of observation and may not identify small changes in the tissue.…”

ObjectiveOur aim was to figure out whether volumetric gray-scale histogram difference between anterior and posterior cervix can indicate the extent of cervical consistency.MethodsWe collected data of 95 patients who were appropriate for vaginal delivery with 36th to 37th weeks of gestational age from September 2010 to October 2011 in the Department of Obstetrics and Gynecology, Korea University Ansan Hospital. Patients were excluded who had one of the followings: Cesarean section, labor induction, premature rupture of membrane. Thirty-four patients were finally enrolled. The patients underwent evaluation of the cervix through Bishop score, cervical length, cervical volume, three-dimensional (3D) cervical volumetric gray-scale histogram. The interval days from the cervix evaluation to the delivery day were counted. We compared to 3D cervical volumetric gray-scale histogram, Bishop score, cervical length, cervical volume with interval days from the evaluation of the cervix to the delivery.ResultsGray-scale histogram difference between anterior and posterior cervix was significantly correlated to days to delivery. Its correlation coefficient (R) was 0.500 (P = 0.003). The cervical length was significantly related to the days to delivery. The correlation coefficient (R) and P-value between them were 0.421 and 0.013. However, anterior lip histogram, posterior lip histogram, total cervical volume, Bishop score were not associated with days to delivery (P >0.05).ConclusionBy using gray-scale histogram difference between anterior and posterior cervix and cervical length correlated with the days to delivery. These methods can be utilized to better help predict a cervical consistency.

“…Tsoi et al, 26 examined 216 symptomatic women with singleton pregnancies and observed that a cervical length measured by transvaginal ultrasound of less than 15 mm could distinguish those at risk of delivery within seven days. Tekesin et al, 27 evaluated 68 patients with threatened preterm labor and observed that the risk of preterm delivery increased in patients with a cervical length of less than 25 mm. They also found that a quantitative ultrasound tissue characterization of the cervix was the best predictor of preterm delivery.…”
