“…Currently, new evaluation methods include 2D or 3D ultrasonography, which focuses on the morphologic change of the cervix using cervical volume [12-17] and a gray-scale histogram [18-22]. …”

“…The graphic representation of the gray-scale histogram illustrates the quantity, reflexivity and disposition of the 'pixels' in the specific area of interest [18]. Although the majority of previous studies measured only the anterior or posterior lips of the cervix or both with a 2D view, a study by Kuwata et al [19] assessed the differences between the anterior and posterior cervix with a gray-scale histogram.…”

“…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.

BackgroundPreterm labor (PTL) is a challenging gynecological problem that is accountable for high rates of perinatal mortality and morbidity. Low maternal serum cholesterol and progesterone levels are associated with preterm birth. Measurement of cervical length, funneling, and consistency are essential in screening for PTL. ObjectiveThe aim of the study was to show a correlation between maternal serum progesterone and cholesterol levels and cervical transvaginal gray-scale histogram at 20-25 weeks in the prediction of preterm birth in high-risk women. Patients and methodsThe study included 100 patients at high risk for PTL attending Minia Maternity University Hospital. Levels of progesterone and cholesterol were analyzed and a cervical transvaginal histogram to determine cervical glandular/stromal ratio was performed for all patients at 20-25 weeks of gestation. Results PTL occurred in 30 of 100 women. Increased incidence of spontaneous PTL was seen in patients with a short cervix and increased funneling. Serum progesterone was significantly (P = 0.001) lower in women who delivered preterm (80.6 ± 27.5) compared with women who delivered at term (116.1 ± 15.8). Also, serum cholesterol was significantly (P = 0.001) lower in women who delivered preterm (156.6 ± 35.4) than in women who delivered at term (185.6 ± 42.3). Glandular/stromal ratio was significantly lower (Po0.001) in women who delivered preterm (0.31 ± 0.04) than in those who delivered at term (0.98 ± 0.02). Conclusion Glandular/stromal ratio, serum progesterone and cholesterol levels, and transvaginal ultrasound findings can predict PTL in high-risk women. They can also be used for prevention of PTL.

Transvaginal grey scale histogram of the cervix at 20–25 weeks of pregnancy

Abstract: There are large differences in the texture of the cervical stroma and CGA on GSH allowing the objective differentiation of the two areas. The CGA/stroma ratio allows the objective assessment of the absence or presence of the CGA.
