Abstract The differential diagnosis of adnexal masses still constitutes a major clinical challenge. B-mode ultrasonography is the most used imaging technique and it is the base for this differential diagnosis with acceptable results in terms of sensitivity but a relatively high false positive rate for predicting ovarian cancer. The role of pulsed Doppler remains controversial and seems to be not reproducible in clinical practice. In the last years, a new technology such as 3D ultrasound—both morphology and 3D Angio power Doppler—has become available for discriminating between benign and malignant ovarian tumors. In this article I aim to review critically recent literature of this topic.

Abstract Recently, many researches suggested that 2D US is insufficient for defining the true sagittal plane of uterine cervix. When the cervix is bent or curved, it is difficult to get a perfect sagittal section but rather mid oblique image by 2D US. Only 3D US allows us to evaluate the cervix in the coronal section and reproduce images in many cut. Coronal section of the cervix is especially useful in evaluating cervical funneling. Diagnosing internal orifice dilatation, asymmetrical, flattened or fissure-like cervices is possible. 3D US favors a more detailed study of cervical anatomy and biometry than 2D US. Cervical evaluation by 3D multiplanar sections can be added in the screening for preterm labor. Three-dimensional (3D) imaging combined with power Doppler, theoretically provides the possibility to assess the volume and quantify the power Doppler signal in the whole target organ, whereas, information from 2D US on vascularization and blood flow is restricted to a single subjectively chosen 2D plane. The measurement of cervical indices is reproducible and may be used in clinical practice and research to determine the changes of the cervical morphology and vascularization in pregnancy. Consequently, further studies of 3D ultrasound imaging of the cervix in pregnancy and clinical correlations to obstetrical events are required for better understanding the physiology and functional pathophysiology of the cervix during pregnancy.

Abstract Objective To analyze the interobserver and intraobserver reproducibility of the visualization and continuity of the juncional zone (JZ) by three-dimensional (3D) ultrasound in infertile women, and to evaluate the sociodemographic, hormonal, and structural factors that influence these assessments. Methods A prospective study conducted at the Assisted Reproductive Technology Unit of Hospital Senhora da Oliveira, in the city of Guimarães, Portugal. Transvaginal 3D ultrasonography was performed, and 2 volumes were generated per case. Two observers who were blinded to each other's work analyzed these volumes, choosing the best coronal section. Four months later, one of the observers performed the same methodology. The JZ visualization was classified as optimal, satisfactory, and unsatisfactory, and the JZ continuity, as continuous and discontinuous. The interobserver and intraobserver agreements were analyzed. The influence of hormonal, structural, and sociodemographic factors on the JZ was evaluated. Results In total, 65 women were included in the present study. The interobserver reproducibility was substantial for JZ visualization and continuity (k = 0.635 and 0.753 respectively), and the intraobserver reproducibility was very good for JZ visualization and continuity (k = 0.884 and 0.816 respectively). Trilaminar endometrial pattern was associated with optimal JZ visualization (p = 0.012). The increase of 1 unit in the level of serum estradiol represents a 9.9% decrease in the odds of unsatisfactory visualization of the JZ (odds ratio [OR] = 0.9; 95% confidence interval [95%CI] = 0.814–0.996; p = 0.042). Endometriosis increases the odds of unsatisfactory visualization by 24 times (OR = 23.7; 95%CI = 1.262–437.057; p = 0.034). The prevalence of discontinuous JZs was of 60%. Myomas and endometriosis were associated with discontinuous JZs (p = 0.034 and 0.016 respectively). Conclusion The assessment of JZ visualization and continuity by 3D ultrasound is reproducible enough to be used in the clinical practice.

Background: Differential diagnosis of an eccentrically located sac includes interstitial pregnancy, true cornual pregnancy and angular pregnancy which may all look similar on 2D (two dimensional) ultrasound. Interstitial pregnancy is associated with a higher maternal mortality and needs to be differentiated from true cornual pregnancy and angular pregnancy. This paper is an illustration of the role of 3D (three dimensional) ultrasound in differential diagnosis and management of the three entities.Methods: 2D and 3D ultrasound findings were analyzed in 10 cases of eccentrically located sac. The role of 3D ultrasound in differentiating the three entities had been evaluated.Results: The presence of an eccentrically located gestation sac with incomplete or asymmetric myometrial tissue less than 5 mm in thickness on 2D and the coronal sections obtained from 3D scans were used for diagnosis of interstitial pregnancy in three cases. 2 cases of angular pregnancy were diagnosed based on the finding of sac located in one of the lateral angles of the uterus with broad based connection to the endometrium. 2 cases of cornual pregnancy one intrauterine in a bicornuate uterus and the other in a rudimentary horn has been described. One heterotopic pregnancy and two other cases where a cornual fibroid mimics interstitial pregnancy is also illustrated.Conclusions: The role of 3D ultrasound in differentiating the three entities and the key findings in obtaining the precise diagnosis are emphasized. Routine usage of 3D ultrasound in all cases of eccentrically located gestational sac is recommended.
