“…Since the advent of SonoAVC, several studies have been performed to test the different possibilities of this new imaging tool. This might create the impression that 2D measurements are outdated [2,7,8,9]. For example, it was investigated what the impact could be of automated follicle tracking, where volumes are measured, compared to the ‘routine' 2D ultrasound scanning of follicles.…”

“…For example, it was investigated what the impact could be of automated follicle tracking, where volumes are measured, compared to the ‘routine' 2D ultrasound scanning of follicles. It was shown that automated follicular measurements of both diameters and volumes provide a comparable but quicker assessment of follicle number and size [2,7]. However, an improvement of the clinical outcome of assisted reproductive technology could not be shown [3].…”

Aim: To investigate intra- and inter-observer variability in 2-dimensional (2D) follicular measurements among midwives sub-specialized in medically assisted reproduction (MAR), using a new 3D tool imitating real-life ovarian scanning. Methods: Six 3D ultrasound volumes from stimulated ovaries were recorded and stored on the ultrasound device(Voluson i, GE Healthcare). Two junior midwives (with 6-36 months' ultrasound scanning experience) and 5 seniors (>36 months' experience) assessed the number of follicles per ovary and the average size of each follicle ≥10 mm off-line. There were 2 time points of measurement by each midwife with a mean interval of 12.7 weeks (±10.7). Intra- and inter-observer variability in the number of follicles, the mean follicle size and the diameter of the largest follicle were investigated using the Wilcoxon signed-rank test and the Kruskal-Wallis test. Results: There was no significantintra- or inter-observer variability among midwives in the evaluation of the number of follicles, their diameter or the diameter of the largest follicle, even when juniors and seniors were compared. Conclusions: These data support the view that well-trained midwives can perform 2D follicle measurements to monitor MAR treatment in a reproducible way, and that prerecorded 3D volumes can also be used for quality control purposes.

“…Current techniques can detect follicles as small as 2 mm, and such follicles appear in the automated reports generated by Sono AVC. We included follicles of at least 10 mm as measured by calculated volume diameter for our evaluation, a cutoff that was utilized in previous investigations [19]. Patients older than 45 years or with ovarian cysts at the start of the ovarian stimulation procedure were excluded.…”

Aims: We define criteria to predict the number of mature oocytes using automated three-dimensional (3D) ultrasound follicle measurements. Methods: Fifty in vitro fertilization/intracytoplasmic sperm injection patients underwent automated 3D echographic monitoring by a single researcher following the stimulation procedure. Classic criteria for triggering oocyte maturation as defined in the literature were utilized. 3D parameters, including the follicular volume and follicle diameter calculated from the volume measurement, were related to the oocyte count, mature oocyte count and the number of observed fertilized oocytes. Results: We found that when oocyte maturation was induced, 55% of the total follicles with a diameter of at least 10 mm had a volume of at least 1.5 cm³. The number of mature eggs that were retrieved was correlated with the number of follicles observed with a volume of at least 1 cm³ or a calculated follicle diameter of at least 12 mm. Conclusion: Sonography-based automated volume count measurements of follicle volume and reconstructed follicle diameter can be used to reliably predict the number of mature oocytes.

“…In their two studies, Ata et al concluded that SonoAVC technology saves time, makes accurate measurements, and is highly reproducible. Its disadvantages are the need for post-processing and performance of occasional manual measurements [24,25].…”

Three-dimensional ultrasound (3D USG) is a fast-evolving imaging technique that holds a great potential for use in gynecology. Its sensitivity and specificity is reported to be close to 100 % for diagnosing congenital uterine anomalies, comparable with those of magnetic resonance imaging (MRI) and laparoscopy. With 3D USG, a coronal view of the uterus can be obtained, clearly outlining the external contour of the uterus and providing accurate information about the shape of the cavity. Although 3D USG may not perform well in thin endometria, combining it with saline infusion sonography (SIS) overcomes this problem. Research shows that 3D USG is more sensitive and specific than two-dimensional ultrasound (2D USG) in defining and mapping uterine lesions, such as fibroids, adenomyosis, and intrauterine synechia. In cases of suspected malignancy, 3D USG is mainly used in the initial evaluation of patients. Measuring various indices and mapping vascular architecture with 3D power Doppler have been proposed for evaluating adnexal masses. Although some studies raised hope, no consensus is reached about its use, success, and limitations. In urogynecology, translabial 3D USG is proved to be a valuable tool, as it provides instant access to the axial plane, which clearly depicts the relationship of the vagina, urethra, rectum, and the muscular pelvic floor. Studies report no significant differences between translabial 3D USG and MRI measurements for evaluation of the pelvic floor. In conclusion, adding 3D USG to routine gynecological workup can be beneficial for clinicians, as it provides fast and accurate results in a relatively cost-effective setting.
