This study aimed to test the intra- and interobserver agreement of a proposed image-quality scoring system to quantify the quality of gynecological transvaginal ultrasound (TVS) images, which could be used in clinical practice and AI tool development.</p><p><strong>Methods: </strong>A proposed scoring system to quantify TVS image quality was created following a review of the literature. This system involved a score of 1-4 (2 = poor, 3 = suboptimal and 4 = optimal image quality) assigned by a rater for individual ultrasound images. If the image was deemed inaccurate, it was assigned a score of 1, corresponding to 'reject'. Six professionals, including two radiologists, two sonographers and two sonologists, reviewed 150 images (50 images of the uterus and 100 images of the ovaries) obtained from 50 women, assigning each image a score of 1-4. The review of all images was repeated a second time by each rater after a period of at least 1 week. Mean scores were calculated for each rater. Overall interobserver agreement was assessed using intraclass correlation coefficient (ICC), and interobserver agreement between paired professionals and intraobserver agreement for all professionals were assessed using weighted Cohen's kappa and ICC.</p><p><strong>Results: </strong>Poor levels of interobserver agreement were obtained between the six raters for all 150 images (ICC, 0.480 (95% CI, 0.363-0.586)), as well as for assessment of the uterine images only (ICC, 0.359 (95% CI, 0.204-0.523)). Moderate agreement was achieved for the ovarian images (ICC, 0.531 (95% CI, 0.417-0.636)). Agreement between the paired sonographers and sonologists was poor for all images (ICC, 0.336 (95% CI, -0.078 to 0.619) and 0.425 (95% CI, 0.014-0.665), respectively), as well as when images were grouped into uterine images (ICC, 0.253 (95% CI, -0.097 to 0.577) and 0.299 (95% CI, -0.094 to 0.606), respectively) and ovarian images (ICC, 0.400 (95% CI, -0.043 to 0.669) and 0.469 (95% CI, 0.088-0.689), respectively). Agreement between the paired radiologists was moderate for all images (ICC, 0.600 (95% CI, 0.487-0.693)) and for their assessment of uterine images (ICC, 0.538 (95% CI, 0.311-0.707)) and ovarian images (ICC, 0.621 (95% CI, 0.483-0.728)). Weak-to-moderate intraobserver agreement was seen for each of the raters with weighted Cohen's kappa ranging from 0.533 to 0.718 for all images and from 0.467 to 0.751 for ovarian images. Similarly, for all raters, the ICC indicated moderate-to-good intraobserver agreement for all images overall (ICC ranged from 0.636 to 0.825) and for ovarian images (ICC ranged from 0.596 to 0.862).

We aimed to describe fetuses with growth restriction and transient oligohydramnios in which a congenital intrahepatic portosystemic shunt (CIPSS) was noted during follow-up.</p><p><strong>Methods: </strong>This was a retrospective study of all fetuses diagnosed with growth restriction and transient oligohydramnios during a 5-year period in a large tertiary referral center. Our routine evaluation of growth-restricted fetuses includes monitoring of estimated fetal weight, assessment of biophysical profile, Doppler imaging, thorough examination of the umbilical-portal system and evaluation of cardiac function using fetal tricuspid annular plane systolic excursion (f-TAPSE). We compared these parameters before and after the resolution of the oligohydramnios using descriptive statistics and the Wilcoxon signed-rank test for paired non-parametric variables. During the surveillance of fetuses with transient oligohydramnios, we noted the appearance of a CIPSS and followed up such cases after birth.</p><p><strong>Results: </strong>A total of 2144 women with a singleton pregnancy with suspected fetal growth restriction were referred to our center between January 2018 and December 2022. In 12 fetuses, oligohydramnios was evident upon initial assessment, and a CIPSS was diagnosed with normalization of amniotic fluid level. The median gestational age at diagnosis of growth restriction and oligohydramnios was 25 (range, 21-30) weeks. The estimated fetal weight was at the 1^st percentile in 10/12 fetuses. The median amniotic fluid index was 5 (range, 2-5) cm at the initial appointment and improved significantly to 13 (range, 11-20) cm following the shunt diagnosis (P = 0.002). Among fetuses with f-TAPSE data available, the f-TAPSE increased significantly from 4.0 (range, 3.0-5.0) mm before the diagnosis of CIPSS to 8.0 (range, 5.0-9.4) mm following the diagnosis (P = 0.043). The median gestational age at delivery was 36.3 (range, 30.8-38.4) weeks. In nine (75%) fetuses, the diagnosed shunt was left portal to left hepatic vein. Neonatal follow-up revealed spontaneous shunt resolution within 30 months in all newborns. One newborn required embolization owing to suspected shunt, however, no shunt was detected during the procedure.</p><p><strong>Conclusions: </strong>The development of CIPSS in growth-restricted fetuses with oligohydramnios appears to improve hemodynamic status as evidenced by normalization of amniotic fluid index and increase in f-TAPSE.

OA pulsatility index (PI), first peak systolic velocity (PSV1), second peak systolic velocity (PSV2) and peak systolic velocity ratio (PSV ratio), calculated as PSV2/PSV1, were measured twice in each eye by the same observer. UtA-PI was also measured twice on each side by the same observer. Maternal hemodynamic assessment was undertaken using an ultrasonic cardiac output monitor (USCOM 1A). Pearson's and Spearman's rank correlation coefficients were used to assess the correlations between variables, and Bland-Altman plots were used to evaluate the intraobserver reproducibility of OA Doppler indices.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Of 194 women invited to participate in the study, 169 were eligible for inclusion, of whom 16 were excluded following an obstetric ultrasound scan and a further three owing to inadequate or incomplete OA or UtA Doppler assessment, leaving 150 women in the final analysis. Log UtA-PI had a weak correlation with both OA-PI (r = -0.19 (95% CI, -0.34 to -0.03), P = 0.021) and OA-PSV ratio (r = 0.31 (95% CI, 0.15-0.45), P &lt; 0.001). The correlation between gestational age and OA-PI was non-significant (r = 0.14 (95% CI, -0.03 to 0.29), P = 0.097), and that between gestational age and OA-PSV ratio was weak (r = -0.23 (95% CI, -0.38 to -0.07), P = 0.004), as opposed to the strong correlation between gestational age and UtA-PI (r = -0.68 (95% CI, -0.76 to -0.58), P &lt; 0.001). No strong correlations were observed between OA-PI or OA-PSV ratio and maternal hemodynamic indices. The correlations were unaltered by adjustment for maternal age and body mass index. The intraobserver reproducibility of OA-PI and OA-PSV ratio in the same eye was high. The correlation between the right and left eyes was moderate for OA-PI (r = 0.63 (95% CI, 0.53-0.72), P &lt; 0.001) and strong for OA-PSV ratio (r = 0.81 (95% CI, 0.75-0.86), P &lt; 0.001).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;OA-PI and OA-PSV ratio had a weak or no correlation with UtA-PI and maternal hemodynamic parameters, meaning that they can be used as independent predictors for pre-eclampsia. Gestational age had no clinically relevant effect on OA-PI and OA-PSV ratio, suggesting that these indices could be measured without adjustment at any time between 11 and 23 weeks' gestation. OA Doppler indices had high intraobserver reproducibility and were strongly correlated between the right and left eyes. © 2025 The Author(s).
