Aim: To assess the reproducibility of pelvic floor biometric parameters by translabial three-dimensional ultrasound compared with the OmniView® reformatting technique. Material and methods: We performed a cross-sectional study involving 47 nulliparous women without symptoms of pelvic floor dysfunction. The hiatal area and right pubovisceral muscle width measurements were performed in the axial plane using both 3D ultrasound in the rendering mode and OmniView® techniques. To determine the occurrence of standardized error between examiners and the two sonographic methods, the paired t-test was used. The intra- and inter-observer reliability and agreement were estimated by concordance correlation coefficient (CCC) and limits of agreement, respectively. Results: We did not observe significant statistical differences among both measurements performed by the first examiner, both examiners and both methods in the assessment of the hiatal area; however, the measurements of the right pubovisceral muscle were significantly lower using OmniView®. The intra-observer reliability was good in the evaluation of all pelvic floor parameters; however, the inter-observer reliability was good only to the 3D rendering mode (CCC=0.87). The intra-observer agreement was good in the assessment of all pelvic floor parameters; however, the inter-observer agreement was found to be good only when 3DUS in the rendering mode was used (<±15%). Conclusion: Both 3D ultrasound in the rendering mode and OmniView® reformatting techniques were concordant in the assessment of pelvic floor parameters; however, the 3D ultrasound rendering in the mode demonstrated better inter-observer reliability and agreement.

We investigated whether mobile C-arm cone beam computer tomography (CBCT) could be used to measure radioulnar translation. The study was conducted on 31 Thiel-fixed intact cadaver arms. Three-dimensional scans of each wrist were carried out in pronation and supination. Four established measurement methods were used (radioulnar line, subluxation ratio, epicentre and radioulnar ratio methods) to measure radioulnar translation. The intraclass correlation coefficient for inter-observer and intra-observer reliability were excellent in three of four methods (>0.94). The reference ranges for physiological radioulnar translation were between −30% and 91% (radioulnar line method), −32% and 87% (subluxation ratio method), −40% and 23% (epicentre method), and 2% and 73% (radioulnar ratio method). Our results indicate that radioulnar translation in the distal radioulnar joint can be determined reliably using mobile C-arm CBCT. The normal values provide a basis for further experimental and clinical studies.

AbstractObjectivesA small or a large cavum septi pellucidi (CSP) during routine second trimester sonography may suggest abnormal cerebral development. Therefore, determination of CSP volume with three-dimensional (3D) ultrasound can be valuable. For this purpose, we sought to evaluate the reference ranges and measurement reliability of CSP volume by Virtual Organ Computer-aided AnaLysis (VOCAL).MethodsVOCAL software was used to calculate the CSP volume from transabdominal multiplanar datasets of 99 structurally normal fetal ultrasound examinations between 19 and 24 weeks of gestation. Linear regression was utilized to determine reference intervals for CSP volumes as a function of gestational week (GW). Agreement among three evaluators with different proficiency levels (obstetrics and gynecology resident, perinatology fellow, and perinatologist) was assessed, using intraclass correlation coefficients (ICC) and 95% confidence intervals (CI).ResultsCSP volume and gestational age was positively correlated (r2=0.383, p=0.0001), represented by the following equation: 0.058–(1.016 x GW). Interobserver agreement between perinatologist and fellow was relatively high (ICC, 0.78; 95% CI, 0.70–0.85), whereas limited ultrasound experience (resident) was associated with fair agreement with non-novice observers (ICC for resident and perinatologist, 0.50; 95% CI, 0.29–0.65 and ICC for resident and fellow, 0.57; 95% CI, 0.38–0.71).ConclusionsReference ranges of CSP volumes using VOCAL from 19 0/6 through 24 6/7 weeks of gestation were established. A first-degree model to estimate CSP volume as a function of gestational age was also constructed. CSP volumetry seems reliable when evaluated by an examiner with particular 3D sonography experience.
