| 内容記述タイプ | Abstract | |||||||||||||
| 内容記述 | Methods: The use of 3D power Doppler ultrasonography (3D-PDUS) for maternal orbital perfusion, together with virtual organ computer-aided analysis (VOCAL) histogram analysis, was carried out in 33 pregnancies between 25 and 40 weeks of gestation, including 18 cases of normal pregnancy (control) and 15 cases of gestational diabetes. The 3D power Doppler indices, such as the vascularization index (VI), flow index (FI), and vascularization FI (VFI), were calculated in both orbits of the individual group. The average value of each index for the two orbits was evaluated for further investigation. Both inter and intraobserver agreements of 3D-PDUS were examined. | |||||||||||||

| 内容記述 | Results: In the Bland–Altman test, the mean percentage difference and 95% limits of intra and interobserver agreements for VI, FI, and VFI were 0.0803% (7.3417, -7.181) and -0.6823% (10.8095, -12.1742), -0.4816% (6.0624, -7.0256) and 0% (9.0746, -8.8384), and 0.0058% (2.6937, -2.6821) and -0.2892% (3.8910, -4.4694), respectively. The correlation for all three 3D-PD indices, that is, VI, FI, and VFI, was higher than 0.75 (0.7832–0.9749). The VI, FI, and VFI levels between control and GDM pregnancies did not change significantly. | |||||||||||||

| 内容記述 | Conclusion: Our findings suggest that MOVS, which was assessed using 3D-PDUS and VOCAL histogram analysis, can offer fresh perspectives on observing maternal orbital perfusion in both healthy and dysfunctional pregnancies. | |||||||||||||
