Objective: To explore the value of three-dimensional ultrasound in the diagnosis of fetal agenesis of the corpus callosum (ACC). Methods: Three-dimensional ultrasound (3D US) with tomography ultrasound imaging (TUI) mode was used in 14 fetuses with suspected ACC by two-dimensional ultrasound. The results were compared with that of MRI and 30 normal fetuses. Results: The diagnosis consequence of MRI of 8 fetuses was accord with that of ultrasound in 12 fetuses who were accepted MR examination. The accuracy of prenatal 3D US in the diagnosis of fetal ACC was 66.67% (8/12), sensitivity was 80.00% (8/10), misdiagnosis rate was 20.00% (2/10), positive predictive value was 80.00% (8/10). Conclusion: Successive and multiple sectioned observation can obtain direct and reliable evidences to diagnose fetal ACC with TUI mode of three-dimensional ultrasound without examining time extending. The image of sequential sagittal section of TUI mode of three-dimensional ultrasound is helpful to increase the detection rate of fetal ACC.
