Objective: To explore the value of three-dimensional ultrasound (3D-US) in prenatal diagnosis of fetal hemivertebra and assessment of scoliosis caused by hemivertebra. Methods: Ultrasonic data of 30 healthy fetuses in the second or third trimester and 9 fetuses with suspected hemivertebra were obtained. Comparison with radiographic findings and other data obtained after birth or induced abortion was performed. Results: In normal fetuses, the display rate of 3D-US for the coronal plane of fetal spines was 100% (30/30), of two-dimensional ultrasound was 30.00% (9/30). Among 9 fetuses with suspected hemivertebra, hemivertebra was found in 7, while mixed malformations (butterfly vertebra and hemivertebra) were found in 2 fetuses. 3D-US detected scoliosis in 8 fetuses, and the measurement results of Cobb angle with 3D-US were not statistically different compared with those of radiography (t=0.11, P=0.91). Conclusion: Three-dimensional ultrasonography is helpful to detection and evaluation on hemivertebra in developing fetus, which can provide more evidence for consultant and prognosis of fetal hemivertebra.
