Abstract Objective: To explore the value of 2D and 3D ultrasound combined with MRI in the diagnosis of fetal butterfly vertebrae. Methods: The cases of fetal butterfly vertebrae diagnosed by 2D, 3D ultrasound and MRI were retrospectively analyzed, then the follow-up results were collected. Results: Thirty-six cases of butterfly vertebrae were diagnosed prenatally, of which 10 cases were complicated with other deformities. Compared with the results of postnatal follow-up, the diagnostic accuracy of 2D, 3D ultrasound and MRI were 69.4%, 94.4% and 78.8%, respectively. Conclusions: 2D, 3D ultrasound and MRI have their own advantages and disadvantages in the diagnosis of fetal butterfly vertebrae. The combination of these examinations can improve the diagnostic confidence of the disease. The butterfly vertebrae without other deformities and chromosome abnormalities has good prognosis.
