Abstract:
Objective:To investigate the value of prenatal ultrasound combined with MRI in the diagnosis and differential diagnosis of fetal pulmonary sequestration.Methods: The prenatal examination data of 9 cases with pulmonary sequestration confirmed by autopsy and postnatal follow-up was analyzed retrospectively. All fetuses were examined by MR examination performed within 24 hours after ultrasound examination. The results of prenatal ultrasound and MRI were analyzed, and the results were compared with the follow up results.Results: The diagnostic accuracy of ultrasound was 77.78%(7/9), 2 cases were misdiagnosed(one case was misdiagnosed as abdominal mass and one case as pulmonary cystadenoma). The diagnostic accuracy of MRI was 100%.Conclusion: Prenatal ultrasound is the primary method for pulmonary sequestration. As the supplement, MR can display directly the location, shape, size of the lesion. There is high value in diagnosis and differential diagnosis of fetal pulmonary sequestration. The combination of ultrasound and MRI can further improve the diagnostic accuracy of the disease.
