Abstract:
Objective To compare and analyze the diagnostic value of prenatal ultrasound and MRI in fetal thoracic abnormalities, as well as the advantages and disadvantages, respectively, and to explore the clinical value of the combined use in diagnosing fetal thoracic abnormalities.Methods The prenatal ultrasound and MRI images of total 94 cases with thoracic abnormalities were analyzed retrospectively.All the patients received MRI exams within 2 days after the preliminary ultrasound diagnosis of abnormalities.All cases were confirmed by autopsy or postnatal follow-ups.Results 94 cases of thoracic abnormalities included 48 cases of cystic adenoma abnormalities, 33 cases of bronchopulmonary sequestration, 10 cases of diaphragmatic hernia and 3 cases of primary pulmonary hypoplasia.The diagnosis coincidence rate of ultrasound was 82.98% (78/94), while the combined use was 93.62% (88/94).There were statistical differences between the combined use and single ultrasound examination in detecting fetal thoracic abnormalities(P<0.05).Conclusion Both ultrasound and MRI could diagnose fetal thoracic abnormalities well and had its own advantages and disadvantages.The combined use of ultrasound and MRI could improve the sensitivity and specificity of prenatal diagnostic accuracy and have a better advantage in diagnosing fetal thoracic abnormalities.
