Study On The Accuracy Of Magnetic Resonance Imaging In Diagnosing Fetal Pulmonary Cystic Disease

Objective: 1.To explore the accuracy of magnetic resonance imaging in diagnosis of fetal pulmonary cystic diseases,mainly congenital pulmonary airway malformation,pulmonary sequestration,bronchiogenic cysts and the characteristics of magnetic resonance imaging.2.Evaluation of fetal lung development and prediction of postnatal quality of life.Methods: Retrospective analysis of the magnetic resonance images that prenatal diagnosis of pulmonary cystic disease in 86 fetuses from January 2014 to June 2017.focusing on the fetal lung lesions signal,blood supply,and successful follow-up to birth.The SPSS22.0 software was used to process the data and the four-grid table method was used to calculate the accuracy of magnetic resonance in evaluating fetal pulmonary cystic disease.The kappa value of consistency analysis was used to compare the diagnostic difference between magnetic resonance examination results and Pathological results(P < 0.05).Results:86 fetuses were diagnosed as congenital pulmonary cystic disease,49 of them were congenital pulmonary tract malformation,32 were pulmonary isolation and 5 were bronchogenic cysts.64 cases were followed up after postpartum operation,including 28 cases of congenital pulmonary tract malformation,26 cases of pulmonary sequestration,8 cases of bronchogenic cyst,1 case of mediastinal cyst,1 case of congenital pulmonary tract malformation and 1 case of pulmonary sequestration.In 4 cases,spontaneous reduction was found in prenatal reexamination,while no change was found in 1 fetus.Conclusion: Prenatal magnetic resonance imaging has important clinical value in the diagnosis of fetal pulmonary cystic disease.Prenatal magnetic resonance imaging can clearly show the location of the lesion,the types of lesions,and all aspects of the situation of mediastinal displacement and adjacent lung tissue compression.
