Abstract:
Purpose To explore the feasibility of prenatal MRI as a supplementary imaging examination of fetal multicystic dysplastic kidney(MCDK),and to improve the accuracy of imaging diagnosis.Materials and Methods The MR images of 104 fetuses diagnosed as MCDK by prenatal fetal MRI in Hubei Maternal and Children's Hospital from January 2018 to December 2021 were retrospectively analyzed.The results of fetal MRI were compared with those of autopsy or postnatal surgery,ultrasound and MRI,and the diagnostic accuracy of MRI and ultrasound was compared,respectively,the advantages of MRI combined with ultrasound in the diagnosis of MCDK was also analyzed.Results Among 104 fetuses diagnosed as MCDK by MRI,there were 102 cases with MCDK and 2 cases with misdiagnoses.Amniotic fluid was obviously reduced or absent in 4 cases.Among the 102 cases of MCDK,58 cases(56.9％)were correctly diagnosed as MCDK by ultrasound,40 cases(39.1％)were identified with polycystic alterations,without diagnosed as MCDK,and 4 cases(3.9％)were misdiagnosed as other diseases(1 case with adult polycystic kidney,1 case with multiple renal cyst and 2 cases with renal absence).Conclusion Compared with prenatal ultrasound,prenatal MRI can obtain more information,especially in oligohydramnios and maternal obesity affecting the quality of ultrasound image.MRI can be used as a reliable supplementary method of prenatal ultrasound.
