Abstract:
Objective To investigate the application value of ultrasound combined with MRI in the diagnosis of fetal urinary system abnormalities.Methods The clinical data of 647 cases of fetal urinary system abnormalities suspected by prenatal ultrasound were ana-lyzed retrospectively.All pregnant women underwent MRI examination within 2 days after ultrasound examination.Using pathology and follow-up as the gold standard,the accuracy and imaging features of ultrasound and MRI in detecting fetal urinary system abnor-malities were analyzed.Results Among 600 cases confirmed by pathology and follow-up,the accuracy of MRI,ultrasound and com-bined diagnosis of fetal urinary system abnormalities were 96.50％,96.67％,97.00％,sensitivity were 95.28％,96.23％,98.11％,and specificity were 96.76％,96.76％,96.76％,respectively.There were no significant differences in accuracy,sensitivity,specificity,positive predictive value and negative predictive value between MRI,ultrasound and combined diagnosis(P＞0.05).The area under the curve(AUC)of MRI,ultrasound and combined diagnosis of fetal urinary system abnormalities were 0.960,0.965 and 0.974,respectively,with no statistical significance(P＞0.05).Conclusion Compared with prenatal ultrasound,MRI also has a higher accuracy(96.50％)in the diagnosis of fetal urinary system abnormalities,and can be used as an important supplement to prenatal ultrasound.
