Abstract：Objective To compare and analyze the difference and consistency of ultrasound free anatomical imaging and MRI in the diagnosis of fetal craniocerebral malformation in the middle and late pregnancy.Methods From January 2018 to December 2021,170 patients with fetal craniocerebral malformation in the middle and late pregnancy were selected,and the prenatal ultrasound free anatomical imaging and MRI were retrospectively analyzed.The results of diagnosis of fetal craniocere-bral malformation by ultrasound free anatomical imaging and MRI were calculated,and the detection status of ultrasound free anatomical imaging and MRI examination were analyzed.The images obtained by ultrasound free anatomical imaging and MRI were evaluated.Results There was no significant difference in the diagnostic results of different types of fetal craniocerebral malformation between ultrasound free anatomical imaging and MRI(P＞0.05).The diagnostic accuracy of MRI was signifi-cantly higher than that of ultrasound free anatomical imaging,and the rate of misdiagnosis and missed diagnosis was lower than that of ultrasound free anatomical imaging(P＜0.05,P＜0.01).The sensitivity and specificity of MRI were significantly higher than that of ultrasound free anatomical imaging(P＜0.01).The qualified rate of MRI was99.41%(169/170)com-pared with 88.82%(151/170)of ultrasound free anatomical imaging(P＜0.01).Conclusion Compared with ultrasound free anatomical imaging,MRI has good accuracy,sensitivity,specificity and image qualification rate in the diagnosis of fetal craniocerebral malformation in the middle and late pregnancy,and the rate of misdiagnosis and missed diagnosis is lower,and the application effect is better.However,in clinical practice,the doctor needs to choose the appropriate diagnostic method ac-cording to the actual situation of the fetus.
