Abstract:
Objective To compare the diagnostic value of prenatal ultrasound with magnetic resonance imaging(MRI)in the abnormalities of fetal urinary reproductive system,and explore the value of combining prenatal ultrasound and MRI in diagnosis of fetal urinary and reproductive system abnormalities.MethodsTwenty-seven fetal abnormalities in urinary reproductive system detected by prenatal ultrasound received MRI examination within 24 hours after ultrasound,confirmed by autopsy or clinical follow-up.The results of prenatal ultrasound and MRI were analyzed retrospectively.Results Ultrasound,MRI,autopsy or after birth,postpartum follow-up confirmed 27 cases of Genitourinary system anomalies,including 2 cases of hydronephrosis,renal agenesis in 6 cases,14 cases of renal cystic disease,renal fusion in 3 cases,1 case of renal tumors,ovarian cyst in one case of crown .Fetal ultrasound can diagnose the majority of the genitourinary system anomalies (25/27),MRI can diagnose fetal anomalies of 26 cases of genitourinary system.Conclusion Ultrasound could diagnose the majority of fetal abnormalities in urology reproductive system accurately.However,combining ultrasound and MRI could establish more precise estimation in urology reproductive system,such as the level of obstruction of urinary system in hydronephrosis,the pulmonary hypoplasia secondary to urology system abnormalities,and location of cyst in the renal parenchyma or in the renal capsule.
