产前MRI在胎儿中重度肾积水评估中的作用探讨
The role of prenatal MRI in evaluating fetal moderate-to-severe hydro nephrosis
摘要
Abstract
Objective Evaluate the role of prenatal MRI in judging etiology and severity of hydronephrosis.Methods 26 cases of fetal MRI images,which were screened by Ultrasound Scanning and prenatal MRI results indicate moderate to severe hydronephrosis,were collected from April 2015 to May 2017.Screening sequences include HASTE,True-FISP,T1WI and DWI sequence.Prenatal MR imaging results were compared with postpartum MR imaging and pathological results after surgery.Results 23 cases were confirmed by surgery pathology or autopsy out of 26 total cases,including 15 ureteropelvic junction obstruction cases,4 congenital megaureter cases,3 cases of congenital megaureter with duplex kidney and 1 cases of posterior urethral obstruction.The total valid diagnoses confirmed by prenatal MR are 20 cases,and the rest of the 3 cases are still in the follow-up observation.Conclusion MRI,as an auxiliary detection method of prenatal screening,can further clarify the etiology,severity and involved extent of hydronephrosis,to fill the lack of ultrasound.Also,it allows clinicians to intuitively understand the patient's condition,and provide solid clinical diagnosis and precise treatment for patients.关键词
