目的：通过对30例超声诊断为先天性尿路畸形的胎儿进行二维/三维超声及MRI检查，探讨胎儿MRI诊断尿路异常的准确性。胎龄18~36周。43%的妇女处于中期妊娠。结果：双侧常染色体隐性遗传性多囊肾病8例，单侧常染色体隐性遗传性多囊肾病1例，肾集合系统扩张8例，肾发育不全3例，双侧多囊肾增大5例，单侧增大多囊发育不良肾4例，肾发育不良1例。MRI改变超声诊断6例，增加信息4例。3例MRI改变了患者的治疗方法。核磁共振检查证实了20例胎儿的超声诊断。1例肾功能衰竭患者超声检查优于MRI检查。伴发肾外异常9例(30%)。MRI诊断准确率为96%。死亡率达56%。结论：胎儿MRI可作为超声诊断不明或可疑胎儿尿路异常的补充手段。(C)2014年埃及放射和核医学学会。
Purpose: To detect the accuracy of fetal MRI in diagnosing urinary tract anomalies in comparison with ultrasonographic findings and fetal outcome.Methods: We examined 30 fetuses with sonographically suspected congenital urinary tract anomalies by 2D/3D ultrasound and MRI. The gestational age range was 18-36 weeks. 43% of the women were in the second trimester. The diagnosis was confirmed by postnatal ultrasound, cystogram and biopsy in born babies and autopsy in still born or abortus fetuses.Results: We found different urinary tract anomalies including: bilateral autosomal recessive polycystic kidney disease (n = 8), unilateral autosomal recessive polycystic kidney disease (n = 1), dilated collecting system (n = 8), renal agenesis (n = 3), bilateral enlarged multicystic dysplastic kidneys (n = 5), unilateral enlarged multicystic dysplastic kidney (n = 4) and renal dysplasia (n = 1). MRI changed the US diagnosis in 6 cases and added information in 4 cases. MRI changed the patient's management in 3 cases. MRI confirmed US diagnosis in 20 fetuses. Ultrasound was superior to MRI in one case of renal failure. Associated extrarenal anomalies were detected in 9 cases (30%). MRI showed 96% accuracy in diagnosis. Mortality rate reached 56%.Conclusion: Fetal MR imaging may be used as a complementary modality to US in diagnosing inconclusive or equivocal fetal urinary abnormality.
