MSCT在诊断髓质海绵肾中的应用

目的:探讨MSCT容积扫描在诊断髓质海绵肾中的临床应用价值,以提高髓质海绵肾的临床诊断水平。方法:回顾性分析17例髓质海绵肾的临床表现、MSCT资料,并复习相关文献。所有患者均采用荷兰飞利浦公司Brilliance 6层CT机行容积扫描,常规行腹部平扫及肾脏3期增强扫描。结果:髓质海绵肾的MSCT表现为肾盏旁锥体内多发小斑点状结石,呈散在、簇状或扇形排列;增强扫描扩张的集合管内结石周围有对比剂充盈,无结石的扩张集合管呈条纹状或小囊状对比剂积聚,肾功能正常。结论:髓质海绵肾的MSCT表现具有特征性,多期扫描对髓质海绵肾的诊断敏感、准确,且能够作出定性诊断;容积扫描数据后处理图像直观,有利于指导临床制定治疗方案。

The application of MSCT in the diagnosis of medullary sponge kidney

Objective： To study the clinical application value of MSCT volume scanning in the diagnosis of the medullary sponge kidney and improve the clinical diagnosis of medullary sponge kidney. Methods： Analyze the clinical manifestation and imaging data of MSCT of 17 patients retrospectively, and review some articles. All patients underwent abdominal plain CT and three- phases enhanced images using Philips Brilliance 6-slice spiral CT volume scanning. Results：The manifestation of MSCT of me- dullary sponge kidney was multiple small spotted stones in the pyramid near calyces, arranged in scatter, cluster or fan. Enhanced scanning showed that contrast media fills around the stones in the expanded collecting tubes. Contrast media ac- cumulated in the shape of stripes or petal in the expanded collecting tubes without stones and the renal function was normal. Conclusion：The manifestation of MSCT in medullary sponge kidney is characteristic. Multi-phase scanning is sensitive and accurate in the diagnosis of medullary sponge kidney and it can give a qualitative diagnosis. The image is intuitive after vol- ume scanning,which is helpful to make a reasonable therapy.
