This article reported 12 cases of urinary tract obeructions caused by congenital anomalies of renal ureters. Before the ultrasonic diagnosis,all cases with abeominal "mass" had been found by physical examinations. Due to the lack of typical symptoms,further diagnoses were difficult.The application of ultrasound provide the diasnoses which were proved correct after surseries. It shows that ultrasound can provide dependable evidence for diagnosis and it is of great value to clinicak practice.

Magnetic resonance fluids - imaging methodis one of the recently fast - developed techniques inMRI. It includes so - called MR cholangiopancreatog-raphy (MRCP), MR urography (MRU), MR myelog-raphy (MRM), MR inner ear imaging and MRsialography (MRS). On heavily T_2 - weighted images, very slowflow or relative stationary fluids, such as bile andpancreatic secretions, urine, cerebrospinal fluid, endolym-phatic fluid and saliva exhibit extremely high signal inten-sity, whereas surrounding solid organs and fast flowingblood are displayed as low signal intensity. Images of flu-ids - containing organs can he obtained using MR se-quences based on the long T_2 relaxation time of staticfluids. Being a safe, no contrast material required, non- invasive imaging method, magnetic resonance fluids -imaging technique can provide valuable diagnostic in-formation as an important adjunct to the conventionalimaging modalities. To some extent, it is an alterna-tive to the diagnostic endoscopic retrograde cholan-giopancreatography (ERCP), percutaneous transhepaticcholangiography (PTC), intravenous pyelography(IVP), X - ray myelography, and X - ray sialogra-phy. Nowadays, extensive researches on clinical ap-plications of this technique grow fast. It showed apromising prospects in diagnosis of some pancreaticobiliarysystem diseases, urinary tract obstruction, spinal stenosisand so on. There are some limitations in this technique,such as the spatial resolution is inferior to the conven-tional radiographs, and no therapeutic inventions can beperformed at the time of diagnosis. With continued tech-nologic refinements and further research advancements, webelieve that the magnetic resonance fluids - imaging tech-nique will have more extensive clinical applications andits proper role in imaging examination selection will beestablished.

磁共振液体成像为近年来迅速发展的磁共振成像新技术之一,是磁共振胰胆管成像(MRCP)、磁共振泌尿系成像(MRU)、磁共振椎管成像(MRM)、磁共振内耳成像及磁共振涎腺管成像(MRS)等的总称。磁共振液体成像技术主要利用静态液体具有的长T_2弛豫时间,在很重的T_2加权序列上,胆汁、胰液、尿液、脑脊液、内耳淋巴液及唾液等流动缓慢或相对停滞的液体均呈明显的高信号,而周围实质器官和快速流动的血液则表现为低信号,从而使含液体的器官显影。作为一种安全、无需造影剂、无创伤性的影像学检查手段,磁共振液体成像技术作为传统影像学检查的重要补充,可提供有价值的诊断信息,在某种程度上代替诊断性ERCP、PTC、IVP、X线椎管造影、X线涎管造影等传统造影检查。目前此项技术的临床应用研究日益广泛,在某些胰胆管疾患、泌尿系梗阻及椎管狭窄性病变等的检查中展示了良好的应用前景。尽管该技术仍有其限度,如空间分辨率较传统X线造影差,仅能作为诊断性检查而无法进行介入治疗等。但我们相信,随着成像技术的不断改进,以及研究工作的不断深入,磁共振液体成像技术将会展现出更广泛的临床应用价值,确立其在影像学检查中适当的位置。

Materials and Methods: 70 patients were examined with fast spin-echo heavily T2 weighted sequence,acquired in coronal plane.After elimilation of the unrelated parts on the images slice by slice the three dimentional raw data of the urinary tract were project into a composite image of MRU using a maximum intensity projection (MIP) algorithm. 24 patients were verified by operation and pathology, including...

Purpose: To evaluate the clinical application of MR urography(MRU)in the diagnosis of urinary tract obstruction. Materials and Methods: 70 patients were examined with fast spin-echo heavily T2 weighted sequence,acquired in coronal plane.After elimilation of the unrelated parts on the images slice by slice the three dimentional raw data of the urinary tract were project into a composite image of MRU using a maximum intensity projection (MIP) algorithm. 24 patients were verified by operation and pathology, including ureteral calculus(n=12), congenital ureteral stricture(n=4), stricture caused by chronic inflammation(n=3), polyp(n=2)and others(n=4). In one patient, both polyp and stone were found. Results: MRU provided high resolution images of urinary tract in all patients with urinary tract obstruction, The locations of urinary tract in all patients and the causes of hydronephrosis were distinctly showed. Conclusion: MRU is a noninvasive technique with excellent accuracy in the diagnosis of urinary tract obstruction. It does not require iodinated contrast material and has no ionizing radiation. MRU is a new and safe imaging technique for urinary tract obstruction. It is especially useful for patients with severe hydronephrosis whose IVP can not display the urinary tract well.

目的 :评价磁共振尿路造影(MRU)对泌尿系梗阻性疾病的临床应用价值。材料和方法 :采用快速自旋回波(FSE)重T2 加权序列对70例患者进行泌尿系冠状位扫描 ,将图像按最大强度投影(MIP)法重建出MRU图像。经手术和病理证实为尿路梗阻者24例 ,其中尿路结石12例 ,尿路先天性梗阻4例 ,输尿管炎性狭窄3例 ,炎性息肉2例(其中1例为炎性息肉伴输尿管结石) ,其他4例。结果 :各例的MRU均清晰显示梗阻的尿路 ,对肾盂积水及尿路梗阻部位显示良好 ,解剖结构清晰。结合MR与其他影像资料 ,可对梗阻作出定性诊断。结论 :MRU是无创伤的检查方法 ,不接触射线 ,不需碘对比剂 ,诊断尿路梗阻性疾病定位、定性准确 ,是一种新的安全的影像检查手段 ,尤其适用于因严重梗阻IVP显影不良的病例。
