This time, the weighted F-value is 4.898, unweighted F-value is 2.957, that shows the weighted gap between class are more obvious that unweighted one, that is, the accuracy of the clustering algorithm is significantly higher than unweighted fuzzy clustering algorithm.

此时，加权的F值为4.898，未加权的F值为2.957，说明加权的类间的差距比未加权的明显，即该算法聚类准确率要明显高于未加权的模糊聚类算法。

Abstract］ objective to evaluate the distinctive clinical value of magnetic resonance urographymru）in the diagnosis of primary ureteral carcinoma.methods to compare the accuracy of diagnosis of mru with ultrasonography,urography,retrograde ureteropyelography and ct,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had mru examinations.the original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.results mru could clearly show the obstructive location of ureter.with regard to the ureteral carcinoma,accuracy of the location diagnosis was 100%.mru was superior to ulstrasonography,kub+ivp,ureteropyelography and ct we used to apply.conclusion comparing with other diagnostic imaging facilities,it has an important value in highly efficient,accurate location,safe,noninvasive and so on with mru,which can be used to show the features of primary ureteral carcinoma and has a wider scope of clinical application.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值。方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、ct(19例）的确诊率相比较。结果 mru能清晰显示输尿管的梗阻部位，定位诊断准确率为100%，梗阻病因确诊率高于b超、泌尿系造影、逆行造影和ct检查。结论与其他影像诊断方法相比较，磁共振水成像在显示原发性输尿管肿瘤特征方面具有效率高、定位准确和安全无创等重要价值，而且有更广泛的临床应用范围。

Methods Ultrasound, introvenus urogram, retrograde pyelography, CT, magnetic resonance urography and transurethral ureteropeyloscopy were performed, and the accuracy rate was evaluated.
