输尿管肿瘤的影像学分析

Iconography analysis of ureter tumor

目的:探讨输尿管肿瘤的影像学特点,为临床提供正确的诊断依据。方法:收集30例输尿管肿瘤患者的影像学资料,均行CT扫描和MRI检查。结果:输尿管肿瘤的CT表现:输尿管管壁不规则增厚狭窄或管径增大,输尿管管内有软组织充盈缺损,病变向周围侵犯时,局部可见软组织肿块。增强扫描有助于清晰显示病变。CT诊断符合率86.7%。输尿管肿瘤的MRI表现为:输尿管不规则狭窄、截断和充盈缺损征,实质信号降低,肾盂、肾盏扩张积水。MRI诊断符合率93.3%。两组比较差异无统计学意义(P>0.05)。结论:螺旋CT和MRI是诊断输尿管肿瘤的重要方法。

Objective:To explore the iconography characteristics of ureter tumors and to provide correct diagnostic basis in clinical.Methods:The iconography data of 30 cases of patients with ureter tumors were collected and given CT scan and MRI. Results:The CT manifestation of ureter tumor:the ureteral wall thicken irregularly or diameter increased,there was filling defect of soft tissue in ureteral tube,local soft tissue mass were visible if the pathological changes invaded into the surrounding.Enhanced scanning helped to display the lesions clear.The diagnosis coincidence rate of CT was 86.7%.MRI manifestation of ureter tumor:the ureter had irregular stenosis,truncation and filling defect,the real signal was reduced,the renal pelvis and calyces had hydronephrosis.The diagnosis coincidence rate of MRI was 93.3%.There was no statistically significant difference between the two groups(P>0.05).Conclusion:Spiral CT and MRI were important methods for diagnosis of ureter tumor.
