低剂量多层螺旋CT尿路成像在泌尿系疾病中的应用

the Application of Low dose MDCT Urinary Tract Imaging in Urinary Tract Disease

目的探讨低剂量多层螺旋CT尿路造影(CTU)对泌尿系疾病的临床应用价值。方法对36例临床拟泌尿系病变患者,使用呋塞米后,低剂量多层螺旋CT扫描后,行多平面重建(MPR)、曲面重组(CPR)及容积再现技术(VR),分析病变的原因。结果 36例泌尿系患者中,肾癌2例,肾盂肾炎3例,肾脓肿1例,输尿管结石18例、泌尿系先天畸形5例、输尿管炎症4例、输尿管癌2例、子宫肌瘤1例,所有病例均经临床或手术病理证实。结论多层螺旋CT尿路成像不仅可清楚直观显示泌尿系病变位置、大小和性质,还能显示周围的病变,有助于临床制定合理的治疗方案。

Objective To investigate low dose MDCT urinary tract imaging （CTU） to urinary tract disease clinical application value. Methods 36 cases of clinical quasi urinary tract disease patients, the use of furosemide, low dose multilayer spiral CT scan, line multiplanar reconstruction （MPR） and surface recombination （CPR） and volume reproduction technology （VR）, analysis the cause of the disease. Results 36 patients with urinary tract patients, 2 cases of renal cell carcinoma, pyelonephritis （3 cases）, renal abscess 1 cases of ureteral calculi, eighteen cases, urinary congenital malformation in 5 cases, 4 cases of ureteral inflammation, 2 cases of ureteral carcinoma, uterine fibroids in 1, and all cases were confirmed by clinical or surgical pathology.Conclusion MDCT urinary tract imaging can not only clear visual display urinary tract lesion location, size and nature, but also can show around the lesions, help clinical rational treatment.
