目的 探讨胃肠道穿孔的多层螺旋CT(MSCT)表现及诊断价值。 方法 收集2010年3月-2011年3月18例经手术证实为胃肠道穿孔患者的临床及MSCT资料,回顾性分析了胃肠道穿孔及穿孔部位的MSCT表现。 结果 18例患者中,MSCT明确诊断穿孔17例,对穿孔部位准确定位11例。其中术后诊断胃穿孔4例、十二指肠球部穿孔9例、小肠穿孔3例、结肠穿孔1例、阑尾穿孔1例。MSCT表现有腹腔游离气体,肠壁周围局限性积气、腹腔积液及肠袢积液、肠壁增厚、肠腔周围脂肪间隙密度增高(条纹征)。 结论 MS CT有利于显示腹腔游离气体、胃肠道穿孔部位及其肠壁周围的变化情况,对胃肠道穿孔术前的定性及定位诊断有较明显的优势 ,可为临床提供更多有价值的诊断信息。
【摘要】 目的 探讨64层螺旋CT尿路造影在上尿路梗阻性病变中的运用及诊断价值。 方法 收集2009年12月—2011年1月132例行螺旋CT尿路造影,并确诊为上尿路梗阻病变患者资料,分析其图像特点并与手术及病理结果对比。 结果 132例患者经临床及手术病理证实,输尿管结石31例,先天异常及畸形51例,输尿管感染性病变16例,尿路肿瘤29例,外源性压迫3例,肾盂旁囊肿2例;所有患者均显示良好,与临床及病理结果基本吻合。 结论 CT尿路造影能多方位清楚显示病变内部及周围情况,可准确的显示、判断尿路梗阻的原因、性质,是一种对泌尿系疾病诊断极有价值的影像学检查方法。【Abstract】 Objective To discuss the utilization and diagnostic value of 64-slice spiral CT urography for upper urinary tract obstruction diseases. Methods We collected the clinical data of 132 patients who were diagnosed with upper urinary tract obstruction by 64-slice spiral CT urography between December 2009 and January 2011. We analyzed the imaging features and compared them with surgical and pathological results. Results Confirmed by surgical and pathological results, 132 patients included 31 cases of urethral stone, 51 cases of congenital variant and malformation, 16 cases of ureteral infection, 29 cases of tumors in urinary tract, 3 cases of extraneous compression, and 2 cases of cysts next to the renal pelvis. CT diagnosis for all cases were basically in line with clinical and pathological results. Conclusion CT urography is an extremely valuable imaging method to diagnose the diseases of urinary system. It can display lesions broadly and reveal their inner and peripheral circumstances clearly, thus can help us determine the reasons and natures of the lesions precisely.
