【摘要】 目的 探讨选择性乳腺导管造影对溢液性乳腺肿瘤的鉴别诊断价值。 方法 回顾性分析2005年1月-2009年7月50例溢液性乳腺肿瘤资料，所有患者均行钼靶X线平片摄影、选择性乳腺导管造影检查及手术病理确诊。 结果 17例乳腺癌主要表现为分支导管内不规则的充盈缺损伴导管壁破坏，导管阻塞中断、断续征、潭湖状充盈等征象；33例乳腺导管内乳头状瘤主要表现为大导管内光整的充盈缺损，导管壁多无破坏，并伴有导管扩张以及扭曲。 结论 选择性乳腺导管造影对溢液性乳腺肿瘤诊断和鉴别诊断具有重要价值。【Abstract】 Objective To evaluate the value of selective mammary ductography in the diagnosis of breast tumours with nipple discharge. Methods The clinical data of 50 patients with breast tumours with nipple discharge diagnosed in our department form January 2005 to July 2009 were analyzed retrospectively. All patients were proved by molybdenum target mammography, selective mammary ductography and pathology. Results Seventeen patients with breast cancer’s galactographic features were mostly irregular intraductal defect with ductal wall breakage and ductal obstruction in the peripheral ducts; 33 patients with intraductal papilloma’s galactographic features were smooth intraductal filling defect with ductal wall integrity and ductal dilatation and torsion in the main ducts. Conclusions Selective mammary ductography is useful in diagnosis and differentiation of the breast tumours with nipple discharge.
目的:利用低剂量多层螺旋CT儿童序列及多平面重组(MPR)技术探索儿童鼻咽部气道大小及形态。资料及方法:回顾性性分析2005.05～2008.08来我院检查鼻及鼻咽部儿童的CT扫描图像,选择符合条件的3～14岁患儿73例,根据儿童鼻咽部腺样体生理特点分两组,一组3～7岁,二组8～14岁,分析儿童鼻咽部A值、N值及A/N值,总结鼻咽腔形态学特点。结果:3～14岁(两组)儿童正常鼻咽部气道失状位均呈镰刀形,周围脂肪间隙清晰,后缘光整连续;一组及二组A值均数分别为9.23±4.85 mm、9.56±4.74 mm;N值均数分别为19.23±3.5 mm、21.5±4.9 mm;两组A值及N值均数间没有统计学差异;A/N值范围一组为0.2～0.58,二组0.21～0.6。结论:3～14岁健康儿童鼻咽腔失状位呈弓向上的镰刀形,边缘光整,周围脂肪间隙清晰,A/N≤0.6。
