【摘要】 目的 探討選擇性乳腺導管造影對溢液性乳腺腫瘤的鑒別診斷價值。 方法 回顧性分析2005年1月-2009年7月50例溢液性乳腺腫瘤資料，所有患者均行鉬靶X線平片攝影、選擇性乳腺導管造影檢查及手術病理確診。 結果 17例乳腺癌主要表現為分支導管內不規則的充盈缺損伴導管壁破壞，導管阻塞中斷、斷續征、潭湖狀充盈等征象；33例乳腺導管內乳頭狀瘤主要表現為大導管內光整的充盈缺損，導管壁多無破壞，并伴有導管擴張以及扭曲。 結論 選擇性乳腺導管造影對溢液性乳腺腫瘤診斷和鑒別診斷具有重要價值。【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.
【摘要】 目的 探索腹部淋巴結結核在多層螺旋CT（multi-layered screw CT，MSCT）掃描中CT值動態變化規律。 方法 2007年1月—2010年8月，收集經診斷性治療或診斷性活檢確診的17例患者腹部淋巴結結核，記錄腫大淋巴結數量、大小、位置，測量興趣淋巴結中心、次中心、邊緣部平掃及注藥后20、60、120、180、360 s的CT值。 結果 共檢測出腫大淋巴結269個，主要分布在肝十二指腸韌帶、門腔間隙、肝胃韌帶、腸系膜根部和腰3平面以上腹主動脈周圍，CT值（49.2±13.6） Hu；強化淋巴結215個，選擇21個興趣淋巴結，測得注藥20、60、120、180、360 s后強化區CT值分別為（67.7±15.3）、（75.2±14.6）、（76.3±18.7）、（75.6±13.4）、（72.6±17.4） Hu。 結論 腹部淋巴結結核動態CT值表明動脈期明顯強化，靜脈期及延時掃描強化值維持在動脈期水平呈平臺樣改變，反映了淋巴結結核慢性感染的病理狀態。【Abstract】 Objective To explore the changing rule of dynamic CT values for abdominal lymph node tuberculosis in multi-layered screw CT (MSCT) multiphasic scanning. Methods Between January 2007 and August 2010, 17 cases of abdominal lymph node tuberculosis confirmed by diagnosis treatment or diagnosis biopsy were retrospectively analyzed. The quantity, size and position of the lymph nodes were recorded, and CT plain scanning values of the interested lymph node center, subcenter, and the margin of the node, and the CT values 20, 60, 120, 180 and 360 seconds after drug administration were also measured. Results Enlargement was found in 269 lymph nodes which were mainly distributed in the liver duodenum ligament, the gate cavity gap, the hepatogastric ligament, the mesentery root and the nodes in retroperitoneal space above the third lumbar vertebra. The average CT value was (49.2±13.6) Hu. A total of 215 lymph nodes had strengthened manifestations, and 21 interested lymph nodes were chosen for the study. The average CT values for lymph nodes with strengthened manifestations 20 ,60, 120, 180, and 360 seconds after drug administration were respectively (67.7±15.3), (75.2±14.6), (76.3±18.7), (75.6±13.4), and (72.6±17.4) Hu. Conclusion Dynamic CT value of abdominal lymph node tuberculosis shows a strengthening in the arterial phase, and the values in the the venous phase and the delayed phase maintain at the arterial phase level, and do not change, which indicates a pathological state of chronic infection of the lymph node tuberculosis.
