本文分析了6992例患者CT检查结果,总结出现代CT检查的特点,即:1.60岁以上年龄组病例较多,新生儿占一定比例;头颅及腹部病例较多。2.中青年组阳性率低。胸部及骨骼系统阳性率最高。3.腹部增强明显多于其他部位。4.急诊病例较多。同时本文剖析了形成以上特点的原因,并从社会学和专业发生角度提出了CT检查的全面质量管理对策;1.加强社会责任;2.提高医疗行政管理质量;3.提高医务人员整体素质;4.强化CT室QC小组职能;5.完善医疗科研体制;6.重视急救医学;7.合理有效地应用CT检查技术

Purpose: For promoting the CT diagnostic accuracy of ovarian tumors. Materials and Methods: 37 surgical pathologic proved ovarian tuniors with their CT images in 28 cases were analysed retrospectively including CT specificities of cystic, solid, cystsolid and the related accompanied changes. The localization and cell determination of benign and malignant nature of the ovarian tuniors were also discussed. Results: The multiple times CT scans with different intervals can differentiate rather big ovarian tuniors...

Purpose: For promoting the CT diagnostic accuracy of ovarian tumors. Materials and Methods: 37 surgical pathologic proved ovarian tuniors with their CT images in 28 cases were analysed retrospectively including CT specificities of cystic, solid, cystsolid and the related accompanied changes. The localization and cell determination of benign and malignant nature of the ovarian tuniors were also discussed. Results: The multiple times CT scans with different intervals can differentiate rather big ovarian tuniors with extra-ovarian tumors. 80% of cystic masses were proved as benign while 87.5% solid masses as malignant, simultaneously the distribution of benign and malignant percentages among cyst-solid masses were 57.14% and 42.86% respectively. The differential diagnosis of benign and malignant ones in preoperative wrong diagnostic and atypical CT finging cases can be further promoted by analysing the shape contour, the proportion between cyst and solid content of the masses together with CT manifestations ascites and changes of nearby organs. Conclnsion: CT scan can determine the localization, benign, and malignant nature of the ovarian tuniors.

目的:提高卵巢肿瘤CT诊断的正确性。材料和方法:回顾28例37个经手术病理证实卵巢肿瘤CT资料,分析肿块本身CT特征(囊性,实性,囊实性),及其伴同变化。讨论良、恶性卵巢肿瘤的定位与定性诊断。结果:全腹部,大间距,多次的CT检查技术可对较大的卵巢肿瘤与卵巢外肿块作出鉴别。囊性肿块80%为良性,实性肿块87.5%为恶性,而囊实性肿块的良、恶性分别为57.14%与42.86%。结合肿块外形轮廓、囊实性成分比例、伴发的腹水及邻近脏器变化等CT表现可对本组术前误诊病例及CT表现不典型者作出良、恶性鉴别。结论:CT检查可对卵巢肿瘤的定位及良、恶性作出定性诊断。

Purpose: This essay gave an analytic review of the correct diagnosis of carcinoma of theampulla on the basis of CT imaging. Materials and Methods: We found 15 patients withpathologically proven carcinoma of the ampulla. All the patients underwent CT examinationsusing high - resolution scanners (GE 9800 or Elscint 2400). The pancreas were scannedpost - contrast at contiguous sections with slice thickness and width of 5mm. Results: CTfindings of the 15 patients were classified as follow: 1) Tumor masses in the...

Purpose: This essay gave an analytic review of the correct diagnosis of carcinoma of theampulla on the basis of CT imaging. Materials and Methods: We found 15 patients withpathologically proven carcinoma of the ampulla. All the patients underwent CT examinationsusing high - resolution scanners (GE 9800 or Elscint 2400). The pancreas were scannedpost - contrast at contiguous sections with slice thickness and width of 5mm. Results: CTfindings of the 15 patients were classified as follow: 1) Tumor masses in the head of thepancreas were demonstrated in 7 cases;2)Filling defects in the duodenal lumen were found in8 cases;3)The dilation of common bile ducts as well as sudden termination in its lower por-tion were found in all 15 cases. In 11 patients, dilations of the gall bladders and the intra-hepatic bile ducts were noted;4)Dilations of pancreatic ducts were demonstrated in 9 cases.Ampullary carcinoma can be divided into three types according to the sites on CT images,i .e.1 )tumor mass in the pancreatic head, 2)mass in the vicinity of the duodenal papilla, 3)mixedtype. Couelusion: Improving the CT scanning systems and techniques are necessary for thebenefit of early and accurate detection of ampullary carcinoma.

目的:回顾分析壶腹癌的CT表现,提高其诊断正确性.材料和方法:收集经CT检查后手术病理证实壶腹癌15例.全部病例均经GE9800或Elscint2400高分辨CT机行增强扫描,层厚、层距为5.0mm.结果:15例壶腹癌CT表现为1)胰头钩突肿块7例;2)十二指肠腔内充盈缺损8例;3)15例胆总管显著扩张合并下端截断性阻塞,同时合并肝内胆管、胆囊扩张11例;4)胰管扩张9例.根据壶腹癌占据部位在CT上提出分型:l)胰头钩突肿块型;2)十二脂肠乳头型;3)混合型.结论:改进CT检查技术,对早期诊断及提高壶腹癌诊断正确率有益.
