灰阶实时超声对腮腺肿块的鉴别诊断

作者报道了经手术及病理活检证实的18例腮腺肿块灰阶实时超声显象诊断。灰阶超声对腮腺肿块的定位诊断符合率为100％,定性诊断符合率为72％(13/18)。作者并对超声诊断的临床价值及良、恶性腮腺肿瘤的超声图象特征进行了分析讨论。     

灰阶实时超声对腮腺肿块的鉴别诊断

This paper reports the ultrasonographic diagnoses in 18 cases of parotid gland masses confirmed by surgery and biopsy and pathology. The diagnostic accuracy was 100% (18/18) in the judgement in locations and was 72% (13/18) in the judgement in the nature of the disease. The clinical value of ultrasonographic diagnosis in parotid gland masses and the features of the sonographic images in benign and malignant tumors were analysed and discussed.     

灰阶实时超声对胆系结石的流行病病学调查

Gray-scale real-time ultrasound has been employed to investigate gallstone with a positive result of 553 cases out of 15,856 healthy subjects in city and countryside, the incidence being 34.88%. The feature of incidence is as follows: 1. The incidence of the simple gallbladder stone is more common than that of the other sites (male is about 81.15%, female is about 87.29%); 2. The incidence of gallstones of city residents is higher than that of the country people with significant difference statistically (P less than 0.01); 3. The incidence of gallstone in female city residents is higher than male, about 2.5:1, which shows significant difference. (P less than 0.01); 4. The incidence of gallstones in female city residents is higher than in countryside (P less than 0.01); 5. There is no significant difference in the incidence of gallstone between male and female in the countryside (P greater than 0.05); 6. There is no significant difference in the incidence of gallstones between city male and the male in the countryside (P greater than 0.05); 7. Either in the city or in the countryside, it has been shown that there is a tendency of increasing incidence of gallstone with age in both sexes (P less than 0.01). The relationship between the gallstone and the clinical symptoms has been discussed in this paper.     

灰阶实时超声对胆系结石的流行病学调查

作者报道用灰阶实时超声显象仪,对15 856例健康体检人群(包括城市和乡村)进行了胆道系统(下称胆系)结石普查,结果表明,患胆系结石者553例,总患病率为34.88‰,且有以下特点:胆囊结石最多(男、女分别为81.15％、87.29％);城市人群胆结石患病率明显高于乡村(P<0.01);城市人群中女性胆结石患病率明显高于男性,约为2.5:1(P<0.01),也明显高于乡村女性(P<0.01);乡村人群中,男、女性胆结石患病率无显著差异(P>0.05);城市与乡村的男性胆结石患病率无显著性差异(P>0.05);城市和乡村的男、女性胆结石患病率都有随年龄增加而增加的趋势,有极显著性差异(P值均<0.01)。作者还讨论了胆结石与临床症状的关系。     

γ射线吸收法测量跟骨骨矿含量

作者用γ射线吸收法骨矿分析仪扫描测量了30个成人干跟骨骨矿含量,并计算了跟骨骨矿含量与跟骨重量之间的相关系数。其结果表明,跟骨骨矿含量与跟骨重量密切相关(r=0.9617),本研究所选定的跟骨扫描部位具有方便、可信等优点,可供临床应用。     

用灰阶超声对人群中胆系结石的调查

用灰阶实时超声检查3833例健康成人,结果发现胆石患者135例,患病率为35‰;女性患病率(49‰)明显高于男性(25‰);男性40岁、女性30岁以后随年龄增长其患病率均有明显增加;单纯胆囊结石患者130例(96％)。有临床症状者52例(39％),且多为胆囊内多个小结石及胆总管内结石。
