  • Comparison Study of Oral Ultrasound Contrast Agents with Different Echogenic for Gastrointestinal Diseases

    【摘要】 目的 探讨不同回声类型超声造影剂在胃肠疾病诊断中的价值。 方法 采用“胃窗声学造影剂”充盈检查法,用凸阵3.5 MHz探头,对2009年3-8月366名受检者行经腹壁超声检查。受检者随机分为两组:饮水者为A组,饮有回声造影剂者为B组。 结果 选择性地应用合适的造影剂,能有效地提高对胃肠疾病的超声诊断水平。【Abstract】 Objective To evaluate the application of contrast agents with different echogenic in the diseases of stomach and intestine. Methods Totally, 366 patients were included in the study from March to August 2009. Patients were randomly divided into two groups: group A (oral acoustic contrast agent) and group B (water). Contrast-enhanced Doppler sonography was performed with 3.5 MHz abdomen probe. Results Contrast agent with anechoic was good for showing iso-echoic and hyperechoic tissue.Hyperechoic contrast agent was better for showing hypoechoic changes according to its long sitting-time in stomach. Conclusion Contrast enhanced ultrasound has practical value in diagnosis of the diseases of stomach and intestine.

  • Research on the Diagnostic Value of Ultrasonography in Examining Oblique Vaginal Septum Syndrome

    【摘要】 目的 探讨超声检查对阴道斜隔综合征的诊断价值,分析超声图像特点,提高诊断率,为临床选用最佳的手术方式提供依据。 方法 回顾性分析2008年1月-2010年6月经手术确诊为阴道斜隔综合征的15例患者的临床资料及超声检查结果,总结阴道斜隔综合征的声像图特点。 结果 15例经临床确诊为阴道斜隔综合征的患者,超声诊断14例,均表现为双子宫、双宫颈、阴道或宫颈积液/血,9例左肾缺如,5例右肾缺如。误诊1例,为单子宫伴一侧附件巨大囊肿。 结论 超声具有诊断准确、简便、无创、重复性好、价格实惠等优点,对于临床诊断生殖系统畸形具有十分重要的意义,应列为首选检查方式。【Abstract】 Objective To investigate the diagnostic value of ultrasonography in examining oblique vaginal septum syndrome, analyze the characteristics of ultrasound image to improve the ultrasound diagnosis rate, in order to provide guidance for clinical surgeries. Methods We retrospectively analyzed the clinical data and ultrasound examination results of 15 patients diagnosed to have oblique vaginal septum syndrome in our hospital, and summarized their ultrasonographic characteristics. Results Among the 15 patients, 14 were diagnosed to have the disease by ultrasound examination. The ultrasound image showed a double uterus, double cervix, and vaginal or cervical fluid or blood for all the patients among whom 9 had absent left kidney, and 5 had absent right kidney. One patient was misdiagnosed to have single uterus with giant cysts on one side. Conclusions Ultrasound diagnosis is simple, noninvasive, reproducible, affordable and accurate in diagnosing. It is very useful in clinical diagnosis of reproductive system abnormalities and should be listed as the preferred way of examinations.

  • Discussion on Detailed Classification of Breast Ultrasonographic BI-RADS Category 4 Lesions

    ObjectiveTo investigate the methods and significances of the breast ultrasonographic breast imaging reporting and data system (BI-RADS) category 4 lesions divided into category 4a, 4b, and 4c, and to assess the risk of malig-nancy of lesions with BI-RADS category 4 in order to improve the accuracy of diagnosis. MethodsTwo hundred and eighty-eight breast lesions with BI-RADS category 4 confirmed by histopathology were collected. The ultrasonographic characteristics of benign and malignant lesions, containing the shape, aspect ration, margin, calcification, changes of the surrounding tissue, boundary, blood flow characteristics, internal echo, rear echo of the lesions, were comparatively anal-yzed, and the lesions with BI-RADS-US category 4 were divided into 4a, 4b, 4c according to these ultrasonographic charac-teristics and analyzed by statistics. ResultsThere were 192 malignant lesions and 96 benign lesions in the 288 breast lesions. There were statistical significances in the benign and malignant lesions with the shape, aspect ratio, margin, calci-fication, change of surrounding tissue, and boundary (P < 0.05), in other words, the proportion of these ultrasonographic characteristics were higher in the malignant lesions as compared with the benign lesions. But there were no significant differences of internal echo, rear echo, and blood flow characteristics between two lesions (P > 0.05). The positive predictive value of malignant tumor with BI-RADS category 4a, 4b, and 4c were 21.74%, 58.90%, and 91.78%, respectively, and there was significant difference (χ2=106.09, P=0.000). ConclusionsThe classification of breast lesions with BI-RADS category 4 is refined, it could more accurately assess the risk of benign and malignant breast masses. At the same time, it has an important clinical significance for diagnosis and treatment of benign and malignant breast masses.

  • Clinical Value of Yolk Sac in Diagnosis of Early Pregnancy

    【摘要】 目的 通过对早期妊娠卵黄囊的观察,探讨其在早孕超声诊断中的临床价值。 方法 2008年5月-2009年1月应用阴道超声诊断仪观察536例早孕患者卵黄囊的形态、大小及卵黄囊的数目,根据结果分为卵黄囊正常及异常组,比较卵黄囊的增长情况与妊娠预后的关系。 结果 504例正常组中,501例正常妊娠结局的卵黄囊大小从孕5~11周持续增长,此后逐渐缩小,孕12周后消失;另3例为宫外孕而中止妊娠。卵黄囊异常组32例。正常组和异常组的卵黄囊大小及形态有统计学意义(Plt;0.05)。 结论 卵黄囊超声影像学改变可作为诊断早孕及预测妊娠发展和转归的可靠手段。【Abstract】 Objective To evaluate the clinical value of yolk sac in the diagnosis of early pregnancy by observing the change of yolk sac. Methods The yolk sacs in 536 pregnant women were measured by ultrasonogaphy from May 2008 to January 2009, and the correlation of the growth condition of the normal or abnormal yolk sac with pregnancy outcome were observed. Results In the normal group (504 patients), the yolk sac size of 501 patients continued to grow from five to 11 weeks of pregnancy, then gradually reduced and disappeared after 12 weeks of pregnancy. The other three patients terminated pregnancy because of ectopic pregnancy. Thirty-two cases of abnormal yolk sac were found. The results showed the size and shape of yolk sacs were significantly different between normal and abnormal groups (Plt;0.05). Conclusion The change of yolk sacs by ultrasonography during early pregnancy can be used as a good measure to diagnosis early pregnancy and predict the development and prognosis of pregnancy.

  • 超声诊断在胆囊三角中的应用

    目的探讨B型超声测定术前急性结石性胆囊炎胆囊壁厚度与术中胆囊三角显示之间的关系。 方法将2011年7月-2012年12月42例急性结石性胆囊炎患者,按术前B型超声提示的胆囊壁厚情况分为壁厚≥4 mm组(n=17)和<4 mm组(n=25),分析胆囊三角与胆囊壁厚之间的关系。 结果42例患者术中胆囊三角可显示率为52.4%,其中胆囊壁厚≥4 mm组显示率仅为17.6%,<4 mm组显示率为76.0%,两组在术中胆囊三角分离显示率比较,差异有统计学意义(P<0.05)。随着胆囊壁厚度的增加,胆囊三角显示清晰度减低。 结论术前B型超声测定急性结石性胆囊炎胆囊壁厚,可间接提示胆囊三角显露难易程度,指导急性结石性胆囊炎患者手术时机与方法的选择,避免因胆囊三角显示不清而造成胆道损伤。
