Objective To systematically review the clinical value of color Doppler ultrasonic for diagnosing female breast cancer. Methods We electronicaaly searched the databases including The Cochrane Library (Issue 2, 2013), EMbase, PubMed, CNKI, WanFang Data, MedaLink ,VIP and CBM for diagnostic tests on breast cancer diagnosed with color Doppler ultrasonic vs. with pathological biopsy (golden criteria) from 1982 to the March, 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies according to QUADAS items. The Meta-DiSc software (version 1.4) was used to conduct pooling on sensitivity, specificity, positive likelihood radio, and negative likelihood radio. Heterogeneity test was performed and the summary receiver operating characteristic curve (SROC) was drawn for area under the curve (AUC). Results A total of 25 studies involving 3 274 patients were included. The results of meta-analysis showed that, SPE, SEN, +LR, −LR and DOR were (0.76, 95%CI 0.74 to 0.78), (0.80, 95%CI 0.78 to 0.82), (3.58, 95%CI 2.63 to 4.87), (0.28, 95%CI 0.22 to 0.35) and (13.76, 95%CI 8.47 to 22.36), respectively. The AUC of SROC curve was 0.865 7. Conclusion Current evidence shows that color Doppler ultrasonic has high sensitivity (80%) and high specificity (76%) in the diagnosis of high-frequency Ultrasound. The positive rate in the breast cancer group is 13.76 times as high as that in non-breast cancer, which indicates color Doppler ultrasonic has good diagnostic value for breast cancer.
目的 探讨胰腺良性微小肿瘤的术前及术中定位方法。方法 对1995年1月至2000年8月收治的12例直径lt;2 cm的胰腺良性肿瘤定位方法进行分析。结果 术前B超、CT或MRI和动脉造影的诊断敏感性分别是16.7%、40.0%和87.5%。通过术中探查发现病灶7例(58.3%),其余5例借助于术中B超定位成功4例。结论 术中B超是目前最有价值的定位手段,而且还能提供病灶更详细的资料,对顺利完成手术、减少并发症有重要作用。在定位过程中注意操作细节可提高定位诊断的成功率。
【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.
【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.
【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.
