目的 探讨经阴道B型超声（B超）在诊断早期宫外孕中的临床应用价值。 方法 回顾分析2011年5月－2012年3月应用阴道B超与腹部B超对78例宫外孕患者进行对比检查的临床资料并回顾性分析，评价两种检查方法的临床效果。 结果 78例宫外孕患者，应用经阴道B超检查诊断准确率为97.44%，应用腹部B超准确率为61.54%，差异具有统计学意义（χ2=6.472，P＜0.05）；经阴道B超检查诊断附件包块、宫内假孕囊、心血管搏动、胚芽、盆腔积液的检出率明显高于经腹部B 超检查的检出率（P＜0.05）。 结论 阴道B超具有操作简单、快速、无副作用、无需充盈膀胱等优点，在宫外孕的早期诊断中具有绝对的优越性，为临床提供了更方便、更快捷的诊断手段，减轻了患者痛苦，提高了诊断的准确率，值得临床广泛推广和应用。
【摘要】 目的 探讨B型超声检查对联体双胎的诊断价值。 方法 回顾性分析2008年—2010年产前诊断为联体双胎的8例孕妇B型超声声像图资料，总结其声像表现。 结果 对称性联体双胎8例， 其中胸腹部联体6例， 头部联体2例。 结论 产前B型超声检查能为联体双胎的诊断提供重要临床信息，并可做出不同类型的诊断。【Abstract】 Objective To evaluate the value of B-scan ultrasound in diagnosing conjoined twins. Methods Prenatal ultrasound diagnosis of eight cases of conjoined twins from 2008 to 2010 in West China Second University Hospital was retrospectively analyzed, and their ultrasonograhical performances were summarized. Results Eight cases of conjoined twins with symmetry were diagnosed by B-scan ultrasound, including six with thoraco-omphalodidymus, and two with cephalodymus. Conclusion Prenatal ultrasound can provide important information for diagnosis of conjoined twins, and perform differential diagnosis for different types.
【摘要】 目的 探讨B型超声对肺不张的诊断价值。 方法 对2007年5月-2009年5月收治的67例肺不张患者的CT诊断与B型超声诊断进行对照、分析、总结。 结果 B型超声诊断一侧肺不张和肺叶肺不张与CT诊断符合率为94.64%，肺段型肺不张诊断符合率为54.55%。 结论 B型超声诊断可作为肺不张筛查的首选诊断方法。【Abstract】 ObjectiveT o study the diagnostic value of atelectasis by type-B ultrasonography. Methods Data of 67 cases of patients with atelectasis diagnosed by type-B ultrasonography and CT were compared, analyzed, and summarized between May 2007 and May 2009. Results The diagnosis coincidence rate which was got by comparing ultrasonography diagnosis of the one side atelectasis and pulmonary lobectomy atelectasis with CT diagnosis was 94.64%, and that of pulmonary segmental atelectasis was 54.55%. Conclusion Type-B ultrasonography can be used as the preferred screening atelectasis diagnosis.
目的 采用回顾性研究的方法，分析B型超声引导下的细针穿刺活检能否提高对甲状腺结节诊断的准确性。方法 54例患者行B型超声引导下的细针穿刺活检，另76例患者采用触诊法行细针穿刺活检，并将54例B超引导下的细针穿刺活检结果与手术结果进行比较。结果 超声引导下细针穿刺活检对可触及的甲状腺结节诊断的敏感性为63%，特异性为71%，准确性为65%，阳性预告值为100%，阴性预告值为70%。标本取材不当率为18%； 触诊法细针穿刺活检的灵敏性为47%，特异性为51%，准确性为43%，阳性预告值是54%，取材不当率为28%。B超引导下的细针穿刺活检准确性显著高于触诊法细针穿刺活检。结论 B超引导下的细针穿刺活检能提高手术前甲状腺癌的诊断。
ObjectiveTo explore the therapeutic value of ultrasound-guided minimally invasive Mammotome system for mammary glands nodules without type-B ultrasound echo. MethodsBetween May 2009 and April 2014, 95 patients with mammary glands nodules without type-B ultrasound echo accepted B-ultrasound guided mammotome rotary cutter excision. ResultsPreoperative B ultrasound showed single shot without echo in 30 cases and multiple shot without echo in 65 cases. Among the 95 cases without echo, there were 23 cases of mixed echo nodules, and 25 cases of clustered echo-free nodules. The postoperative pathological diagnosis showed non-proliferative fibrocystic changes in 78 cases, proliferative fibrocystic changes in 17 cases (including 1 case of carcinoma in situ), and 3 cases of intraductal papilloma. ConclusionUltrasound-guided minimally invasive Mammotome system is a choice for treating mammary glands nodules without type-B ultrasound echo.
