单纯经腹部超声检查与联合经阴道超声检查对子宫腺肌病的诊断价值分析

open access: yesZhongguo shiyan zhenduanxue, 2014
目的探讨联合经阴道超声检查与单纯经腹部超声检查对子宫腺肌病的诊断价值。方法选取2009年6月至2013年6月间在汕头大学医学院第一附属医院妇科收治的术后病理证实为子宫腺肌病患者228例作为研究对象,进行回顾性分析,比较联合经阴道超声检查与单纯经腹部超声检查对子宫腺肌病的诊断符合率及诊断价值,同时分析两种检查的诊断特点。结果①联合经阴道超声检查组的诊断符合率明显高于单纯经腹部超声检查组(P0.05)。结论联合经阴道超声检查及单纯经腹部超声检查对于子宫腺肌病均有较高诊断价值 ...

The diagnostic value of elastography and ultrasound contrast in papillary thyroid microcarcinoma [PDF]

open access: yes
目的 评估弹性成像与超声造影(CEUS)两种检查技术对鉴别诊断甲状腺微小乳头状癌(TMC)的价值。方法  对常规超声检测出且定性困难的73例80个甲状腺微小结节进行弹性成像及CEUS检查,所有结节均经手术病理证实。比较两种检查方法的准确性。结果 80个结节中CEUS诊断正确率为85.0%(68/80),其中6例TMC误诊为良性病变,6例良性结节误诊为TMC;弹性成像5分法诊断正确率为92.5%(74/80),其中3例TMC误诊为良性结节,3例良性结节误诊为TMC。性成像诊断甲状腺微小癌的敏感性94.0%,

乳腺导管内癌的超声表现与病理对照研究

open access: yesZhongguo shiyan zhenduanxue, 2010
目的探讨超声检查对乳腺导管内癌的诊断价值。方法对38例乳腺导管内癌患者进行常规二维高频超声及彩色多普勒超声检查,观察其二维声像图特征及血流特点,并经手术后病理证实,将超声检查结果与病理结果对照分析。结果乳腺导管内癌超声图像包括三个类型(1)实性肿块型;(2)囊实混合性回声型;(3)导管扩张型。结论常规二维高频超声及彩色多普勒超声检查对乳腺导管内癌的检出有重要的诊断价值,但由于缺乏特异性,需联合其他影像检查方法。
