【摘要】 目的 探讨弹性成像在甲状腺微小癌诊断中的应用价值。 方法 回顾性分析从2007年12月-2008年4月间经病理证实的10例甲状腺微小癌患者共11个病灶的超声表现。 结果 彩色多普勒超声诊断甲状腺微小癌8例8个病灶，利用弹性成像技术诊断10例10灶。传统彩色多普勒超声对甲状腺微小癌的诊断率为72.7%；利用弹性成像技术对甲状腺微小癌的诊断率为90.9%。 结论 弹性成像技术对于甲状腺微小癌是对彩色多普勒超声检查的有益的补充，能够显著提高超声对甲状腺微小癌诊断的准确性。【Abstract】 Objective To evaluate the application of US-elastography in diagnosis of thyroid microcacinoma. Methods The images of color ultrasound and ultrasound elastography from 11 lesions of 10 patients with thyroid micro-carcinoma diagnosed via histopathology between December 2007 and April 2008 were retrospectively analyzed. Results Eight patients with eight lesions were found by colour ultrasound and 10 patients with 10 lesions were observed by ultrasound elastography. The diagnosis accurate rate of ultrasonography was about 72.7% and of ultrasound elastography was about 90.0%. Conclusion US-Elastography is a beneficial addition in diagnosis of thyroid microcacinoma by colour ultrasound. It can remarkably develop the accurate rate of the diagnosis of the disease.
【摘要】 目的 分析超声对腺性膀胱炎的误、漏诊原因，探讨减少其误、漏诊的方法。 方法 回顾性分析2006年1月-2010年2月经病理证实的135例腺性膀胱炎的声像图表现。 结果 135例腺性膀胱炎患者中，超声误诊26例，误诊率19.3%，漏诊11例，漏诊率8.2%。误诊的主要原因：乳头结节型和团块型与膀胱肿瘤声像图极为相似、容易混淆，超声医师对膀胱壁各层次的观察不仔细，对病史重视不够；漏诊的主要原因：膀胱充盈不佳或不充盈，病变体积太小、位于前壁或顶部，或病变位于膀胱后壁及颈部被明显增生的前列腺、膀胱内血凝块及膀胱结石等掩盖。 结论 超声是诊断腺性膀胱炎常用方法，但存在一定的误、漏诊，改进检查方法，可减少其误、漏诊发生。【Abstract】 Objective To analyze the reasons of missed diagnosis and misdiagnosis of glandularis cystitis by ultrasonography. Methods The sonographic outcomes of 135 patients with glandular cystitis diagnosed by pathological examination from January 2006 to February 2010 were retrospectively analyzed. Results In 135 patients, misdiagnosis was in 26 with a rate of 19.3%, missed diagnosis was in 11 with a rate of 8.2%. The reasons of misdiagnosis included: the sonographic outcomes of mastoid and tuberculous conglomeration were similar to those of bladder tumour; the ultrasonographic professionals didn’t clearly observe each layer of the bladder wall, and didn’t pay enough attention to the disease history. The reasons of missed diagnosis included: the bladder was under-filled or unfilled, the size of the lesions were too small and were located at the anterior wall or the top, and the lesions were located at the posterior wall and neck of the bladder which were covered up by obvious prostate hyperplasia,and gores or stones of bladder so that the lesions could not be observed. Conclusion Ultrasonography is a usual method for diagnosing glandular cystitis,and we should ameliorate the examination to decrease the misdiagnosis and missed diagnosis.
目的 探讨甲状腺髓样癌的超声声像图特点，以提高超声诊断水平。 方法 回顾性分析2006年1月－ 2010年9月经手术切除及病理组织学证实的16例甲状腺髓样癌20个结节的超声声像图表现。 结果 20个甲状腺髓样癌结节中，结节呈低回声20个，结节内部有钙化灶者13个，结节内血流丰富者13个，合并有甲状腺乳头状微小癌1例，颈部淋巴结肿大17例。 结论 甲状腺髓样癌具有一定的超声声像图特点，了解这些特点可以提高超声对甲状腺髓样癌的诊断水平。
