To explore the clinical value of ultrasound in the diagnosis of medullary thyroid carcinoma by comparing with enhanced computed tomography.
This retrospective study was performed on 62 patients with pathologically confirmed medullary thyroid carcinoma. All patients underwent ultrasound and enhanced computed tomography examinations before surgery. The findings of the pathologic examination of resected specimens were considered as gold standard and were compared with the results of these 2 methods.
There were 73 medullary thyroid carcinoma lesions and 29 benign lesions in 62 patients. In all, 55 of 73 medullary thyroid carcinoma lesions and 27 of 29 benign lesions were correctly diagnosed by ultrasound; and 45 of 73 medullary thyroid carcinoma lesions and 24 of 29 benign lesions were correctly diagnosed by enhanced computed tomography. The accuracy of ultrasound and enhanced computed tomography was 80.4% and 67.6%, respectively. There was significant difference between 2 methods ( < .05).
Ultrasound can be used to observe the location, number, size, shape, border, internal echo, calcification, and blood flow of the lesion. It is a convenient, inexpensive, and nonradiative method with higher accuracy than enhanced computed tomography.
通过与增强 CT 比较，探讨超声在诊断甲状腺髓样癌中的临床价值。
本回顾性研究纳入了 62 例经病理证实为甲状腺髓样癌的患者。所有患者均在术前接受了超声和增强 CT 检查。以切除标本的病理检查结果为金标准，并将其与这 2 种方法的结果进行比较。
在 62 例患者中，共发现 73 个甲状腺髓样癌病灶和 29 个良性病灶。超声正确诊断了 73 个甲状腺髓样癌病灶中的 55 个，正确诊断了 29 个良性病灶中的 27 个；增强 CT 正确诊断了 73 个甲状腺髓样癌病灶中的 45 个，正确诊断了 29 个良性病灶中的 24 个。超声和增强 CT 的准确率分别为 80.4%和 67.6%。2 种方法之间存在显著差异（<0.05）。
超声可以观察到病变的位置、数量、大小、形状、边界、内部回声、钙化和血流情况。它是一种方便、廉价、无辐射的方法，准确率高于增强 CT。
