中文摘要:目的 研究各种CT征象在甲状腺良、恶性病变鉴别诊断中的价值。方法 根据患者病理检查结果将84例甲状腺病变患者分为良性组46例,恶性组38例。统计分析所有患者CT扫描结果,并计算CT对恶性病变诊断的敏感度、特异性和准确性。结果 良、恶性组单发病灶者所占比例分别为17.39%和57.89%;边缘清晰者所占比例分别为63.04%和10.53%;密度均匀者所占比例分别为41.30%和36.84%;有砂砾样钙化者所占比例分别为15.22%和94.74%;强化程度低于甲状腺者所占比例分别为19.57%和84.21%;囊性病变者所占比例分别为36.96%和2.63%;伴有颈淋巴结肿大者所占比例分别为10.87%和52.63%。CT诊断恶性病变的敏感度、特异性和准确性分别为84.21%、89.13%、86.90%。结论 甲状腺病变中单发病灶、边缘模糊、有砂砾样钙化、强化程度低于甲状腺、囊实性或实性病灶、伴有颈淋巴结肿大等CT征象提示恶性病变可能性大。CT对甲状腺良、恶性病变鉴别诊断准确性高,值得临床推广应用。

Diagnostic and Differential Diagnostic Value of CT Signs for Benign and Malignant Lesions of Thyroid
Abstract:Objective To investigate the diagnostic and differential diagnostic value of CT signs for benign and malignant lesions of thyroid. Methods Eighty four patients with thyroid disease were divided into benign group which had 46 patients and malignant group which had 38 patients according to their different diagnosis confirmed by pathological examination. The CT signs were statistically analyzed by three doctors. And then doctors made a diagnosis according to the CT signs of each patient. These diagnoses were compared with pathological examination to calculate their sensitivity specificity and accuracy. Results The proportions of solitary lesion in benign and malignant group were 17.39% and 57.89% respectively. The proportions of lesion with a clear edge in benign and malignant group were 63.04% and 10.53% respectively.The proportions of lesion with uniform density in benign and malignant group were 41.30% and 36.84% respectively.The proportions of lesion with calcification in benign and malignant group were 15.22% and 94.74% respectively.The proportions of lesion with enhance degree greater than or equal to thyroid in benign and malignant group were 19.57% and 84.21% respectively.The proportions of cystic lesions in benign and malignant group were 36.96% and 2.63% respectively;The proportions of lymph node swelling in benign and malignant group were 10.87% and 52.63% respectively.The sensitivity specificity and accuracy of the diagnoses of CT were 84.21%,89.13% and 86.90%. Conclusion The solitary and solid lesion with blurry edge, calcification, lymph node swelling and enhance degree greater than or equal to thyroid is more likely to be a malignant lesion. Computed tomography is worthy of being widely applied in clinic because it has high diagnostic and differential diagnostic value for benign and malignant lesions of thyroid.
