甲状腺疾病螺旋CT诊断的临床价值

目的　探讨CT在甲状腺疾病诊断中的价值。方法　分析经穿刺活检及手术病理证实的70例甲状腺病变的螺旋CT表现。结果　甲状腺炎性病变15例:其中弥漫性改变7例,5例叶肿大伴局限性病变,钙化2例,其余无肿大。增生病变2 2例:其中Grave病3例,为弥漫性改变并肿大;结节性增生19例,并囊变16例,钙化9例。甲状腺腺瘤16例(单发14例,多发2例) :其中12例有囊变,6例伴有钙化,所有瘤灶均有可强化的完整包膜。甲状腺癌17例:其中甲状腺癌伴结节增生10例,14例有钙化,5例有囊变。CT发现颈淋巴结转移并钙化8例,淋巴结有明显强化,囊变内壁有结节。结论　甲状腺疾病检查应以CT平扫加增强扫描为主。并强调全面综合分析。其CT影像对治疗和预后都有指导意义。

The clinical value of spiral TC diagnoses on patients with thyroid

Objective To study the clinical value of spiral CT on thyroid diagnoses. Methods The expressions of spiral TC in 70 patients with thyropathy confirmed by aspiration biopsy and operation pathology. Results There were 15 cases of thyroid inflammatory pathological changes, including 7 cases of diffuse changes, 5 cases of thyroid tumescence accompanied with limited pathological changes, 2 calcified cases, and the rest were without tumescence. There were 22 cases of hyperplasia pathological changes, including 3 cases of thyroiditis Grave’s Disease-diffuse changes with tumescence; 19 cases of nodosa hyperplasia, 16 cases of vesicle changes and 9 calcified cases. There were 16 thyroid adenoma cases (14 individual and 2 multiple), including 12 cases of vesicle changes, 6 cases with calcification. There were intensive integrity envelopes in the tumor areas. There were 17 cases of thyroid cancer, including 10 cases of thyroid cancer with nodosa hyperplasia, 14 cases of calcification and 5 cases of vesicle changes. CT detected 8 cases of lymphonodi cervicales transfer accompanied with calcification-obvious intensified lymph gland and nodosa in the wall of vesicle. Conclusion It is recommended that combined CT flat scanning and contrast enhancement scanning in thyroid examination plus aggregate analysis. The CT images are of directive functions in treatment and prognoses.
