64层螺旋CT在甲状腺乳头状癌诊断中的临床价值

Clinical value of 64-slice spiral CT in the diagnosis of papillary thyroid carcinoma

目的探讨64层螺旋CT对甲状腺乳头状癌的诊断价值。方法回顾分析32例经术后病理证实的甲状腺乳头状癌的CT检查影像学资料,并加以总结。结果 32例甲状腺乳头状癌平扫及增强扫描病灶密度低于周围肌肉组织及甲状腺组织。主要CT表现为密度不均32例,边界不清19例,不规则钙化9例,不规则坏死5例。结论螺旋CT是诊断甲状腺乳头状癌的有效方法,能清晰地显示周围结构关系,发现甲状腺肿瘤外侵与否,对临床术前分期及治疗方案的制定都具有重要意义。

Objective To investigate the clinical value of 64-slice spiral CT in the diagnosis with papillary thyroid carcinoma （PTC）. Methods CT findings with papillary thyroid carcinom in 32 cases were analyzed and sum- marized. All the cases had been confirmed by pathology after operation. Results The malignant lesion showed lower density than that of peripheral muscular and thyroid gland tissue on plain CT scan and enhancement scanning in 32 cases. CT finding showed uneven density in 32 cases, unclear border in 19 cases, irregular calcifications in 9 cases and irregular necrosis in 5 cases. Conclusion Spiral CT scan is an effective method for the diagnosis of papillary thyroid carcinoma. It can clearly show their relation with adjacent structures, help to find whether thyroid neoplasm invades the surrounding tissue, and thus is of great clinical significance for the clinical classification preoperatively and the formulation of treatment strategies.
