多层螺旋CT薄层观察颈部淋巴结对甲状腺癌的诊断价值

目的：探讨SCT薄层观察平扫及增强图像观察颈部淋巴结对甲状腺癌的诊断价值。方法：回顾性分析45例经MSCT平扫及增强检查且手术病理证实为良、恶性占位者的颈部淋巴结CT表现,总结淋巴结大小、位置、形态,强化情况与甲状腺癌的相关性。结果：45例中37例发现淋巴结增大,占82%。其中,甲状腺癌92%（12/13）;甲状腺腺瘤79%（15/19）;结节性甲状腺增生75%（9/12）,转移瘤100%（1/1）。结论：甲状腺癌常伴淋巴结转移,MSCT薄层观察平扫及增强图像,能更好发现颈部淋巴结、显示其边缘及内部结构,对甲状腺癌的诊断及手术治疗提供有价值的帮助。

The value of multi-slice spiral CT thin-slice observation of cervical lymph node in the diagnosis of thyroid cancer

Objective: To study the valuation of multi-slice spiral CT thin-slice plain scan and enhance image observation of cervical lymph node used in the diagnosis of thyroid cancer. Methods: CT manifestations of cervical lymph node of 45 cases who were diagnosed with benign and malignant spaceoccupyinglesion by MACT plain scan, enhance inspection and pathological examination were analyzed retrospectively. The relativity between size, location, form, enhance condition of lymph nodes and thyroid cancer was summarized. Results: Thirty-seven cases (82%) were found lymph node enlargement, among them, the thyroid cancer accounted for 92%(12/13), thyroid adenoma accounted for 79%(15/19), nodules thyroid hyperplasia accounted for 75%(9/12), metastases accounted for 100%(1/1). Conclusion: Thyroid cancer often accompanies with lymph node metastasis. MSCT thin-slice plain scan and enhance image can find cervical lymph nodes easily and show the edge and internal structure effectively, which can provide the valuable help for thyroid cancer diagnosis and surgical treatment.
