摘要
目的探讨超声与多层螺旋CT(MSCT)对甲状腺结节的诊断价值。方法选择经病理证实的甲状腺结节患者137例(162个结节),其中良性结节123个,恶性结节39个。与手术病理所见的结节边缘、钙化、囊变、包膜侵犯及颈部淋巴结等对照分析,比较术前超声与MSCT的显示正确率,及超声与MSCT的诊断符合率。结果超声与MSCT对甲状腺结节囊变、晕环及和颈部肿大淋巴结方面差异无统计学意义(P>0.05),超声对结节边缘的显示优于MSCT(P<0.05),而对于结节内钙化的显示MSCT优于超声(P<0.05)。超声与MSCT对甲状腺结节诊断的符合率均低于两者联合使用(P<0.05)。结论超声与MSCT均可较好地显示甲状腺结节,两者联合检查能显著提高诊断的符合率。
Objective To explore the diagnostic value of ultrasonography and multi - slice CT（MSCT） in thyroid nodules. Methods One hundred and thirty- seven patients （162 nodules） with thyroid nodules （including 39 with malignant tumors and 123 with benign tumors） confirmed by pathology were enrolled in the study. The appearances of MSCT and ultrasonography before operations were analyzed. The appearances of MSCT and ultrasonography, including the clean edge of nodules, calcification, cystic degeneration, infringed coated and cervical lymph nodes were compared with those of pathologic findings, and the coincidence rates of ultrasonography and MSCT. Results There was no statistically signifieant difference in cystic degeneration, ring and enlarged cervical lymph nodes of thyroid nodules between MSCT and ultrasonography （P 〉0.05）. The edge of thyroid nodules could be displayed more clearly with ultrasonography than MSCT （P 〈 0.05 ）, however, the calcification of thyroid nod- ules could be displayed more clearly with MSCT than ultrasonography （P〈 0.05）. The diagnosis coincidence rates of MSCT and ultrasonography were all lower than that in combined use of MSCT and ultramnography. Conclusions Both ultrasonography and MSCT can clearly display thyroid nodules, but combined use of ultramnography and MSCT can significantly improve the accuracy rate of diagnosis.
