摘　　要：目的分析超声联合CT检查对结节性甲状腺肿合并甲状腺癌的诊断价值。方法60例结节性甲状腺肿合并甲状腺癌患者,均行超声、CT及联合检查。比较三种方法的诊断准确率,分析超声图像表现及CT特征表现。结果病理学检查结果中有35例乳头状癌、15例滤泡状癌、10例髓样癌。超声检查与CT检查的诊断准确率比较,差异无统计学意义(P>0.05);超声联合CT检查的诊断准确率95.00%高于超声单独检查的66.67%和CT单独检查的68.33%,差异有统计学意义(P<0.05)。60例患者超声图像表现:48例表现为结节大小形态异常,纵横比≥1,蟹足状改变,后方回声减弱,界限不清;12例表现为边界清,有声晕;50例表现为回声不均匀或回声低;10例表现为结节内出血,囊实性回声;51例表现为沙粒样钙化;47例在彩色多普勒血流显像(CDFI)中显示血流丰富,多为高速高阻血流;9例表现为颈部或锁骨上可见淋巴结转移,经病理学检查后证实。60例患者CT特征表现:52例可见低密度结节,形态不均;48例增强扫描后可见不均匀强化;44例可见界限不清;40例可见蟹足样改变;45例可见颗粒状钙化灶;28例可见颈部、锁骨上淋巴结转移,并经手术及病理证实。结论超声联合CT检查可提高结节性甲状腺肿合并甲状腺癌的诊断准确率,为其治疗提供参考依据和指导。Objective To analyze the value of ultrasonography combined with CT in the diagnosis of nodular goiter complicated with thyroid cancer.Methods 60 cases of nodular goiter complicated with thyroid cancer were examined by ultrasonography,CT and combined examination.The diagnostic accuracy of the three methods was compared,and the ultrasonographic findings and CT features were analyzed.Results Pathological findings showed 35 cases of papillary carcinoma,15 cases of follicular carcinoma,and 10 cases of medullary carcinoma.There was no statistically significant difference in diagnostic accuracy between ultrasonography and CT(P>0.05).The diagnostic accuracy of ultrasonography combined with CT examination was 95.00%,which was higher than that of ultrasonography(66.67%)and CT examination(68.33%)alone,and the difference was statistically significant(P<0.05).The ultrasonographic findings of 60 patients were as follows:48 patients showed abnormal nodule size and shape,aspect ratio≥1,crab foot-like change,weakened rear echo and unclear boundary;12 cases showed clear boundary and faint sound;50 cases showed uneven echo or low echo;10 cases showed nodular hemorrhage and cystic echo;51 cases showed sand-like calcification.Color Doppler flow imaging(CDFI)showed abundant blood flow in 47 cases,mostly high speed and high resistance blood flow;lymph node metastasis was observed in the neck or clavicle in 9 cases,which was confirmed by pathological examination.CT features of 60 patients:52 cases showed hypodense nodules with uneven morphology;48 cases showed inhomogeneous enhancement after enhancement scan;44 cases showed poorly defined;40 cases showed crab footlike changes;45 cases showed granular calcification foci;28 cases showed lymph node metastasis in the neck and supraclavicular area,which were confirmed by surgery and pathology.Conclusion Ultrasonography combined with CT examination can improve the diagnostic accuracy of nodular goiter complicated with thyroid cancer,and can provide reference basis and guidance for its treat
