摘　　要：目的 比较甲状腺乳头状癌（PTC）的磁共振（MRI）与超声（US）影像学特征,对比分析两者的特征显示.方法 收集2015年1月至2016年4月在江苏大学附属人民医院手术并经病理证实的PTC患者86例,分析所有PTC病灶的回声/信号、边缘、形态、纵横径比（A/T）、0微钙化以及颈部转移淋巴结,对上述结果进行比较.结果 86例PTC患者中,A/T≥1（MRI检出率62.8％;US检出率41.9％）和颈部转移淋巴结（MRI检出率88.0％;US检出率56.0％）两者特征差异均有统计学意义（χ^2=7.551,P=0.009;χ^2=6.349,P=0.025）;病灶边缘、形态在MRI和US两者特征显示方面差异均无统计学意义（P=0.724,P=0.316）.结论 MRI在评价PTC的A/T和颈部转移淋巴结方面优于US.Objective To compare the image features of magnetic resonance imaging （MRI） and ultrasound （US） for papillary thyroid carcinoma（PTC）.Methods From January 2015 to April 2016,86 consecutive patients underwent surgery and pathologically confirmed PTCs in the People ＇s Hospital Affiliated to Jiangsu University were selected.All patients received neck US and MRI examination before thyroid surgery .For each case,the US and MRI features emphasized included the echogenic /signal,margin,shape,anteroposterior to transverse diameter ratio （A/T）, microcalcifications and lymph node metastasis .Statistical analysis was performed using the χ^2test.Results In the comparison of US and MRI features,A/T≥1（41.9%in US and 62.8%in MRI） and lymph node metastasis（88.0%in MRI;56.0%in US） demonstrated statistically significant differences （χ^2=7.551,P=0.009;χ^2=6.349,P=0.025）,and no significant differences were observed in the margin ,shape（P=0.724,P=0.316）.Conclusion The MRI features of PTCs included A/T and lymph node metastasis was superior to US .
