摘　　要：目的比较超声与多参数磁共振成像(MRI)在舌鳞状细胞癌(TSCC)诊断中的应用价值。方法选择2016年10月至2019年10月于医院就诊并经病理确诊的TSCC患者68例,入组患者均接受超声与多参数MRI检查,比较两种检查方法对不同厚度TSCC的检出率以及诊断TSCC淋巴结转移的价值。结果68例TSCC患者均经术后病理活检证实,共发现29例患者阳性淋巴结转移。超声表现为舌呈现低回声区,边缘不光滑,内部回声呈现不均匀增强,形态欠规则;MRI表现为舌不规则软组织肿块,T_(1)WI呈现低信号或者稍低信号,T_(2)WI呈现高信号或者稍高信号,脂肪抑制像呈现为高信号或混杂信号,增强扫面后,肿瘤病灶少数呈现不均匀强化。超声检出的TSCC厚度为(6.16±1.23)mm,明显小于多参数MRI[(7.42±1.06)mm,P<0.05];超声对不同厚度TSCC检出率为92.65%(63/68),多参数MRI的检出率为73.53%(50/68),超声对不同厚度TSCC的检出率,尤其是对厚度<5mm的TSCC的检出率明显高于多参数MRI(P<0.05)。以病理结果为“金标准”,超声诊断TSCC淋巴结转移的灵敏度为75.86%,特异度为87.18%,准确性为82.35%;多参数MRI诊断TSCC淋巴结转移的灵敏度为48.28%,特异度为79.49%,准确性为66.18%,超声诊断TSCC淋巴结转移的灵敏度以及准确性明显高于多参数MRI诊断(P<0.05)。结论超声对较小厚度TSCC的检出率以及诊断TSCC淋巴结转移的价值优于多参数MRI。Objective To compare the application value of ultrasound and multiparameter magnetic resonance imaging(MRI)in the diagnosis of tongue squamous cell carcinoma(TSCC).Methods Sixty-eight TSCC patients who were treated and diagnosed pathologically in the hospital from October 2016 to October 2019 were selected.All patients received ultrasound and multiparameter MRI examination.The detection rates of the two examination methods for different thicknesses of TSCC and the value of diagnosis of TSCC lymph node metastasis were compared.Results 68 cases of TSCC patients were confirmed by postoperative pathological biopsy.A total of 29 patients were found to have positive lymph node metastasis.Ultrasound showed low tongue echo area,rough edges,uneven enhancement of internal echo and irregular shape,and MRI showed tongue irregular soft tissue masses,low or slightly low signal in T_(1)WI,high or slightly high signal in T_(2)WI and high signal or mixed signal in fat suppression image,and after enhancement scan,few tumor lesions showed uneven enhancement.The TSCC thickness was(6.16±1.23)mm by ultrasound detection,which was significantly smaller than(7.42±1.06)mm by multiparameter MRI detection(P<0.05).The detection rate of TSCC with different thicknesses was 92.65%(63/68)by ultrasound and was 73.53%(50/68)by multiparameter MRI.The detection rate of TSCC with different thicknesses showed that especially the detection rate of TSCC with thickness less than 5mm by ultrasound detection was significantly higher than that by multiparameter MRI detection(P<0.05).Taking the pathological results as the gold standard,the sensitivity,specificity and accuracy of ultrasound in the diagnosis of TSCC lymph node metastasis were 75.86%,87.18% and 82.35%.The sensitivity,specificity and accuracy of multiparameter MRI in the diagnosis of TSCC lymph node metastasis were 48.28%,79.49% and 66.18%,and the sensitivity and accuracy of ultrasound in the diagnosis of TSCC lymph node metastasis were significantly higher than those of multiparameter MRI dia
