The purpose of this study was to determine the value of MR imaging for the demonstration of masses in the tongue and floor of the mouth. Nine patients were prospectively examined with MR imaging after physical examination. Imaging protocol included T2 and contrast-enhanced and non-contrast-enhanced T1-weighted turbo spin-echo sequences, and the findings were compared with surgical and histopathological results. Histopathological examination revealed four squamous cell carcinomas, one adenoid cystic carcinoma, two tongue abscesses, and one chronic inflammatory change. The other case was diagnosed as hemangioma depending on clinical and imaging findings alone. In cases with squamous cell carcinoma, staging was done on the basis of MR imaging findings, and was found to be T4 in two cases, T3 in one case, and T2 in another. The primary role of MR imaging of the tongue and oropharynx is not to make a tissue diagnosis. Multiple deep biopsies are mandatory for the differentiation of other inflammatory and neoplastic lesions. Magnetic resonance imaging produces coronal and sagittal image planes to assess the volume and spread of the lesion and helps the surgeon determine the direction in which the biopsy should be performed.
本研究的目的是确定磁共振成像（MR成像）对于显示舌部和口腔底部肿物的价值。对9例患者在体格检查后进行了前瞻性MR成像检查。成像方案包括T2加权成像、对比增强和非对比增强的T1加权快速自旋回波序列，并将检查结果与手术及组织病理学结果进行比较。组织病理学检查显示4例鳞状细胞癌、1例腺样囊性癌、2例舌部脓肿和1例慢性炎症改变。另一例仅凭临床和影像学表现被诊断为血管瘤。对于鳞状细胞癌病例，根据MR成像结果进行分期，发现2例为T4期，1例为T3期，另1例为T2期。舌部和口咽部MR成像的主要作用并非进行组织诊断。对于鉴别其他炎症性和肿瘤性病变，多次深部活检是必不可少的。磁共振成像可产生冠状面和矢状面图像，以评估病变的体积和扩散情况，并帮助外科医生确定进行活检的方向。
