Approximately half of head and neck carcinomas arise from the oral cavity. Imaging plays an essential role in the preoperative evaluation of oral cavity carcinomas. MR imaging is particularly advantageous in the evaluation of the oral cavity, with better depiction of the anatomy in this region and reduction of dental artifacts compared with CT. MR is also the preferred imaging modality for the evaluation of bone marrow invasion and perineural tumor spread, which are findings critical for treatment planning. Advanced MR imaging techniques may potentially better delineate true tumor extent, determine lymph node metastases, and predict treatment response.
大约一半的头颈部癌起源于口腔。影像学在口腔癌的术前评估中起着至关重要的作用。磁共振成像（MR成像）在口腔评估中具有特别的优势，与CT相比，它能更好地显示该区域的解剖结构并减少牙科伪影。MR也是评估骨髓侵犯和神经周围肿瘤扩散的首选成像方式，这些发现对治疗方案的制定至关重要。先进的MR成像技术可能会更好地描绘肿瘤的真实范围，确定淋巴结转移情况，并预测治疗反应。
