Ten healthy subjects and 44 patients with diseases of the tongue or oropharynx were studied with magnetic resonance (MR) imaging. Axial, coronal, and sagittal images with a thickness of 4 mm were obtained with a pixel size of 0.75 X 0.75 mm on a 256 matrix. Nineteen of the patients underwent computed tomography (CT). Nine of those patients later had surgery, and the specimens were obtained for organ sectioning. These three studies as well as clinical history and physical examination findings were correlated. MR imaging was equal to or better than CT in those patients having both examinations. However, neither CT nor MR allowed recognition of histologic features or detection of microscopic spread of disease. Direct coronal and sagittal imaging planes on MR imaging allowed visualization of intrinsic tongue musculature, not possible with CT; this was important in recognizing subtle tumor extension. For these reasons, MR is the imaging method of choice for studying diseases of the tongue and oropharynx.
对10名健康受试者和44名患有舌部或口咽疾病的患者进行了磁共振（MR）成像研究。在256矩阵上，获取了厚度为4毫米、像素大小为0.75×0.75毫米的轴向、冠状和矢状图像。19名患者接受了计算机断层扫描（CT）检查。其中9名患者随后接受了手术，并获取了标本用于器官切片检查。将这三项研究以及临床病史和体格检查结果进行了关联分析。在同时接受两种检查的患者中，MR成像与CT成像效果相当或优于CT。然而，CT和MR都无法识别组织学特征或检测疾病的微观扩散。MR成像上的直接冠状和矢状成像平面能够显示舌固有肌肉组织，而CT则无法做到；这对于识别细微的肿瘤扩展很重要。基于这些原因，MR是研究舌部和口咽疾病的首选成像方法。
