36 patients with carcinomas of different ENT regions were investigated by means of MRI, CT and B-mode ultrasonography (US). The images were evaluated by parameters of clinical importance: tumour detectability marginal appearance, internal architecture, regional extension, and artifact degradation. The results were compared with the clinical tumour staging in accordance with the TNM system. In MRI, a multiplanar imaging of tumour extension with horizontal, frontal and sagittal sections is possible. Together with a good contrasting of the tumour against the surrounding structures, these are major advantages over CT in the imaging of carcinomas of the tonsils, the hypopharynx and the larynx. For both methods, tumours of the tongue base and the floor of the mouth are a real challenge. Lymph node metastases can be visualised with MRI, but US is the method of choice for the evaluation of cervical lymph nodes.
采用磁共振成像（MRI）、计算机断层扫描（CT）和B型超声检查（US）对36例不同耳鼻喉区域的癌症患者进行了研究。通过具有临床重要性的参数对图像进行评估：肿瘤可检测性、边缘外观、内部结构、区域扩展和伪影降解。将结果与根据TNM系统的临床肿瘤分期进行比较。在MRI中，可以通过水平、额状和矢状切面进行肿瘤扩展的多平面成像。再加上肿瘤与周围结构的良好对比，这些是在扁桃体、下咽和喉癌成像方面优于CT的主要优势。对于这两种方法，舌根和口底的肿瘤都是一项真正的挑战。MRI可以显示淋巴结转移，但超声是评估颈部淋巴结的首选方法。
