Since staging of tumours in the region of tongue and floor of the mouth by clinical examination alone is inadequate, various imaging methods are utilized to obtain better pretreatment information. Since the value of ultrasonography for the staging of head and neck cancer is still controversial a comparative prospective study was carried out on 41 patients. A total of 49 sets of CT, US and clinical examination were correlated with surgical findings (n = 28) or with the results of extensive biopsy or long-term follow up (n = 21). Ultrasound was the most accurate modality for evaluation of tongue lesions and was able to document even small extension of tumour into the lateral pharyngeal wall. CT proved more accurate in the assessment of the extent of lesions in the parapharyngeal space and the evaluation of bony invasion.
由于仅通过临床检查对舌部和口腔底部肿瘤进行分期并不充分，因此采用了各种成像方法以获取更好的治疗前信息。鉴于超声检查对头颈部癌症分期的价值仍存在争议，对41例患者进行了一项比较性前瞻性研究。总共49组CT、超声检查及临床检查结果与手术所见（n = 28）或广泛活检结果或长期随访结果（n = 21）进行了对比。超声是评估舌部病变最准确的方式，甚至能够显示肿瘤向咽侧壁的微小延伸。CT在评估咽旁间隙病变范围及骨侵犯情况方面更为准确。
