In the evaluation of space-occupying lesions of the oropharynx it is necessary to perform modern imaging methods, such as magnetic resonance imaging additionally to clinical and endoscopical methods. 126 patients were examined using T1-weighted (TR = 500 ms, TE = 25 ms) and T2-weighted (TR = 3000 ms, TE = 25/90 ms) spin-echo-sequences before and after i.v. application of Gd-DTPA. Superficially growing lesions of stage T1 could not be delineated from isointense mucosa. The preoperative staging of T2-T4 lesions can be markedly improved by using T1- and T2-weighted sequences in combination with Gd-DTPA. MR imaging with Gd-DTPA is recommended as the primary diagnostic tool for diagnosing lesions in the region of the oropharynx.
在评估口咽占位性病变时，除临床和内镜检查方法外，还需要采用现代成像方法，如磁共振成像。对126例患者在静脉注射钆喷酸葡胺前后分别使用T1加权（TR = 500 ms，TE = 25 ms）和T2加权（TR = 3000 ms，TE = 25/90 ms）自旋回波序列进行检查。T1期浅表生长性病变无法与等信号黏膜区分开来。联合使用T1加权和T2加权序列以及钆喷酸葡胺可显著改善T2 - T4期病变的术前分期。推荐使用钆喷酸葡胺的磁共振成像作为诊断口咽区域病变的主要诊断工具。
