Spiral CT examinations were performed pretherapeutically in 27 patients in whom cervical lymph node enlargement had been suspected. The M/Q quotient known from sonography and MR can also be employed in CT by means of coronary and sagittal reconstruction. This improves CT differentiation between reactively changed and metastatically infiltrated lymph nodes in tumour patients. Hence, CT diagnosis can now make use of a highly sensitive and highly specific criterion for diagnosing lymph nodes. Another diagnostic improvement is that vascular infiltrations by lymph node metastases can now be visualised or excluded more readily. Spiral CT is also suitable in tumorous and non-tumorous processes for an accurate assessment of the extension of e.g. retropharyngeal abscesses or laryngoceles.
对27例疑似颈部淋巴结肿大的患者进行了治疗前螺旋CT检查。超声和磁共振成像中已知的M/Q值也可通过冠状动脉和矢状面重建应用于CT。这提高了CT对肿瘤患者反应性改变和转移性浸润淋巴结的鉴别能力。因此，CT诊断现在可以利用一种高度敏感和高度特异的标准来诊断淋巴结。另一个诊断上的改进是，现在可以更容易地观察或排除淋巴结转移引起的血管浸润。螺旋CT也适用于肿瘤性和非肿瘤性病变，以准确评估例如咽后脓肿或喉膨出的范围。
