Abstract

Prognosis and treatment of Head and Neck tumours (HNT) are correctly planned if the analysis of their grading is accompanied by a careful neuroradiologic study of their spatial extension, lymph node involvement, before and after radiotherapy (RT).

CT and MRI are suitable devices for this purpose, since they can help in studying an anatomical region which is difficult to visualize with endoscopy. Aim of the present study is to evaluate the parameters to be considered staging of HNT also after therapy.

25 patients, aged between 26 and 73 years, underwent CT and MRI before and after radiotherapy, alone or associated with chemotherapy. Standard TNM classification was used. T evaluation considers spatial extension to mucosal, descending, ascending, lateral, posterior, perineural, perivascular spaces of the primary lesion; N considers side, borders and location of the involved lymph nodes; after treatment, these two parameters evaluate size reduction and iatrogenic modifications in the tumour mass and lymph nodes.
