Background: The aim of the study was to determine the usefulness of CT and MR imaging in the preoperative evaluation of neoplasms of the craniofacial region. Material/Methods: The material consisted of 36 cases of primary and recurrent neoplasms of the craniofacial region. All the patients were treated surgically. CT and/or MR imaging was done in every patient for preoperative evaluation of soft tissue infiltration, destruction of bone structures, and metastasis of lymph nodes of the head and neck. The results of these imagings were compared with surgical evaluations and microscopic examination of postoperative specimens. Results: Both CT and MR imaging have high accuracy in evaluating soft tissue infiltration. CT imaging is much better than MR in evaluating bony destruction. MR imaging is better in evaluating recurrent tumors, in which CT has very low specificity. MR imaging is the only method for evaluating infiltration of the central nervous system. Conclusions: The authors propose the following diagnostic algorithm: CT imaging for initial evaluation before treatment, MR imaging in suspected cases of infiltration of the central nervous system, and MR imaging in recurrent tumors after surgical and radiation treatment.
