Head and neck lesions. Radiologic-pathologic correlations

Abstract

Correlating findings on imaging studies with those on histopathologic examination can define the limitations and strengths of the radiologist's imaging armamentarium. Although CT is particularly strong in identifying the character of the matrix of a head and neck lesion, MR imaging has proved superior in the mapping of most malignant neoplasms. Sometimes the combination of CT and MR imaging characteristics of a lesion may yield a specific diagnosis; however, in most instances, the radiologic appearance is sufficiently nonspecific that aspiration cytology or biopsy is required. This article reviews the effectiveness of imaging for characterizing and outlining lesions.
