Magnetic resonance imaging of the neoplasms involving the head

Magnetic resonance (MR) imaging is a new method for producing high quality tomographic images with improved soft-tissue definition. MR imaging is conceptually quite different from conventional imaging modalities. A number of variations in MR technique may be chosen to provide better resolution or improved specificity. Some of the current and future roles of MR in the evaluation of both cranial and extracranial neoplasms involving the head are discussed.
