title: Evaluation of parotid lesions by magnetic resonance imaging.
abstract: The effectiveness of magnetic resonance (MR) imaging in the evaluation of parotid lesions was tested by scanning 21 patients with parotid masses. In 20 patients the lesion was visualized, and in 19 benign/malignant differentiation was accurately made, indicating sensitivity and specificity of .95. The deep extent of the lesions was readily assessed by MR but the facial nerve could not be identified.
