Evaluation of NMR versus CT for parotid masses: a preliminary report.

Twelve patients with various parotid masses were prospectively studied by both nuclear magnetic resonance (NMR) imaging and intravenously enhanced computed tomography (CT). These imaging techniques were then correlated with the disease process and clinical relevance of both forms of imaging assessed. Our results suggest high resolution, spin-echo NMR offers several advantages over CT, and is likely to become the preferred method of evaluating a parotid mass.
