MRI results from investigation of head and neck tumors.

A comparative study between MRI and CT was done with particular reference to the head and neck regions. Compared with CT, MRI offered better tissue contrast, vascular visualization without the need for iodinated contrast media, direct coronal scanning, and a special surface coil for high spatial resolution. MRI is a promising modality for this region despite its difficulty in visualizing bone and its slightly poorer spatial resolution.
