Small glottic tumors are generally visualized by laryngoscopy and no imaging is used because thus far most imaging modalities have insufficient resolution to detect them. Here we demonstrate that with sequence and setup optimization both 3T and 7T MRI can have sufficient resolution to capture small structures around the larynx. The images obtained in 2 patients yielded new information to the head and neck physician concerning the preferred choice of treatment.
