[Comparison of magnetic resonance imaging findings with postoperative histopathologic results in laryngeal cancers].
OBJECTIVE
We compared the findings of magnetic resonance imaging (MRI) with histopathologic results in laryngeal cancer.


METHODS
Twenty-five patients (24 males, 1 female; mean age 58 years; range 24 to 80 years) were evaluated preoperatively by MRI with regard to involvement of the thyroid cartilage, anterior commissure, vocal cords, sinus pyriformis, subglottic region, and prelaryngeal soft tissues. The findings were compared with those of histopathologic examination.


RESULTS
The highest accuracy was found in the detection of invasion to the prelaryngeal soft tissue (92%). The accuracy of MRI was 84% for the anterior commissure, 80% for vocal cords, 76% for the thyroid cartilage, and 72% for sinus pyriformis and the subglottic region.


CONCLUSIONS
Magnetic resonance imaging proved to be useful in the preoperative evaluation of laryngeal cancers.
