Laryngeal carcinoma after radiation therapy: correlation of abnormal MR imaging signal patterns in laryngeal cartilage with the risk of recurrence.

Abnormal MR imaging signal patterns in cartilage may not indicate a poor prognosis in every case. Abnormal signal intensity in the thyroid cartilage combined with a tumor volume of > 5 cm3, however, appears to indicate an adverse prognosis with regard to tumor recurrence.
