摘要: OBJECTIVE. MR imaging was prospectively correlated with pathologic findings to study whether can differentiate viable from nonviable tumor tissue in the irradiated carcinoma of tongue.SUBJECTS AND METHODS. examinations were performed after radiation therapy 21 patients tongue. All underwent either a total glossectomy or hemiglossectomy therapy. Specimens examined microscopically. Radiation changes histologically graded into four groups (I, minimal cellular changes; II, presence and partial destruction tumor; III, only cells; IV, no cells). included T2-weighted imaging, unenhanced T1-weighted dynamic contrast-enhanced imaging.RESULTS. On images, lesion hypointense, except for two histologic grade III. appeared hyperintense 12 14 pa...
