Abstract:
Objective:To evaluate the value of the preoperative T staging of laryngeal and hypopharyngeal cancers by MRI at high field strength(1.5T).Methods:The MRI data of 36 cases of primary laryngeal or hypopharyngeal cancers were retrospectively staged,and compared with the clinical and postsurgical pathologic staging.Results:The accuracy of staging in each T stage of laryngeal and hypopharyngeal cancers was:T1:92%;T2:86%;T386%;T4:100% by MRI vs.T1:100%;T286%;T3:57%;T4:22% by clinic/laryngoscope.The total accuracy of MRI and clinic/laryngoscope respectively was 92% vs 69%.P＜0.05.Conclusion:MRI can correctly depict the original tumors site and invasion extension of laryngeal and hypopharyngeal cancers by comparing T1WI and T2WI with multiplanar,consequently improve the accuracy for staging significantly.
