PDFAbstract
Objective To analyze the application value of MRI in preoperative evaluation of acoustic neurilemomas and summarize the MRI findings. Methods 54 cases of patients with suspected acoustic schwannoms treated in our hospital from January 2011 to November 2015 were analyzed. All patients underwent MRI and CT examination. The diagnostic accordance rates in the two groups were compared. The MRI findings of acoustic neurilemomas were summarized. Results The sensitivity and accordance rate of MRI (100%) were respectively higher than those of CT (83%, 85%) (P<0.05). Conclusion MRI has high sensitivity in the diagnosis of acoustic neurilemomas. The pathologic degree can be decided through evaluating the length of internal auditory canal, which is beneficial to preoperative evaluation and the application value is great.
