Assessment of Internal Auditory Canal Tumors: A Comparison of Contrast-Enhanced T1-Weighted and Steady-State T2-Weighted Gradient-Echo MR Imaging

摘要

Although contrast-enhanced T1-weighted MR imaging is the standard of reference for diagnosing tumor in the cerebellopontine angle, high-resolution T2-weighted imaging may show more details of the seventh and eighth cranial nerve branches, resulting in more accurate tumor volume measurements. The purpose of this study was to compare two MR sequences for their ability to delineate internal auditory canal tumors.
