Abstract

High resolution T2 magnetic resonance imaging (MRI) can provide exquisite detail of internal auditory canal (IAC) and cerebellopontine angle (CPA) lesions. In this retrospective case series, blinded imaging sequences were delivered to three radiologists and compared with previously archived clinical reads that were non-blinded and incorporated both T1+C and T2 sequences together. This article demonstrates high sensitivity and specificity for high resolution T2 MRI particularly with lesions >5mm. This suggests a role for high resolution T2 MRI as an initial screening sequence or as a surveillance sequence.

摘要

高分辨率T2磁共振成像（MRI）能够提供内耳道（IAC）和桥小脑角（CPA）病变的精细细节。在这个回顾性病例系列中，将盲法成像序列提供给三位放射科医生，并与之前存档的非盲法临床读片进行比较，后者结合了T1+C和T2序列。本文证明了高分辨率T2 MRI对大于5mm的病变具有高敏感性和特异性。这表明高分辨率T2 MRI可作为初始筛查序列或监测序列。
