The purpose of this retrospective MRI work was to evaluate the use of turbo gradient spin echo (TGSE) high resolution imaging for the detection of eighth nerve schwannomas, without injection of gadolinium. The TGSE sequence (slice thickness: 3 mm with 1.5 mm interleaving; matrix: 512) was compared with a reference sequence: T1-weighted spin echo (SE) after gadolinium injection (slice thickness: 3 mm, matrix: 256). Among 380 internal auditory meatus (IAM) explored, 34 abnormalities were detected on T2-weighted TGSE images compared with 19 on contrast-enhanced T1-weighted SE images. This new sequence has a 100% sensitivity, a 96% specificity and a 100% negative predictive value. Using a rigorous protocol for IAM analysis with the TGSE sequence, gadolinium injection may no longer be needed systematically for vestibular schwannoma screening, but might only be necessary when an abnormality or a doubt persists after TGSE. This approach allows about 20% cost reduction for each patient, a savings of 11,433 euros considering only the true negatives observed in this study.
