In suspected acoustic neuroma, which imaging test is preferred?

Explanation:
MRI with gadolinium contrast is preferred because it provides superior soft tissue contrast and sensitivity to small vestibular schwannomas in the cerebellopontine angle and internal auditory canal. This allows detection and precise delineation of tumor size and its relationship to the cranial nerves and brainstem, which is essential for planning management. CT can show bony changes but is less sensitive for small intracranial tumors and has poorer soft tissue resolution. Ultrasound isn’t useful for intracranial imaging, and PET is not a first-line tool for diagnosing this benign tumor.
