BACKGROUND: Vestibulocochlear nerve (VCN) disorders are still one of the most challenging diagnoses due to their wide range of clinical manifestations, from hearing loss to balance dysfunction. Radiographers need to be competent in various advanced magnetic resonance imaging (MRI) techniques so that they may optimize examinations to enhance diagnostic sensitivity.
PURPOSE: This review article discusses the role of MRI in diagnosing disorders of VCN, with an emphasis on advances in imaging protocols, implications for the radiographer, and how such techniques will be integrated into clinical practice.
KEY FINDINGS: MRI, especially three-dimensional T2-weighted sequences, diffusion-weighted imaging, and magnetic resonance neurography, allows the accurate imaging of VCN pathologies beyond what was possible in traditional functional tests such as pure-tone audiometry and videonystagmography. These are essential in delineating subtle lesions, guiding clinical decisions, and enhancing patient outcomes.
CONCLUSION: Diagnosis of VCN disorders highly depends on advanced imaging techniques. Radiographers will play an important role in the optimization of imaging protocols and minimization of artifacts, thereby embracing emerging MRI approaches. Their expertise ensures accurate visualization and early detection of VCN pathologies, overcoming challenges such as patient motion and high costs. Collaboration with clinicians and radiologists remains vital for improving diagnostic outcomes and patient care.
