As part of differential diagnosis, an MRI scan may be done to check for vascular anomalies, tumors, and structural problems like enlarged mastoids. MRI and other types of scan cannot directly detect or measure age-related hearing loss.
All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
[5] [7] [8] A contrast-enhanced MRV (ATECO) scan has a high detection rate for abnormal transverse sinus stenoses. [15] These stenoses can be more adequately identified and assessed with catheter cerebral venography and manometry. [16] Buckling of the bilateral optic nerves with increased perineural fluid is also often noted on MRI imaging.
Tinnitus is commonly thought of as a symptom of adulthood, and is often overlooked in children. Children with hearing loss have a high incidence of pediatric tinnitus, even though they do not express the condition or its effect on their lives.
Quantitative MRI aims to increase the reproducibility of MR images and interpretations, but has historically require longer scan times. [123] Quantitative MRI (or qMRI) sometimes more specifically refers to multi-parametric quantitative MRI, the mapping of multiple tissue relaxometry parameters in a single imaging session. [128]
Noise-induced hearing loss can cause high-pitched tinnitus. [14] An estimated 50 million Americans have some degree of tinnitus in one or both ears; 16 million of them have symptoms serious enough for them to see a doctor or hearing specialist.
