Pulsatile tinnitus (PT) is the subjective sensation of a pulse‐synchronous sound, most often due to a cerebrovascular etiology. PT can severely impact quality of life and may indicate a life‐threatening process, yet a timely and accurate diagnosis can often lead to effective treatment. Clinical assessment with a history and physical examination can often suggest a diagnosis for PT, but is rarely definitive. Therefore, PT should be evaluated with a comprehensive and targeted radiographic imaging protocol. MR imaging provides a safe and effective means to evaluate PT. Specific MR sequences may be used to highlight different elements of cerebrovascular anatomy and physiology. However, routine MR evaluation of PT must comply with economic and practical constraints, while effectively capturing both common and rarer, life‐threatening etiologies of PT.
