As state audiology associations continue to modernize and harmonize their scope-of-practice statutes, audiologists are increasingly empowered with the tools necessary to evaluate, diagnose, manage, and treat complex auditory and vestibular conditions. A critical component of this evolving scope includes the judicious ordering of radiographic imaging. Successful implementation requires a collaborative framework between audiologists and radiologists to ensure accurate diagnosis and management of comprehensive patient care.
This multidisciplinary session—led by one radiologist and two audiologists—offers an in-depth exploration of the diagnostic role of imaging in audio-vestibular medicine. The session will combine didactic instruction with practical, case-based learning to deepen attendees' understanding of when and how to incorporate imaging into clinical decision-making.
The radiologist will provide targeted instruction on a range of imaging modalities, including Magnetic Resonance Angiography (MRA), ultrasound, and plain film X-rays. These modalities will be discussed in the context of their specific contributions to the differential diagnosis of auditory and/or vestibular disorders. Attendees will develop a clearer understanding of:
- The appropriate use of Magnetic Resonance Imaging (MRI) versus MRA for evaluating inner ear and retrocochlear pathologies, including vestibular schwannomas and vascular anomalies
- The role of ultrasound in assessing vascular contributions to dizziness and other balance disorders, particularly in cases where vertebrobasilar insufficiency is suspected
- Targeted applications of plain film X-rays in otologic evaluation, including temporal bone abnormalities and ossicular chain disruptions
- Strategies to foster effective interdisciplinary communication between audiologists and radiologists to enhance diagnostic accuracy and streamline patient management
Through two case presentations presented by the audiologists, attendees will gain practical insight into how collaborative diagnostic imaging can directly inform treatment pathways and significantly improve effective and timely clinical outcomes. This session is ideal for audiologists seeking to refine their diagnostic acumen, engage more effectively with radiology colleagues, and responsibly integrate imaging into their expanding clinical toolkit.
Attendees will be able to:
- Differentiate between MRI and MRA and identify appropriate clinical indications for each in the diagnosis of auditory and retrocochlear pathologies
- Describe the role of ultrasound in evaluating vascular contributions to vestibular symptoms, including dizziness and imbalance
- Recognize the limited but targeted diagnostic applications of plain film X-rays in otologic assessment
- Apply case-based decision-making strategies to determine when imaging is warranted in audio-vestibular disorders
- Demonstrate effective interdisciplinary communication techniques to enhance collaboration between audiologists and radiologists, improving diagnostic accuracy and patient outcomes
