In the past, Dr. Shin has developed a unique Sleep MRI protocol with polysomography (EEG, oral/nasal airflow, respiratory effort monitoring, etc) correlation to evaluate the dynamic airway collapse in Obstructive Sleep Apnea (OSA) patients. Utilizing custom-made MRI pulse sequences/software, he is able to perform continuous, multiplanar MR imaging in sleep apnea patients under natural physiologic sleep. Currently, Dr. Shin is evaluating the clinical utility of Sleep MRI; additional applications of sleep MRI can include further understanding the dynamics of airway collapse, development of minimally invasive OSA treatments, and evaluation/trouble shooting of existing OSA therapeutics.
