  • Radiology Rounds Video: July 2016

    In the July 2016 issue of Radiology Rounds, listen to Efren Flores, MD, Thoracic Imaging staff radiologist discuss social determinants that affect patient care in radiology. Missed appointments result in delayed diagnosis and treatment, which adversely affect care. Therefore, it is better to regard these events as “missed care opportunities” (MCOs) and look into the reasons why they occur to mitigate the problem.
