  ABSTRACT: Severe acute respiratory syndrome coronavirus 2 has thoroughly reshaped the medical landscape. Much has been written and discussed of the adaptations required by this pandemic, particularly in the realm of elective medical care. While some areas of the country have, in recent weeks, seen a plateau or even a decrease in coronavirus 2019 case-burden, others remain face-to-face with significant ongoing morbidity and mortality. Furthermore, given eased restrictions across numerous states and municipalities, a widespread resurgence of the disease is not precluded. To that end, we have attempted to summarize experiences and best practices in the handling of breast imaging against the backdrop of the novel coronavirus, and we consider future directions.
