[To highlight the evidence-based medical imaging clinical appropriateness (EB-MICA��)]

The appropriate application of medical imaging is a major concern of our nation in recent years. In the year of 2020, we proposed the concept of Evidence-based Medical Imaging Clinical Appropriateness (EB-MICA^®). We preliminary evaluated the value of different kinds of medical imaging in clinical practice. A series of work had be applied in the stage of medical imaging application. It has decreased the cost of patients and medical insurance and improved the medical efficiency, providing key clues for medical policy makers objectively. It is also an important opportunity for the transformation of medical model towards the "value-based model". In the concern of appropriate medical imaging for patients with tinnitus, hearing loss and (or) vertigo, IgG4-related disease in clinical practice, experts in related academic group wrote and published three EB-MICA consensuses as reference. This work keeps promoting rational utilization of medical resource and improving the quality of clinical decision-making.
