[Abstract] Objective: To investigate the clinical demand of medical magnetic resonance imaging (MRI) from radiologists of different grades of medical institutions in China, so as to provide reference and theoretical foundation for the development of domestic MRI equipment.Materials and Methods: The clinical MRI demand questionnaire was optimized by the panel of experts comprised of radiologists, medical engineers and statisticians using Delphi method. The survey of clinical demand was carried out online (https://www.sojump. com/) with MRI users working in different grades of hospitals in China.Results: A total of 246 valid feedbacks from 21 provinces were collected from September to November, 2018. The survey of magnetic field strength requirements showed that 1.5 T and 3.0 T MRI were mostly demanded, with the percentage of 74.2% and 77.9% respectively. Less than 5% of the participants had the demand for MRI equipment with magnetic field strength under 1.5 T 25 first-level demand indicators and 29 second-level demand indicators were extracted from perspectives of clinical diagnosis, scientific research and prospective equipment.Conclusions: The medium and high-end MRI equipment are highly demanded among MRI users. Domestic MRI equipment manufacturers should conduct product positioning and technical research and development based on the specific demands of MRI users.
