Abstract：Objective To understand the clinical demand of magnetic resonance imaging (MRI) from employees of different grades
in various regions throughout the country, so as to refine some technical indexes to reflect the clinical functionality, engineering
performance and user experience, and to provide reference for the establishment of the evaluation system for clinical MRI. Methods
The clinical MRI demand questionnaire was proposed by the joint of diagnostic radiologists, medical engineering experts and
statistics experts of our hospital by using Delphi method. The demand survey of MRI users was carried out online with randomly
selected participants. Results A total of 264 valid feedbacks from 32 cities in 16 provinces were collected from April to June in
2017. After comprehensive analysis, we found that the 1.5~3.0 T MRI had the highest demand. On the contrary, only 2.65% of
the participants had the demand for MRI equipment with magnetic field strength under 1.5 T. The percent of participants that had
demand to use ultra-high magnetic field MRI equipment (above 3.0 T) was 28.79%. In total, 72 highly demanded technical indexes
were extracted from perspectives of clinical functionality, engineering performance and user experience. Conclusion The demand
from perspectives of clinical functionality, engineering performance and user experience is quite high. It is of high demand to
consider including the 72 indexes when establishing the comprehensive evaluation system of medical magnetic resonance imaging
equipment.
