Abstract: The purpose of this paper is to explore the influence of MRI on CT scanning technology and diagnosis in primary hospitals, and to implement the optimization scheme to improve the detection rate of lesions. With the application of advanced MRI scanning technology and concept, reasonable order, standardized scanning and flexible diagnosis, 4250 patients were strictly prepared for examination, standard positioning and scanning parameters were adjusted. CT image quality was improved, the scanning symmetry rate was up 66%, scanning wild foreign body removal and gastrointestinal tract preparation rate increased of 69%, breathless training and reduced motion artifact by 65%. The original image reading rate, image quality score increased by 65% in the past schemes, and 92 patients with CT rare diseases were detected. The optimal scheme implemented by our hospital can effectively promote the standardized operation of grassroots technicians, optimizes CT scanning technology, and improves image quality.
