基于多学科协作的检查准备在提升心脏磁共振检查效率中的应用研究OA

Objective To evaluate the application value of multidisciplinary team(MDT)-based examination preparations in cardiac magnetic resonance(CMR)examinations and propose new strategies to improve CMR ex-amination efficiency.Methods The department of Medical Imaging,in collaboration with the departments of Car-diology,Cardiovascular Surgery,and Cardiology Outpatient Clinic,established an MDT-based CMR examination preparation protocol.A non-concurrent controlled trial was conducted,recruiting 132 patients via convenience sampling who underwent CMR examinations at the Affiliated Hospital of Zunyi Medical University between August 2024 and July 2025.Participants were assigned to either the control group(n=66),which received standard exam-ination preparation,or the intervention group(n=66),which underwent MDT-based preparation.The primary outcome was scanning time,and the secondary outcomes included the no-show rate,examination success rate,re-peat scanning,and image quality assessed on a 4-point scale,in order to compare examination efficiency and image quality between the two groups.Results The scan time in the intervention group(34.68±5.09)min was signifi-cantly shorter than that in the control group(43.69±8.77)min.The no-show rate in the intervent ion group(1.52％)was lower than that in the control group(12.12％),and the examination success rate(96.92％)was higher than that in the control group(84.48％);the differences were statistically significant(P＜0.05),and the proportion of patients with repeated scans due to poor breath-holding or patient motion was lower than that in the control group(P＜0.05).In terms of image quality,the intervention group scored higher than the control group in cardiac anatomical imaging and first-pass myocardial perfusion imaging(P＜0.05),while there were no significant differences between the two groups in cine imaging scores for cardiac function or late gadolinium en-hancement imaging scores for myocardial viability(P＞0.05).Conclusion MDT-based examination preparation is effective in improving both the efficiency and image quality of CMR examinations.
