Application of implantable medical devices in magnetic resonance imaging examination and clinical recommendations
Objective:To investigate the application status of implantable medical devices in magnetic resonance imaging(MRI)examination and put forward clinical suggestions.Materials and Methods:This study was a cross-sectional investigation,using convenient sampling method.Relying on the Nursing Group of Radiology Society of Chinese Medical Association,an electronic questionnaire was distributed to nurses engaged in imaging nursing from February to March 2023 by asking questions.In this study,the clinical application of MRI examination of compatible,implant material devices,implant materials,magnetic field strength,implantation time and scanning time were investigated.After data collection,Excel 2016 software was used for data analysis.Frequency and percentage(%)were used for descriptive statistical analysis of counting data.Results:A total of 227 hospitals in 28 provinces,autonomous regions and municipalities directly under the Central Government have filled in valid questionnaires.The investigation on the clinical application of nine types of implantable medical devices showed that more than 75.00%hospitals require the signature of patients or their families before examination,81.01%hospitals require the signature of clinicians who implant compatible pacemakers,and 77.85%hospitals require to carry instructions.Among them,artificial joints,cardiac stents and orthopedic internal fixators were the most allowed or partially allowed hospitals,accounting for 87.22%,86.79%and 81.05%,respectively.The number of hospitals allowed or partially allowed for MRI examination of cochlear implant was the least,accounting for 31.28%.Except for the infusion port,the proportion of other eight types of implantable medical device hospitals requiring scanning magnetic field≤1.5 T was between 64.71%and 83.15%.The proportion of limited implantation time>3 weeks was between 63.01%and 92.96%.The proportion of limited scanning time≤15 min was between 28.32%and 39.44%.Conclusions:At present,there were different clinical applications and clinical adaptation conditions of nine types of implantable medical devices in domestic hospitals.Establishing a unified and homogeneous clinical safety assessment and clinical application standard in China has certain guiding significance for clinical safety screening and judgment of nurses in imaging department.
