Abstract: Objective To explore the application value of standardized nursing in multi-tracers imaging of nuclear medicine department. Methods  One hundred and ten patients who underwent positron emission tomography/computed tomography (PET/CT) and positron emission tomography/magnetic resonance imaging (PET/MRI) with various tracer imaging techniques at the Department of Radiology and Nuclear Medicine,Xuanwu Hospital,Capital Medical University from June 2020 to November 2020 were selected as the study subjects. According to the random number table method,the subjects were divided into an observation group and a control group. The control group received routine care,while the observation group received standardized care on the basis of routine care. The Self Rating Anxiety Scale (SAS) score and satisfaction survey score of two groups were compared.  Results  All 110 subjects successfully completed the examination process of tracer injection,image acquisition,and post acquisition observation,without any adverse events. After confirmation by clinical doctors,the obtained images met the diagnostic requirements. There was no statistically significant difference in gender and age between the two groups (P>0.05). The SAS score of the observation group was lower than that of the control group (t=16.310,P<0.01), but the nursing satisfaction score was higher than that of the control group (t=4.348,P<0.01). Conclusion  The standardized nursing in nuclear medicine multi-tracers imaging can reduce patients' anxiety,improve nursing satisfaction,ensure smooth completion of examinations within a limited time window,and obtain high-quality images.
