Accuracy and Precision of Continuous Glucose Monitoring in Hospitalized Patients Undergoing Radiology Procedures

摘要

The use of continuous glucose monitoring (CGM) has increased steadily over the past decade. 1 As these devices become more pervasive in the outpatient setting, there is increasing interest in using CGM for inpatient management of diabetes. This raises concerns regarding safety in the set- ting of radiology imaging. Current industry guidelines recom- mend removal of devices when undergoing certain radiology procedures due to potential interference with CGM system functioning. 2 Expert opinion has suggested placing a lead apron over the device prior to x-ray, CT scan, or catheteriza- tion procedures. 3,4 However, there is no published data on the impact of radiation and contrast exposure on CGM precision and accuracy to support these recommendations.
