Are the recorded data of flash glucose monitoring systems influenced by radiological examinations?

The FreeStyle Libre Pro ® flash glucose monitoring system is easy to use in diabetes care. However, the influence of radiological examination on recorded data has not been reported. The sensor should be removed prior to examinations involving strong magnetic or electromagnetic radiation. In the present study, it was assumed that radiological examination was performed without removing the FreeStyle Libre Pro ® sensor in certain unanticipated situations. We researched the integrity of data recorded by the FreeStyle Libre Pro ® system following exposure to chest X-rays, computed tomography (CT), radiotherapy (RT), and magnetic resonance imaging (MRI). Fifty sensors were exposed to chest X-ray, CT, RT, and MRI (1.5-T and 3.0-T), and the recorded data were compared with those obtained before the tests. Ten sensors were included in each group. There were no unread data or errors when the sensors were read. No change was observed before and after the examination for all tests.
