The holidays are just around the corner, and for many people, that means traveling, and more specifically, traveling through airport security. A recent report in the journal Diabetes Technologies & Therapeutics outlines some information regarding airport full-body scanners that people using insulin pumps or continuous glucose monitors will want to know.

According to the authors, insulin pumps, continuous glucose monitors, continuous gluocose monitor transmitters, and Medtronic’s iPro Recorder are at risk of electromagnetic malfunction if they are brought through imaging devices such as airport body scanners, computer-assisted tomography (CAT) scanners, x-rays, magnetic resonance imaging (MRI), and positron emission tomography (PET) scanners. These devices are not affected by airport metal detectors. (Images of a backscatter machine and a millimeter wave scanner, two types of full-body scanners, can be found here and here, respectively. An image of a traditional airport metal detector can be found here.)

Anyone who has any of these devices should opt out of a full-body scan in favor of screening with a metal detector or a pat-down. The authors recommend that people with diabetes obtain a travel letter from their physician that can be presented to security personnel detailing the specific supplies they must keep with them during their travels. They further suggest that the letter include a statement indicating that the relevant medical device or devices not be exposed to magnetic x-ray equipment, including full-body scanners, but instead should be hand checked.

“Given the increased use of insulin pump therapy, not only in the US, but around the world, with hundreds of thousands of people using this technology, it seems critical that more research is funded to better understand and potentially repair this problem,” notes Irl Hirsch, MD, Senior Editor of Diabetes Technology & Therapeutics and Professor of Medicine at the University of Washington Medical Center-Roosevelt.

  1. Any scanning system - xray style has capability to erase the read only roms storing operating code of the particular microprocessors being used in cgms and pumps.

    Most times this is not big issue but it lurks out there and if enough energy in scans, the roms get erased.

    Most read only roms in use unless a masked memory device use capatitor tecknology that the energy beam of scanners removes the charge on the capacitors - nee - erases them.

    Thus recommendation is to opt out of body scanning and select hand scanning and pat down. Other tip is to pass any equipemt at risk for direct inspection and not put through the xray of baggage scanning.

    Generally more modern chip technology should be more resistant but no guarantee.
