A single-center prospective trial on the effects of standard of care radiation exposure on the Dexcom G6 continuous glucose monitoring (CGM) device.
To determine if standard of care radiation exposure longitudinally effects the accuracy and precision of the G6 transmitter in the post TPIAT in-patient population. Reduce burden for patients to remove and waste a functional and expensive Dexcom G6 CGM for radiologic procedures.

Dexcom G6 Accuracy Post Radiation Exposure by Clark Error Analysis (Zone A and B %)
Blood Glucose levels (mg/dL) obtained by the Dexcom G6 sensor and transmitter compared to blood glucose levels (mg/dL) obtained by a handheld glucometer until the transmitter is changed. The Clarke Error Grid Analysis method was used to compare absolute values. Accuracy reported as percentage of comparators in Zone A and B.
Time frame: 3 months
Post Radiation Dexcom G6 Transmitter Functional Duration by Clark Error Analysis (Zone A and B %)
Transmitter functional duration is determined by time from TPIAT procedure and CGM placement (baseline) to time for Transmitter changed (approximately 3 months), Functionality is determined by analysis of Blood Glucose (mg/dL) in month groupings (0-1month, 1-2months, 2+ months from baseline. Blood Glucose levels (mg/dL) obtained by the Dexcom G6 sensor and transmitter compared to blood glucose levels (mg/dL) obtained by a handheld glucometer until the transmitter is changed. The Clarke Error Grid Analysis method was used to compare absolute values. Accuracy reported as percentage of comparators in Zone A and B.
