Effect of MRI on Blood Glucose Level of Patients

Abstract

Background & Objective: There are reports of the effect of magnetic fields on blood glucose level. But no final agreement has yet been reached on whether to reject or accept these reports. The objective of this study is to evaluate the effect of MRI with magnetic strength of 0.35 Tesla on blood glucose level in patients.

Materials & Methods: This is an analytical study performed at Gonabad MRI Center; 100 patients referred to MRI center were selected by convenient sampling method. Blood glucose was determined before and after entering the imaging room by a glucometer. Data analysis was performed using SPSS software version 14.5 using Wilcoxon test (P-value<0.05).

Results: The results showed that the mean blood glucose level of patients referred to the MRI center was 112.15 ± 20.39 before MRI and 104.03 ± 15.97 mg/dl after MRI (p<0.001), which showed a significant decrease in blood glucose level.

Conclusion: The findings show that MRI with a magnetic field strength of 0.35 Tesla can lower blood glucose level. Therefore, it is recommended to measure this level in people who should not have hypoglycemia before MRI.
