Effects of blood glucose level on 18F-FDG uptake for PET/CT in normal organs: A systematic review.
<h4>Purpose</h4>To perform a systematic review of the effect of blood glucose levels on 2-Deoxy-2-[18F]fluoro-D-glucose (18F-FDG) uptake in normal organs.<h4>Methods</h4>We searched the MEDLINE, EMBASE and Cochrane databases through 22 April 2017 to identify all relevant stud...

| description | <h4>Purpose</h4>To perform a systematic review of the effect of blood glucose levels on 2-Deoxy-2-[18F]fluoro-D-glucose (18F-FDG) uptake in normal organs.<h4>Methods</h4>We searched the MEDLINE, EMBASE and Cochrane databases through 22 April 2017 to identify all relevant studies using the keywords "PET/CT" (positron emission tomography/computed tomography), "standardized uptake value" (SUV), "glycemia," and "normal." Analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. Maximum and mean SUVs and glycemia were the main parameters analyzed. To objectively measure the magnitude of the association between glycemia and 18F-FDG uptake in different organs, we calculated the effect size (ES) and the coefficient of determination (R2) whenever possible.<h4>Results</h4>The literature search yielded 225 results, and 14 articles met the inclusion criteria; studies included a total of 2714 (range, 51-557) participants. The brain SUV was related significantly and inversely to glycemia (ES = 1.26; R2 0.16-0.58). Although the liver and mediastinal blood pool were significantly affected by glycemia, the magnitudes of these associations were small (ES = 0.24-0.59, R2 = 0.01-0.08) and negligible (R2 = 0.02), respectively. Lung, bone marrow, tumor, spleen, fat, bowel, and stomach 18F-FDG uptakes were not influenced by glycemia. Individual factors other than glycemia can also affect 18F-FDG uptake in different organs, and body mass index appears to be the most important of these factors.<h4>Conclusion</h4>The impact of glycemia on SUVs in most organs is either negligible or too small to be clinically significant. The brain SUV was the only value largely affected by glycemia. |
