Clinical Trial Summary

The main purpose of this study is to evaluate the overall variation in the assessment of fatty acid uptake and blood flow in adipose tissue and skeletal muscle in the fasted and postprandial states by evaluating the repeatability of whole-body three-dimensional kinetic (4D) combined positron emission tomography and magnetic resonance imaging (PET/MRI) readouts in participants with type 2 diabetes mellitus (T2DM), and non-diabetic control participants. Each volunteer participates 4 scanning sessions.


Clinical Trial Description

A total of approximately 13 T2DM and 6 control subjects (a total of 19 subjects) are planned to be enrolled to achieve 11 T2DM and 5 control subjects to complete the study, assuming a 15% drop-out rate. The test-retest repeatability of the ratio of FTHA uptake rates in subcutaneous adipose tissue (SAT) to skeletal muscle is measured using the intra-class correlation coefficient (ICC). Assuming an ICC of 0.85, with a 5% two-sided type I error rate, a sample size of 16 completers will yield approximately 90% power to detect an ICC statistically significantly greater than 0.4 (usually considered as a criterion for moderate agreement). The total radiaooin burden for tshi sitdu yis 27.4 mSv. The study is approved by the local Ethical committtee and Fimea. ;
