Thirteen participants were selected for this study, which lasted 3 to 4 years, depending on the participant. They are all non-smokers and young adults. Ten were included for the entire study, as they received 26 MRI exams but no radiation exposure. Subject number 8 (reported in bold characters) was exposed to repetitive computed tomography exams and was excluded from the global analysis. The two volunteers (number 12 and number 13; in italics) have not yet finished the study and were considered only for the analysis of the effects following the first MRI session.
