Impact of in Vivo High-Field-Strength and Ultra-High-Field-Strength MR Imaging on DNA Double-Strand-Break Formation in Human Lymphocytes

Automated gH2AX foci quantification did not show evidence of increased DNA double-strand breaks after unenhanced or contrast-enhanced in vivo MR imaging at any investigated MR condition, including MR systems with different static magnetic field strengths (1 T, 1.5 T, 3 T, 7 T).
