Increasing chromosomal instability due to terminal deletions during the first 20 MRI sessions. Between 846 and 3,357 metaphases were observed for each time point and participant after telomere/centromere staining. Various cytogenetic parameters were scored: dicentric chromosomes and rings (a); total type E acentrics (excess acentric fragments) (b), total chromosomal breaks (c), damaged cells (d), 2-T acentric fragments resulting from two chromosomal breaks and fusion (e), 1-T acentric fragments equivalent to a terminal deletion (f), and 0-T acentric fragments resulting from two chromosomal breaks in the same chromosomal arm (g). h Table presenting the stratified statistical analysis (correlation coefficients and p values). Ac, Acentric fragment; Dic, Dicentric chromosomes; MRI, Magnetic resonance imaging; T, Telomere
