The effects of reducing the pulse repetition time from 2500 ms to 1000 ms when using spin‐density‐projection‐assisted R2‐magnetic resonance imaging for the purpose of measuring liver iron concentration were evaluated. Repeated liver R2 measurements were made using both protocols on 60 subjects with...
