Table 2 The myocardium and blood T1 of healthy volunteers (N = 12) at 3 T measured by the proposed sequence and 2D SASHA

From: Three-dimensional free breathing whole heart cardiovascular magnetic resonance T1 mapping at 3 T

  2D SASHA Proposed
2-Param fit 3-Param fit  
LV T1 (ms) (μ ± σ) 1476 ± 53
LV CV (%) 6.1 ± 1.4
Septal T1 (ms) (μ ± σ) 1490 ± 65 1575 ± 59 1512 ± 60
Septal CV (%) 3.9 ± 1.2 5.5 ± 0.9 2.1 ± 0.5
Blood T1 (ms) (μ ± σ) 2281 ± 232 2213 ± 281 2113 ± 142
  1. A mean and CV of T1 was calculated for each subject, then the μ, σ, CV and CV’s standard deviation as shown in the table was calculated by across all subjects
  2. LV left ventricle, μ mean, σ standard deviation, (−) not applicable, CV coefficient of variation
