Table 2. T1 and T2 values measured in vivo using IR-bSSFP for three ROIs: LV wall, IVS and LV lateral. Mean and stdev are given across ROIs (rows 6 and 7) and across subjects (column 7). Time delay since intravenous contrast injection (Δt) is provided in second last row and cardiac output in last row.
