Figure 1From: Correcting T2* effects in the myocardial perfusion arterial input function avoids overestimation of myocardial blood flowA stress FLASH perfusion study. The AIF time intensity curves are shown in (a) for the first and second echo. The curve after T2* correction is also plotted, highlighting the underestimation of AIF if T2* effects are not corrected. The pixel-wise MBF maps are shown in (b-d) for T2) corrected AIF and (e-g) for the uncorrected AIF curve. The underestimated AIF Gd concentration leads to overestimated MBFs. For the three ROIs, the MBF values (ml/min/g) with and without T2* correction are 2.22 ± 0.49, 2.01 ± 0.56, 2.03 ± 5.6, 2.34 ± 0.66.Back to article page
