From: Correcting T2* effects in the myocardial perfusion arterial input function avoids overestimation of myocardial blood flow

Figure 1

A 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.
