The most commonly employed T2 mapping techniques are 2D and make use of ECG-triggering. This may be a limitation in patients with variable heart rate and complex three-dimensional conditions. To address these limitations, we here propose an isotropic free-running 3D T2 mapping technique that avoids ECG triggering by using Pilot Tone navigation. In three healthy volunteers, our technique produced accurate isotropic T2 maps when compared to 2D T2 prepared bSSFP (T2=41.1±4.8ms vs. 44.9±3.3ms, respectively, p=0.1), and cardiac motion was successfully resolved.
