Interleaved DCE and DSC-MRI
Original language description
Perfusion MRI is a popular diagnostics method for oncological diseases. There are two methods based on: T1 (DCE) or T2 (DSC) weighted acquisition. Basic DCE methods do not provide all intravascular perfusion parameters, but model mostly the contrast-agent extravasation. On the other hand, classical DSC methods provide only intravascular parameters valid in case of no extravasation. This contribution aims at combination of DSC and DCE-MRI to use their complimentary advantages in a new interleaved DCE-DSC-DCE acquisition and data processing. The use of the advanced aaTH model with Parkers AIF allows estimation of intravascular parameters also by the DCE method. In case of DSC, the effect of the contrast agent extravasation present in tumours is reduced by application of two contrast-agent boluses. Knowing the bolus peak times and doses, the contrast and post-contrast DCE sequences are connected and approximated by the aaTH model. This allows comparison of the intravascular parameters obt
