Robust reconstruction of cardiac T1 maps using RNNs

Autor: Martini, Nicola, Vatti, Alessio, Ripoli, Andrea, Salaris, Sara, Santini, Gianmarco, Santarelli, Maria Filomena, Chiappino, Dante, Della Latta, Daniele

Cardiac magnetic resonance parametric T1 maps are typically reconstructed using non-linear fitting. However this method has limitations due to the high computational cost and robustness. In this study, a recurrent neural network (RNN) is proposed for

Automatic Characterization of Myocardial Perfusion in Contrast Enhanced MRI

Autor: Landini Luigi, Positano Vincenzo, Santarelli Maria Filomena

Publikováno v: EURASIP Journal on Advances in Signal Processing, Vol 2003, Iss 5, p 760802 (2003)

The use of contrast medium in cardiac MRI allows joining the high-resolution anatomical information provided by standard magnetic resonance with functional information obtained by means of the perfusion of contrast agent in myocardial tissues. The cu

Probabilistic Graphical Modeling approach to dynamic PET direct parametric map estimation and image reconstruction

Autor: Scipioni, Michele, Pedemonte, Stefano, Santarelli, Maria Filomena, Landini, Luigi

In the context of dynamic emission tomography, the conventional processing pipeline consists of independent image reconstruction of single time frames, followed by the application of a suitable kinetic model to time activity curves (TACs) at the voxe
