tisu 4d4D bioprinting offers ample opportunities for the production of complex dynamical constructs with hh resolution, otherwise inaccessible through other biofabrication methodsTissue 4D is a software tool for analyzing dynamic-contrast enhanced (DCE) and perfusion-wehted MRI datasets. It can help in the detection of tumor tissues in organs such as the liver by visualizing regions of strong wash-in and wash-out
