With more than 30 million scans per year in European countries, Magnetic Resonance Imaging (MRI) is one of the most important tomographic tools adopted in clinical practice. Nevertheless, standard MRI results mostly have a qualitative nature (i.e. they display a contrast between different tissues, which must be interpreted by visual inspection and requires the presence of healthy reference tissues) that limits their objectivity and comparability. The project will evaluate the suitability of two complementary MR-based emerging techniques, Electrical Properties Tomography (EPT) and Magnetic Resonance Fingerprinting (MRF), to bring a “quantitative revolution” in MRI results, so that each image pixel is associated with the measurement (including uncertainty) of one or more tissue parameters. This will be done through a complete metrological characterisation of the EPT and MRF performances, to provide the clinical community with a quantification of their reliability as diagnostic tools.
