A collaboration between researchers of the Yamanashi University (Japan) and the CEA showed that it is possible to characterize liver lesions from their elastic properties estimated virtually from MRI measurements of the molecular diffusion of the water. The MRI is thus an interesting option to succeed the conventional MRI elastography used in these exams, the latter with defects (low resolution images, heavy implementation). This work was published in the journal Radiology on June 12, 2017.
