Aims and objectives
In recent years,
technological developments of MRI scanners have allowed the mapping sequences to become clinically feasible: these sequences generate parametric maps able to display tissue magnetic properties [1,
Qualitative and quantitative information of tissues  should be obtained through the appropriate image acquisition and analysis of the body physical properties,
like spin-lattice relaxation times (T1) and spin-spin relaxation times (T2).
A new approach to the evaluation of standardization will be necessary in order to take in to account the possibility of finding T1 and T2 mapping independence from the MRI scanners used.
Aim of this study was the assessment of the standardization in measuring nuclear relaxation times for 1H nuclei from post-processing of phantom images acquired with different vendor clinical magnetic resonance imaging (MRI) scanners and a NMR spectrometer.
