Analysis of T1 and T2 Relaxation Times from Bloch Equation for the Estimation of Age of Human Organs

Abstract

As one of the preferred diagnostic imaging tools, Magnetic Resonance Imaging (MRI) has become a diagnostic modality which has made an in- road into age estimation. However, many works in this area were carried out using observed statistical data to classify and analyze findings. In this research work, a time-independent non-homogenous linear differential equation from the Bloch Nuclear Magnetic Resonance (NMR) equations is evolved. The equation is solved under the influence of radio frequency magnetic field [rfB_(1 ) (x,t)≠0] and in the absence of radio frequency magnetic field [rfB_(1 ) (x,t)=0] T₁and T2 relaxation times were varied with a view to analyze the signals as it relates to the age of any human organ.
