CORRELATING MR RELAXATION MEASUREMENTS WITH CORRESPONDING PROTEOMIC INFORMATION PROVIDED BY MALDI IMS
The premise of this work is to understand the contrast variations seen in MRI in light of the proteomic composition of tissue. Magnetic resonance imaging (MRI) is now widely used as a primary medical imaging method to visualize the internal structure and function of different tissues in human body....
