Sensitivity of MRI

This lecture covers the fundamentals of Magnetic Resonance Imaging (MRI), focusing on the sensitivity of MRI and how it can be increased by adjusting the magnetic field strength. The instructor explains the essentials of MRI, including nuclear equilibrium magnetization and the relationship between spins and magnetic fields. Different magnetic field strengths are discussed in the context of MRI applications, such as imaging the brain, abdomen, spine, and breast. The lecture also touches on the maximum possible MR signal and the factors influencing it, providing insights into optimizing MRI sensitivity.
