➡️ LESSON DESCRIPTION:
This lesson provides an overview of relaxation processes in MRI imaging, focusing on the role of spin-lattice (T1 recovery) and spin-spin (T2 decay) relaxation in affecting image contrast. It explains how different tissues' inherent T1 and T2 properties influence their appearance on MRI images, enhancing diagnostic accuracy through the manipulation of MRI parameters. Objectives: 1. Define relaxation as it applies to MR imaging, including the types of relaxation that occur: spine-lattice and spin-spin 2. Elaborate on T1 relaxation and explain how and why it varies with different tissues 3. Elaborate on T2 decay and explain how and why it varies with different tissues 4. Understand how utilizing higher field strength systems impacts the relaxation times of tissues.
