➡️ LESSON DESCRIPTION:
This lesson offers a comprehensive exploration of the fundamental principles of MRI, emphasizing the role of resonance in generating images. It covers the specifics of RF excitation pulses, their interaction with hydrogen nuclei, and the resultant alterations in magnetization, detailing the critical concepts of tilt, flip angle, and the transition of the net magnetic vector from the longitudinal to the transverse plane. Objectives: 1. Define resonance 2. Define RF excitation pulse 3. Discuss the results of resonance as it relates to classical theory 4. Discuss the results of resonance as it relates to quantum theory 5. Discuss flip angle, longitudinal plane, and transverse plane in terms of the RF energy applied
