➡️ LESSON DESCRIPTION:
This lesson covers conventional spin-echo pulse sequences in MRI, detailing how they utilize 90-degree and 180-degree radiofrequency pulses to produce high-quality images by refocusing dephased spins. It explores the technique's benefits, such as improved image clarity and versatility, and addresses its drawbacks, including longer scan times and sensitivity to motion. Objectives: 1. Define conventional spin-echo 2. Explain the mechanism of conventional spin-echo 3. Discuss the advantages and disadvantages of conventional spin-echo 4. Identify the suggested parameter selections for single echoes
