1. Describe the fundamental principles of MRI technology, including the identification of MRI machine components, their roles in the imaging process, and the advantages and disadvantages of MRI compared to other diagnostic imaging techniques.

2. Explain the role of atomic structure and magnetic properties in MRI imaging, focusing on the significance of hydrogen nuclei, the properties of MR-active nuclei, and the principles of spin, precession, and Larmor frequency.

3. Analyze the interaction of electromagnetic waves and magnetic fields in MRI, including the principles of the electromagnetic spectrum, the use of resonance and RF excitation pulses, and safety considerations related to electromagnetic wave exposure.

4. Understand the generation and characteristics of MR signals, including the concepts of net magnetization vector (NMV), precession, relaxation processes (T1 and T2), and the application of Faraday’s and Lenz’s laws to understand signal induction and free induction decay (FID).

5. Understand spatial encoding techniques in MRI, encompassing slice-selection, frequency encoding, phase encoding, and the roles of gradient coils in determining spatial resolution and image quality.

6. Evaluate the factors influencing MRI contrast and image optimization, focusing on the differences between T2 and T2* decay, the effects of magnetic field inhomogeneities, and the impact of tissue properties and field strength on relaxation times and signal intensity.
