1. Differentiate between intrinsic and extrinsic contrast parameters and describe how they influence tissue visualization in MRI images, including T1, T2, and proton density (PD) contrasts.

2. Define repetition time (TR) and echo time (TE), and explain how these parameters influence signal intensity and contrast in T1, T2, and PD-weighted imaging.

3. Identify and sequence the events in an MRI pulse sequence, explaining the timing and function of RF pulses and gradient applications in creating spatially localized and diagnostically valuable images.

4. Explain specialized MRI techniques such as Diffusion Weighted Imaging (DWI), Susceptibility Weighted Imaging (SWI), Functional MRI (fMRI), and Magnetization Transfer Contrast (MTC), and identify their clinical applications.

Compare and contrast the signal amplitudes of different tissues across T1, T2, and PD-weighted images,

6. Explain the influence of relaxation times, proton density, and tissue composition on signal intensity and contrast.

7. Articulate adjustment of MRI parameters such as TE, TR, and flip angles to achieve specific contrast weighting to enhance diagnostic clarity.
