1. MR image quality is mainly determined by three main factors: signal to noise ratio (SNR), resolution and scan speed. 2. Most MR image quality problems mainly affect one of these three categories, and recognition of the main problem area is the first step in image optimization. 3. Diagnostic quality images may be obtained if compromises to the other two areas may be tolerated. 4. Scanning at 3T allows significant gains in SNR, which then may be reinvested to improve resolution and scan speed.

1. Determinants of MR image quality and examples      a. Signal to noise ratio (SNR)      b. Resolution      c. Scan speed 2. How to recognize the main culprit that is causing poor image quality. 3. Determining where compromises can be made and making appropriate changes. 4. Reinvesting signal gains from 3T imaging to improve resolution and scan speed.
