  1. Main static magnetic field
  2. Radiofrequency field
  3. Imaging Gradient fields

• What is SAR?
  1. Definition
  2. FDA limits
  3. Manufacturer operating modes

• Keeping SAR in check
  1. Patient types more prone to SAR
  2. Positioning musts
  3. Sequence balancing

• Parameter interactions
  1. Managing TR using concatenations / acquisitions / packages
  2. Parallel imaging : BOGO sale
     1. Vendor options : parallel imaging
     2. Clinical applications parallel imaging
  3. Flip angle modulation techniques
     1. Do's and don'ts

• MRI conditional implants : clinical application
  1. Example #1 : Medtronic pacemaker
  2. Example # 2: Coronary Stent
  3. Example # 3: Spinal cord stimulator
  4. Example # 4 : Programmable CSF shunt
