CHAPTER 2: MAGNETIC RESONANCE IMAGING

1. Advanced MRI Techniques: 1.Magnetic Resonance Angiography (MRA) 2. Time-of-Flight (TOF) 3.Phase Contrast Method (PC) 4.Diffusion-Weighted Imaging 5.Spectroscopy 6.Functional MRI (fMRI)

2. Clinical Application of MRI: 1.Brain 2.Liver & Reticuloendothelial System 3.Cardiac 4.Musculoskeletal 5.Abdominal/Pelvic

3. SAFETY PRECAUTIONS: • Leave any metal object outside of the building. • Check with MRI Operator if access is needed in the room with the magnet. Do not go into the Magnet Room alone • Check with the manager if the room needs to be entered at night or off duty times. • Respect the potential for injury.
