TITLE Gradient Echo Imaging SPEAKER NAME Daniel

INTRODUCTION Gradient echo (GRE) imaging has a wide range of clinically useful applications. In particular, GRE imaging is frequently used in the clinic for anatomical/structural imaging and imaging dynamics for diseases that span all organ systems and numerous pathologies. In general, an advantage of GRE imaging is the fact that it is regarded as “fast” owing to the generally short repetition times (TRs). As a consequence, GRE imaging is especially useful for: proton density-weighted, T1-weighted and T2*-weighted imaging; capturing physiologic motion; perfusion imaging; angiography; real time imaging; and for true 3D imaging. A notable disadvantage is the fact that GRE imaging can’t generally achieve T2-weighted image contrast. This talk will also provide context by succinctly comparing and contrasting spin echo and GRE imaging.
