Answer the following in a well-developed essay. Remember that the story you choose to write about in this essay may not be used for the second essay question.   Fiction, although it is “made up,” is often used as a means of social commentary.  Authors create characters and situations that reflect the world around them, and through creative writing present the reader with thought-provoking tales that challenge them to think more deeply about a given topic.  Of all the stories we’ve read during the course, which would you point to as an example of this type of fiction?  Discuss what the author is commenting on and the effect the story has upon the reader, as well as the way in which the author crafts this effect.

Anne.jpeg What artifact is identified in the image?

What technique generates images with a certain contrast that involves the fast exchange of energy between bound and free nuclei?

The current Dixon-type sequences produce four sets of images, water only, fat only, in-phase, and out-of-phase, due to acquiring echos with different TRs and the same TEs.

Noise is the voltage induced in the receiver coil by the precession of the net magnetic vector (NMV) in the transverse plane.

It is crucial to ensure that coils outside the field of view are turned off to minimize annefact artifacts.

The frequency and phase encoding directions can be swapped to prevent phase mismapping artifacts.

What does a longer Repetition Time (TR) generally yield in MRI?

What kind of artifact is produced by abnormal loading on the coil?

The effectiveness of image contrast in MRI is solely based on patient anatomy.
