The Echo Train Length is one of the parameters that determines the tissue weighting of the resulting image. Shorter Echo Trains produce [1] weighted images, and longer Echo Trains produce [2] weighed images. 

In reference to a Gradient Echo sequence…. There is no 180o RF pulse, instead the re-phasing is done by a ____________ 

Select the pulse sequences that we have studied in class….

Dual Contrast Spin Echo… Also called a Variable Echo Multi Planar (VEMP) is a sequence that allows two different tissue weightings, [1] and [2], in the same sequence.  

Regarding the filling of K-Space…. The steeper the phase slope, the smaller the signal amplitude. The shallower the phase slope the greater the signal amplitude. Is this True or False? [1] The lower amplitude signals are centered in K-Space with the higher amplitude signals extending outward to the edges. Is this True or False? [2]

In plants, the swelling of cells placed in a hypotonic solution results in ______.

Which of the following is a characteristic of the cell membrane?

Following from the previous question… The prosecutor for the case is not satisfied with the results of the DNA comparison and has asked the lab to redo the analysis to increase the certainty of a match between the crime scene and suspect DNA. What would be the best approach for the lab in meeting this request?
