In perfusion weighted imaging, what happens to the signal intensity as the bolus of
contrast media passes?

It gets darker on T2* images
The MRI system's host computer is responsible for:

communicating the sequence parameters to the rest of the system
components.
, A janitor feels a force on a metal bucket when he is 8ft from isocenter. The force is
atleast ____ times stronger if he moves in to 2ft from isocenter.

When RF energy is repeatedly transmitted into the same tissue of the body, one
would expect what to occur over time, regarding the amplitude of the net
magnetization of protons contained within the disturbed tissues?
Give this one a try later!
the net magnetization would decrease in amplitude
Nursing mothers should suspend breast feeding for how many hours after contrast
injection?
