#1)The recieve bandwidth affects:
a)Chemical shift artifact
b)SNR
c)Slice Thickness Resolution
d)a & b
A)The answer is d).
Chemical shift increases as bandwidth decreases and SNR increases. Chemical shift is more prevelent in high field systems.
#2)When imaging the hip avascular necrosis can be visualized by exploiting the chemical shift artifact using:
a)Out of phase imaging
d)In phase imaging
e) a & b
A) The answer is e).
Most people are familiar with out of phase imaging, especially when imaging adrenal glands, but the Dixon technique may not be as well know. click on the link to learn more about it.
