CT scanning
This type of imaging uses radio frequency waves in a magnetic field interacting with tissues to produce information/signals
a. MRI
b. CT
c. Dx US
d. plain film radiograph
MRI
This type of imaging takes the information/signals/data collected relates to tissues re-emission of radio frequency while in the magnetic field
a. MRI
b. CT
c. Dx US
d. plain film radiograph
MRI
This type of imaging is data collected from a measure of energy emitted from tissue molecules after stimulation by radio waves
a. MRI
b. CT
c. Dx US
d. plain film radiograph
MRI
Energy emitted _ with various tissues which leads to tissue _
differs
differentiatoin
Both relate to realignment of tissue molecules with the magnetic field after radiofrequency wave has been turned off

This imaging measures energy released shortly after RF turned off
a. T1 imaging
b. T2 imaging
c. MRI imaging
d. CT scans
T1 imaging
