How does a long TR combined with a long TE minimize T1 and maximize T2 contrast?

List 3 advantages of EPI.

If a tissue happens to have longitudinal magnetization close to zero at the end of the T1 interval, it will provide little to no signal and make no significant contribution to the magnitude reconstructed IR image. This is considered to be _________ point.

It is generally recommended that contrast enhancement but utilized with STIR imaging.

What specific component is lacking in a gradient echo that would normally correct for inhomogeneities?

Whenever the NMV is kept under 90 degrees, it is said to be partially saturated.

As the magnetic field strength increases the energy between between the two populations of magnetic moments increases so that more energy is required to produce resonance>

What is the relationship gradient slopes and and the difference in precessional frequency between two points on the gradient.

Utilizing extrinsic factors, explain how you obtain T2* weighting in gradient echo imaging. discuss TE, TR and flip angle.

What tissue has the slowest tumbling rate?
