T2 weighted image
Dr Jeremy Jones et al.
T2 weighted image (also referred to as T2WI) is one of the basic pulse sequences in MRI and demonstrates the differences in the T2 relaxation time of tissues.
The T2WI relies upon the transverse relaxation of the net magnetisation vector (NMV). T2 weighting tend to have long TE and TR times.
Paramagnetic contrast agents, e.g. gadolinium-containing compounds, do not have nearly as significant effect as they do in T1WI.
Summary
- TR: long
- TE: long
- fat: intermediate-bright
- fluid: bright
