Question

To perform a proper Axial T2 weighted image of the Brain, you would utilize a __________ TR and a _________ TE

Answer 1

For an Axial T2-weighted MRI of the brain, a long TR and a long TE are utilized to provide contrast and detect water retention differences in tissues.

Step-by-step explanation:

To perform a proper Axial T2 weighted image of the Brain, you would utilize a long TR (Repetition Time) and a long TE (Echo Time). T2-weighted MRI uses a longer repetition time (TR) and a longer echo time (TE) to provide good contrast and display differences in the tissues' retention of water. In T2-weighted images, fluids such as cerebrospinal fluid (CSF) appear bright, and this modality is particularly helpful in identifying edema and lesions in the brain.
