WebJan 19, 2024 · T1 weighted image (also referred to as T1WI or the “spin-lattice” relaxation time) is one of the basic pulse sequences in MRI and demonstrates differences in the T1 relaxation times of tissues. A T1WI relies upon the longitudinal relaxation of a tissue’s net magnetization vector (NMV). What is bright T1? WebOct 4, 2024 · Anatomical structures and specific areas are visible as interactive labeled images. Cross sectional anatomy: MRI of the brain An MRI was performed on a healthy subject, with several acquisitions with different weightings: spin-echo T1, T2 and FLAIR, T2 gradient-echo, diffusion, and T1 after gadolinium injection.
