T1

In magnetic resonance, the time for 63% of longitudinal relaxation to occur; the value is a function of magnetic field strength and the chemical environment of the hydrogen nucleus; for protons in fat and in water, in a 1.5T magnet, about 250 milliseconds and 3000 milliseconds, respectively. A T1-weighted image will have a bright fat signal.
