T1, or spin-lattice relaxation time, describes the time it takes for the longitudinal magnetization to return to its equilibrium state after being disturbed, not the transverse magnetization. It is related to the interactions between the spins and their surroundings (the lattice), and can vary depending on the molecular environment, making it different for various samples and biological tissues.
