The invention provides a brain longitudinal relaxation value measuring method and an apparatus. The method comprises the following steps of applying an IR radio frequency pulse to a preset numbers of layers to enable a magnetized vector in the preset numbers of layers to turn over in 180-degree, and collecting a T1 image for a magnetized vector restoring curve in the preset numbers of layers via a staggered collection mode. The layer is an image layer formed via brain magnetic resonance scan; and parallel imaging and part Fourier transform accelerating technologies are employed during the T1 image collection by the staggered collection mode. T1 image collection time can be greatly shortened by the use of the above method and apparatus.
