The invention provides a method for quantitative analysis of nuclear medicine brain imaging. The method comprises retrieving a target image, wherein the target image is a brain image as a nuclear medicine image produced from a radiopharmaceutical, then matching the position of a space axis and the size of a voxel of the target image to a standard template by an affine transformation, wherein the standard template comprises a relative position of striatum. The method further comprises selecting the striatum from the target image according to the relative position of the striatum in the standard template and calculating an average value of the striatum, dividing the striatum from the target image and calculating a background value based on a remainder pixel value of the target image, and a specific uptake ratio is calculated based on the average value of the striatum and the background value. |
