Local and global SNR of in vivo MR images are often measured to evaluate the image quality. Due to the density variation of in vivo images, the motion during the acquisition and other aspects, the SNR measurement of the in vivo image, especially at high field MRI, is much more complicated. The purpose of this work is to evaluate and compare SNR calculation methods to provide the reference or guidance for in vivo image SNR measurements.
