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.
