Abstract:
1. A magnetic resonance imaging (MRI) method of obtaining MRI images of a patient and storing the images in physical storage media comprising: obtaining a first single shot arterial spin labeled (ASL) three-dimensional (3D) echo train comprising: obtaining a second single shot ASL 3D echo train in essentially the same manner as the first echo train but with a shifted timing so that intrinsic T2 signal amplitude differences are opposite to those of the first echo train and the first k-space, and using the second echo train to fill in a second k-space such that for lines in matching positions in k-space high amplitude signals for the first k-space are low amplitude signals for the second k-space and vice versa; averaging complex data of matching k-space encoding of the first and second k-spaces to create a resulting averaged k-space; using the averaged k-space to generate one or more MRI images; and storing the MRI images in physical storage media.
