Abstract:
A method of magnetic resonance imaging a flowing liquid flowing through a column of space having a long axis, comprising the steps of:obtaining imaging readings from reading points throughout said column by utilizing a frequency encoding gradient to define the position of a reading point in the direction of the long axis of said column; anddefining the position of a reading point in a plane normal to the long axis of the column using phase encoding gradients and echo-planar blips;wherein eco-planar blips with odd echoes and even echoes are used to acquire readings in two distinct regions of k-space while the velocity phase sensitivity of said frequency encoding gradient is adjusted to ensure phase continuity between said regions of k-space; andobtaining readings in each plane normal to the long axis of the column from a matrix of reading points using a plurality of phase encoding steps and a plurality of echo interleaves.
