Patent ID: 8565854

Claim:
A method for magnetic resonance imaging or nuclear magnetic resonance (NMR) spectroscopy comprising: emitting a radio frequency pulse sequence from a radio frequency pulse unit towards an object being subjected to a magnetic field, wherein said object comprises a molecule having an atom with a nuclear spin differing from 0; emitting a gradient pulse sequence from a gradient pulse unit towards said object; detecting in a detector unit, and acquiring a magnetic resonance signal from said object corresponding to said emitted radio frequency pulse sequence, wherein said gradient pulse sequence comprises a first diffusion weighting gradient block with an amplitude G 1 , a mixing block with duration t mix and a second diffusion weighting gradient block with an amplitude G 2 , wherein all of G 1 , t mix and G 2 are either varied, fixed or in on or off mode, wherein the on or off mode has a variable taking one of two values where a first value is zero and a second value is finite, and at least one of G 1 or G 2 is fixed or in on or off mode; and wherein an integral of a gradient over time equals zero within each of the first diffusion weighting gradient block and the second diffusion weighting gradient block.
