Method for improving the sensitivity of magnetic resonance imaging (MRI) for magnetic susceptibility effects.

摘要

PRESENTS A METHOD TO IMPROVE THE SENSITIVITY OF IMAGING BY ECO CALL FOR GRADIENT FOR EFFECTS T2 * IN IMAGING USING MAGNETIC RESONANCE DYNAMICS comprising the steps of delaying ECHOES CALLED gradient so that the ECOS CALLED BY gradient EXPOSED TO THE EFFECTS OF MAGNETIC SUSCEPTIBILITY FOR AN EXTENDED PERIOD OF TIME. ECHOES are delayed beyond a RF pulse SUBSEQUENT by applying a gradient FURTHER THAT Offsets ANY ECO CALL FOR GRADIENT Spins BE EXCITED AT THE TIME PERIOD OF REPLAY OF RADIO WAVES IN WHICH PRODUCED SUCH ECOS.
