Patent ID: 7787930

Claim:
A magnetic resonance imaging method, comprising: with a radio-frequency (RF) coil, applying a magnetic field so as to rotate at least a portion of a longitudinal magnetization of a specimen into a transverse plane throughout a specimen volume to establish a transverse magnetization; allowing the transverse magnetization to evolve for a time period of about T E /4; selecting a first adiabatic radio-frequency (RF) pulse having an amplitude modulation and a frequency modulation; applying an RF magnetic field based on the first adiabatic RF pulse so as to substantially invert a component of the transverse magnetization; allowing the inverted transverse magnetization to evolve for a time period of about T E /2; selecting a second adiabatic radio-frequency (RF) pulse having an amplitude modulation and a frequency modulation; applying an RF magnetic field based on the second adiabatic RF pulse so as to substantially invert a component of the transverse magnetization; allowing the inverted transverse magnetization to evolve for a time period of about T E /4; rotating at least a portion of the transverse magnetization so as to produce a stored T 2 -weighted longitudinal magnetization; and obtaining a specimen image associated with the specimen volume based on the stored T 2 -weighted longitudinal magnetization.
