摘要
A magnetic resonance imaging system may include a magnet, gradient coils, an RF pulse transmitter, an RF receiver that receives MR signals from tissue that has been exposed to RF pulses, gradient fields, and a magnetic field, and a computer that includes a processor. The computer may have a configuration that: causes the RF pulse transmitter and gradient coils to emit multiple labeling pulses at predetermined labeling times directed to blood in a subject; causes the RF pulse transmitter, gradient coils, and magnet to generate MR signals directed to tissue at one or more spatial locations within the subject that receives the blood; causes the RF receiver to receive MR signals emitted by the tissue at predetermined imaging times; generates an image of the tissue based on the received MR signals; repeats the foregoing four actions one or more times; and generates information indicative of perfusion within the tissue based on the generated images.
