Assessment of Brain Perfusion with MR Imaging

摘要: A technique for assessing brain perfusion with magnetic resonance (MR) imaging is described. This uses two spin echo sequences that are identical except the second sensitised to blood flow by use of a pair unipolar gradients on either side 180 degree pulse. Differences in phase between displayed sensitivity rates +/- 0.5, 1, and 2 mm/s per full scale (+/- pi radians) deflection. The was validated measurement at these water phantom. Ten patients cerebrovascular disease, multiple sclerosis, cerebral tumor, periventricular leukomalacia, meningitis were studied. grey white matter normally seen adults. Infants differences central peripheral regions brain. Abnormalities all clinical cases. will require further validation but it appears provide totally noninvasive method perfusion.
