초록
Perfusion MRI is useful for pathological changes and provides quantitative informationabout cerebral blood vessels. Perfusion has an exogenous perfusion imaging techniqueusing the first-pass technique, which have an endogenous perfusion imaging technique usingmagnetization transfer, the spin tagging (ST) technique. There are DSC and DCE methods for theuse of exogenous contrast medium, and there are PASL and CASL for the endogenous methodwithout using contrast medium. These two types of techniques require selective screening ofthe patient̓s condition or the information they wish to provide. In general, DSC techniques areapplied to patients with acute cerebral hemolytic disease, and DSE methods are provided forpatients with brain tumors. In addition, CASL is applied to allergy, fertile women, nephropathy,and pediatric patients with ST techniques. Perfusion MRI, unlike SPECT, is useful in an agingsociety with differentiated techniques that do not use radioactive materials and will be applied toquantitatively analyze various diseases in the future.
