A functional image creating method and a functional image creating apparatus, each enabling rendering of an activated region, are provided. A phase difference image PDr(x) is created using a complex image &#x3c3;r(x) created from an MR signal in an inactive state and a complex image &#x3c3;'r(x) obtained by filtering the complex image &#x3c3;r(x). A phase difference image PDa(x) is created using a complex image &#x3c3;a(x) created from an MR signal in an active state and a complex image &#x3c3;&#x2032;a(x) obtained by filtering the complex image &#x3c3;a(x). Function signal images diff() and diff() are created using the phase difference images PDr(x) and PDa(x), respectively. A magnitude image Mr(x), a magnitude image Ma(x), a standard image, or a morphological image I(x) is masked with the function signal image diff() or diff(), thereby a function image I&#x2032;(x) with an activated region rendered is created.
