A magnetic resonance imaging diagnostic apparatus for providing susceptibility weighted images of a region of interest of a subject, comprising: a generating unit (6, 7) adapted to generate a slice gradient magnetic field, a phase-encode gradient magnetic field and a read-out gradient magnetic field that extend in a slice axis, a phase-encode axis, and a read-out axis, respectively; and a creating unit adapted to create an image of the region of interest from a magnetic resonance signal generated in the region of interest by virtue of nuclear magnetic resonance; characterized by further comprising: a control unit (10, 16) adapted to perform an nth-order gradient moment nulling with n being 2 or a greater integer with respect to at least one gradient axis selected from the slice axis, the phase-encode axis, and the read-out axis, the control unit being further adapted to control the generating unit (6, 7) to perform an asymmetric spin-echo pulse sequence in which an echo time is set long enough to cancel the phase shift at any vein in the region of interest, thereby making phase shifts caused by magnetic susceptibility differences dominant and enhancing the ability of visualizing a vein, wherein the asymmetric spinecho pulse sequence involves the application of an excitation pulse, the application of an inversion pulse, and the sampling of an echo, wherein the time interval (Ta) between the excitation pulse and the inversion pulse and the time interval (Tb) between the inversion pulse and the echo peak deviate from half the echo time, and wherein the control unit (10, 16) is further adapted to set a difference between the time intervals (Ta, Tb) to such a value that magnetic susceptibility differences within the region of interest are reflected in the contrast of an image reconstructed from the sampled eachoes. a generating unit (6, 7) adapted to generate a slice gradient magnetic field, a phase-encode gradient magnetic field and a read-out gradient magnetic field that extend in a slice axis, a phase-encode axis, and a read-out axis, respectively; and a creating unit adapted to create an image of the region of interest from a magnetic resonance signal generated in the region of interest by virtue of nuclear magnetic resonance; characterized by further comprising: a control unit (10, 16) adapted to perform an nth-order gradient moment nulling with n being 2 or a greater integer with respect to at least one gradient axis selected from the slice axis, the phase-encode axis, and the read-out axis, the control unit being further adapted to control the generating unit (6, 7) to perform an asymmetric spin-echo pulse sequence in which an echo time is set long enough to cancel the phase shift at any vein in the region of interest, thereby making phase shifts caused by magnetic susceptibility differences dominant and enhancing the ability of visualizing a vein, wherein the asymmetric spinecho pulse sequence involves the application of an excitation pulse, the application of an inversion pulse, and the sampling of an echo, wherein the time interval (Ta) between the excitation pulse and the inversion pulse and the time interval (Tb) between the inversion pulse and the echo peak deviate from half the echo time, and wherein the control unit (10, 16) is further adapted to set a difference between the time intervals (Ta, Tb) to such a value that magnetic susceptibility differences within the region of interest are reflected in the contrast of an image reconstructed from the sampled eachoes. a control unit (10, 16) adapted to perform an nth-order gradient moment nulling with n being 2 or a greater integer with respect to at least one gradient axis selected from the slice axis, the phase-encode axis, and the read-out axis, the control unit being further adapted to control the generating unit (6, 7) to perform an asymmetric spin-echo pulse sequence in which an echo time is set long enough to cancel the phase shift at any vein in the region of interest, thereby making phase shifts caused by magnetic susceptibility differences dominant and enhancing the ability of visualizing a vein, wherein the asymmetric spinecho pulse sequence involves the application of an excitation pulse, the application of an inversion pulse, and the sampling of an echo, wherein the time interval (Ta) between the excitation pulse and the inversion pulse and the time interval (Tb) between the inversion pulse and the echo peak deviate from half the echo time, and wherein the control unit (10, 16) is further adapted to set a difference between the time intervals (Ta, Tb) to such a value that magnetic susceptibility differences within the region of interest are reflected in the contrast of an image reconstructed from the sampled eachoes.
