Magnetic resonance imaging apparatus, image generating method and computer-readable non-volatile storage medium storing medical image processing program

An image generating method comprising:

• in a first transition period in which a first Magnetization Transfer (MT) pulse sequence is applied repeatedly until magnetization is transited to a first steady state, repeating application of the first MT pulse sequence and acquisition of a first Magnetic Resonance (MR) signal corresponding to a first frequency region that is a part of a k-space;
• in the first steady state, repeating application of the first MT pulse sequence and acquisition of a second MR signal corresponding to a second frequency region of the k-space, frequency of the second frequency region being lower than a frequency of the first frequency region;
• in a second transition period in which a second MT pulse sequence, which is different from the first MT pulse sequence, is applied repeatedly until the magnetization is transited to a second steady state, repeating application of the second MT pulse and acquisition of a third MR signal corresponding to a third frequency region that is another part of the k-space different from the first frequency region, a frequency of the third frequency region being higher than the frequency of the second frequency region;
• and
• generating one MR image based on the first MR signal, the second MR signal, and the third MR signal.

A non-transitory computer-readable medium storing a medical image processing program that causes a computer to perform:

• in a first transition period in which a first Magnetization Transfer (MT) pulse sequence is applied repeatedly until magnetization is transited to a first steady state, repeating application of the first MT pulse sequence and acquisition of a first Magnetic Resonance (MR) signal corresponding to a first frequency region that is a part of a k-space;
• in the first steady state, repeating application of the first MT pulse sequence and acquisition of a second MR signal corresponding to a second frequency region of the k-space, a frequency of the second frequency region being lower than a frequency of the first frequency region;
• in a second transition period in which a second MT pulse sequence, which is different from the first MT pulse sequence, is applied repeatedly until the magnetization is transited to a second steady state, repeating application of the second MT pulse sequence and acquisition of a third MR signal corresponding to a third frequency region that is another part of the k-space different from the first frequency region, a frequency of the third frequency region being higher than the frequency of the second frequency region;
• and
• generating one MR image based on the first MR signal, the second MR signal, and the third MR signal.
