Medicinal composition

A magnetic resonance imaging method compring:

• a step of setting an RF receiving coil, which comprises at least three RF receiving coils disposed in each of at least two orthogonal directions and have predetermined sensitivity distributions in the respective directions, to a patient;
• a step of setting any one direction of the two directions as a phase encoding direction as well as measuring the magnetic resonance signals generated from the patient by executing a pulse sequence while thinning phase encoding steps;
• obtaining an MR image without the aliasing of the image by executing an arithmetic operation based on the magnetic resonance signals measured by at least the three RF receiving coils disposed in the set phase encoding direction and based on the sensitivity distributions of the respective RF receiving coils in the phase encoding direction thereof;
• and
• a step of displaying the thus obtained MR image.

A magnetic resonance imaging apparatus comprising:

• magnetic field generation means for applying gradient magnetic fields and high frequency magnetic fields to a patient placed in static magnetic fields in a predetermined pulse sequence while thinning phase encoding steps, a receiving coil group comprising a plurality of RF receiving coils for receiving the nuclear magnetic resonance signals generated from the patient, and image reconstruction means for reconstructing an image by processing the nuclear magnetic resonance signals, wherein
• the receiving coil group comprises at least one main RF receiving coil having a high sensitivity region in a diagnosing portion of the patient and at least two sets of auxiliary RF receiving coil groups each set including at least two auxiliary RF receiving coils disposed in confrontation with each other across the diagnosing portion in each of at least two orthogonal directions, and the high sensitivity region of the respective auxiliary RF receiving coils is formed narrower than that of the main RF receiving coil;
• and
