PROBLEM TO BE SOLVED: To provide a method for collecting the spatially encoded spin resonance data of an inspected zone including an atomic spin having a spin-lattice relaxation time, a spin-spin relaxation time and an effective spin-spin relaxation time. SOLUTION: At least three consecutive high-frequency pulses having a flip angle unequal to 180 degrees and the integer times thereof are applied, and a time intervalτbetween the first and the second high-frequency pulses of the consecutive high-frequency pulses is selected at a value larger than T2eff , but smaller than 5T2eff . A time interval (T-τ) between the second and the third high-frequency pulses is selected at a value larger than T2eff but smaller than 5T1 . In addition, one of gradient magnetic fields is applied to an examination zone during a period between the first and second high frequency pulses, or at least during one period of the consecutive high-frequency pulses, thereby detecting at least one induced echo.
