PROBLEM TO BE SOLVED: To improve resonation by preventing artifacts and promptly thinning an extracted signal which has wide line width which is extracted. SOLUTION: An equipment is provided with a spectrum-measuring means (a) for conducting spectrum measurement without applying magnetic field gradients and measurement applying magnetic field gradients, a signal component extraction means c for extracting one central signal component, by calculating the ultrafine structure constant based on a spectrum without the application of the magnetic field gradients and then calculating the minimum value with a shift of the constant of the ultrafine structure based on a spectrum applied the magnetic field gradient, a narrowing processing means d for converting the central signal component to a spectrum having smaller line width by subjecting to Fourier transformation, frequency filtering, the signal component to inverse Fourier transformation, and an image processing means e for imaging the narrowed spectrum. Then, free radical substance is administered for imaging the distribution of the free radicals in an organism. |
