MRI Positive Contrast Method SPIO Tumor detection
In this study, the new Positive Contrast (PC) method was proposed to emphasize the tumors in MRI images. If the object includes magnetic particles such as S PIO(Super Paramagnetic Iron Oxide), the dark image is obtained because of the MRI's distorted magnetic field by the magnetic particles. This effect appears as the shift of peak position in K-space calculated from the Fourier transform of the sub-area of the MRI images. The tumor-emphasized MRI images were obta ined by selecting only the sub-areas that ...
