Method for acquiring magnetic resonance images using T2 * mapping based on the echo planar method

摘要

The present invention uses an EPI image that obtains multiple MRI images at different echo times within a rise time (TR) after application of an excitation RF pulse, for up to 256 MRI images that obtain different echo times. Flip curve fitting. The T2 * value is then fitted based on a sufficient amount of TE images, so it is far more than provided by an underestimated or overestimated fitting with existing methods based only on 12 images. Accurate T2 * values can be provided, and data can be obtained quickly and accurately without neural stimulation or acoustic noise. Furthermore, the flipped fitting method shows the actual T2 * value more appropriately and accurately.
