Abstract:
A computer-implemented method of performing magnetic resonance imaging with ultra-short echo time pulse sequences includes defining short T2 threshold limits for enhancement. A multi-echo ultra-short echo time response is acquired and a complex dataset is determined based on the multi-echo ultra-short echo time response. A plurality of phase components is identified from the complex dataset, wherein each phase component is associated with a T2 relaxation time within the short T2 threshold limits. A plurality of frequency components is also identified from the complex dataset, wherein each frequency component is associated with the T2 relaxation time within the short T2 threshold limits. Next, a magnitude dataset is derived from the complex dataset and a fitting algorithm is applied to the magnitude dataset to yield a plurality of magnitude components, wherein each magnitude component is associated with the T2 relaxation time within the short T2 threshold limits. A plurality of phase masks are created based on the plurality of phase components and the plurality of frequency components. These phase masks are applied to the magnitude dataset to obtain a combined dataset. Then, an image based on the combined dataset may be presented on a display.
