Differentiation of tumor-infiltrated edema and pure vasogenic edema in patients with brain tumors by using a fractional order calculus model

A fractional order calculus model (FROC) holds promise in differentiating tumor-infiltrated edema from pure vasogenic edema of brain tumors. This study used a q-space Cartesian grid sampling scheme, diffusion spectrum imaging, in patients with high-grade gliomas, meningiomas and brain metastases to generate FROC-based parameters, including D, β and μ. The μ showed the best individual parameter performance in differentiating tumor-infiltrated edema from pure vasogenic edema.
