Differentiation of primary central nervous system lymphoma and high-grade glioma with dynamic susceptibility contrast-enhanced perfusion magnetic resonance imaging

Abstract

The difference in DSC perfusion MRI characteristics between PCNSLs and high-grade gliomas is determined by their different vascularities and different patterns of contrast agent leakage. This difference may be helpful in the diagnosis and preoperative differentiation between PCNSLs and high-grade gliomas, which sometimes may have similar conventional MR imaging appearance.
