Deep vascular congestion in dural venous thrombosis on computed tomography.

abstract：:Due to the low prevalence of hemangiopericytomas (HPCs), data on the biophysiological characteristics of this tumor are rare. Positron emission tomography (PET) demonstrated a sixfold increased uptake of [11C]methionine and hyperperfusion in the HPC, whereas glucose utilization was decreased in this area. This low glu...
