Abstract Background In pediatric radiotherapy treatment planning of abdominal tumors, dose constraints to the pancreatic tail/spleen are applied to reduce late toxicity. In this study, an analysis of inter- and intrafraction motion of the pancreatic

Dual-energy CT and CT perfusion for improved CT stroke imaging

Autor: Fasco van Ommen

CT is often used as the modality of choice for the diagnosis of patients with suspicion of stroke. CT imaging allows visualization of occluded blood vessels and identification of location and volume of the infarction. Current CT technological innovat

Publikováno v: Journal of computer assisted tomography. 45(1)

OBJECTIVE We compared 40- to 70-keV virtual monoenergetic to conventional computed tomography (CT) perfusion reconstructions with respect to quality of perfusion maps. METHODS Conventional CT perfusion (CTP) images were acquired at 80 kVp in 25 patie
