Estimating kinetic parameters from dynamic contrast‐enhanced t1‐weighted MRI of a diffusable tracer: Standardized quantities and symbols
We describe a standard set of quantity names and symbols related to the estimation of kinetic
parameters from dynamic contrast‐enhanced T 1 ‐weighted magnetic resonance imaging …

4D‐CT imaging of a volume influenced by respiratory motion on multi‐slice CT
We propose a new scanning protocol for generating 4D‐CT image data sets influenced by
respiratory motion. A cine scanning protocol is used during data acquisition, and two …

An adiabatic approximation to the tissue homogeneity model for water exchange in the brain: I. Theoretical derivation
KSS Lawrence, TY Lee - Journal of Cerebral Blood Flow & …, 1998 - journals.sagepub.com
Using the adiabatic approximation, which assumes that the tracer concentration in parenchymal
tissue changes slowly relative to that in capillaries, we derived a time-domain, closed-…
