Direct estimation of tracer-kinetic parameter maps from highly undersampled brain dynamic contrast enhanced MRI.
PURPOSE The purpose of this work was to develop and evaluate a T1 -weighted dynamic contrast enhanced (DCE) MRI methodology where tracer-kinetic (TK) parameter maps are directly estimated from undersampled (k,t)-space data. THEORY AND METHODS The proposed reconstruction involves solving a nonlinear least squares optimization problem that includes explicit use of a full forward model to conver...
متن کاملQuantifying spatial heterogeneity in dynamic contrast-enhanced MRI parameter maps.
Dynamic contrast-enhanced MRI is becoming a standard tool for imaging-based trials of anti-vascular/angiogenic agents in cancer. So far, however, biomarkers derived from DCE-MRI parameter maps have largely neglected the fact that the maps have spatial structure and instead focussed on distributional summary statistics. Such statistics-e.g., biomarkers based on median values-neglect the spatial ...
متن کاملHighly Accelerated Brain DCE MRI with Direct Estimation of Pharmacokinetic Parameter Maps
INTRODUCTION: In T1-weighted dynamic contrast enhanced (DCE) MRI, pharmacokinetic (PK) parameter maps (e.g. K, abbreviated Kt, and vp) are derived from the dynamic image series and used for diagnostic purpose. In accelerated DCE MRI, anatomic image series are typically reconstructed from under-sampled (k,t)-space first, then fit into a PK model to derive the parameter maps [1]. We call this the...
متن کاملAutomatic Prostate Cancer Segmentation Using Kinetic Analysis in Dynamic Contrast-Enhanced MRI
Background: Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) provides functional information on the microcirculation in tissues by analyzing the enhancement kinetics which can be used as biomarkers for prostate lesions detection and characterization.Objective: The purpose of this study is to investigate spatiotemporal patterns of tumors by extracting semi-quantitative as well as w...
متن کاملParameter estimation and change-point detection from Dynamic Contrast Enhanced MRI data using stochastic differential equations.
Dynamic Contrast Enhanced imaging (DCE-imaging) following a contrast agent bolus allows the extraction of information on tissue micro-vascularization. The dynamic signals obtained from DCE-imaging are modeled by pharmacokinetic compartmental models which integrate the Arterial Input Function. These models use ordinary differential equations (ODEs) to describe the exchanges between the arterial ...
