Tumor Arterial Input Function (AIF) estimation in DCE-MRI studies using a multiple reference tissue method
C. Yang, W. M. Stadler, M. Medved, G. S. Karczmar University of Chicago, Chicago, IL, United States Introduction: Accurate estimation of the arterial input function (AIF) is essential for quantitative analysis of DCE-MRI data. We have previously demonstrated that a common AIF can be estimated from the contrast agent concentration versus time curves (Ct(t)) in two reference tissues with differen...
متن کاملAn improved reference tissue approach for measuring the arterial input function in DCEMRI; comparison of late-phase reference tissue and plasma contrast media concentrations
Introduction: Analysis of dynamic contrast enhanced MRI (DCEMRI) data requires knowledge of the arterial input function (AIF), which accounts for variations in contrast media injection, cardiac output, and vascular function. The AIF can be determined from a major artery, a pre-defined ‘population’ function, or a reference tissue. However, the direct measurements from artery are subject to signi...
متن کاملPhase-based Contrast Agent Concentration Measurement for Determination of Mouse Arterial Input Function
Introduction: Dynamic Contrast Enhanced (DCE) MRI and pharmacokinetic modeling have shown promise for imaging tumours based on tissue vascularity [1]. The volume transfer function between the plasma and interstitial space, K, can be determined based on measurements of contrast agent concentration time-courses in these spaces [2]. The results of DCE-MRI are believed to have clinical significance...
متن کاملA new constrained blind estimation algorithm for determination of the arterial input function without reference tissues
Introduction: A major challenge in dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is the need to provide a measured estimate of the arterial input function (AIF) in order to perform pharmacokinetic modeling analysis of the resulting data. Measurement of the AIF requires the presence of a major artery in the imaging field-of-view, a significantly faster sampling rate than for tis...
متن کاملBlind estimation of the arterial input function in dynamic contrast-enhanced MRI using purity maximization.
Uncertainty in arterial input function (AIF) estimation is one of the major errors in the quantification of dynamic contrast-enhanced MRI. A blind source separation algorithm was proposed to determine the AIF by selecting the voxel time course with maximum purity, which represents a minimal contamination from partial volume effects. Simulations were performed to assess the partial volume effect...
