Dynamic Contrast Enhanced MRI (DCE-MRI): From the Simplest to the Most Advanced DCE-Model
1. Tracer Kinetic Modeling • Extracellular agents (such as Gd-DTPA) accumulate in the interstitium of many tissues (e.g. muscle) but do not cross the healthy blood-brain-barrier. • Functional information may be obtained by treating Gd-DTPA as a tracer and following its kinetics (as opposed to the conventional ‘static’ approach, inject wait – image once). • After intravenous administration (norm...
متن کاملIntegration of DCE-MRI and DW-MRI Quantitative Parameters for Breast Lesion Classification
OBJECTIVE The purpose of our study was to evaluate the diagnostic value of an imaging protocol combining dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted MRI (DW-MRI) in patients with suspicious breast lesions. MATERIALS AND METHODS A total of 31 breast lesions (15 malignant and 16 benign proved by histological examination) in 26 female patients were included in this study. For ...
متن کاملCan Dynamic Contrast-Enhanced MRI (DCE-MRI) and Diffusion-Weighted MRI (DW-MRI) Evaluate Inflammation Disease
The aim of the study was to investigate diagnosis efficacy of dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted MRI (DW-MRI) in Crohn's disease (CD). To find out the correlations between functional MRI parameters including K, Kep, Ve, Vp, and apparent diffusion coefficient (ADC) with a serologic biomarker. The relationships between pharmacokinetic parameters and ADC were also studi...
متن کاملQuantifying heterogeneity of lesion uptake in dynamic contrast enhanced MRI for breast cancer diagnosis
The current study investigates whether texture features extracted from lesion kinetics feature maps can be used for breast cancer diagnosis. Fifty five women with 57 breast lesions (27 benign, 30 malignant) were subjected to dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) on 1.5T system. A linear-slope model was fitted pixel-wise to a representative lesion slice time series and f...
متن کاملPharmacokinetic mapping for lesion classification in dynamic breast MRI.
PURPOSE To prospectively investigate whether a rapid dynamic MRI protocol, in conjunction with pharmacokinetic modeling, could provide diagnostically useful information for discriminating biopsy-proven benign lesions from malignancies. MATERIALS AND METHODS Patients referred to breast biopsy based on suspicious screening findings were eligible. After anatomic imaging, patients were scanned us...
