Automatic 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...

A contrast analysis approach to change

This paper presents the foundations of contrast analysis as a method for examining change. Contrast analysis is a relatively high-powered, simple, and informative procedure for evaluating hypotheses about specific patterns of change. This paper reviews the general purpose and nature of contrast analysis, it discusses some of the advantages of contrast analysis as a method for examining change, ...

Attending to Contrast

stimulus that drives the neuron to fire and can be a meaningful way to characterize a neuron's responses. However, by studying the full distribution of stimuli preceding a spike rather than just the average of this distribution , the authors show that quickly varying dynamic stimuli have a more subtle effect on H1, so that there Attending to Contrast are essentially two relevant functions of th...

A new approach to contrast enhancement in MAGICA gel dosimeter image with MRI technique

parameters that have to be measured in gel dosimetry. However, the resolution in gel is strongly dependant on gel composition. Selection of optimum method in dose response readout and proper values of parameters can result in noise reduction as well as improvement of contrast, and spatial resolution considerably. Materials and Methods: MAGICA polymer gel dosimeters were manufactured and irradia...
