Subtraction in View-Shared 3D Contrast-Enhanced MRA
INTRODUCTION The use of a pre-contrast reference image, referred to as a mask, to suppress background signal and improve output contrast-to-noise ratio (CNR) through subtraction is common in contrast-enhanced MR angiography. It is critical that this operation be performed to optimize output image quality. As has been previously reported [1-3] it is advantageous to use complex subtraction for th...
متن کاملCBCT-based 3D MRA and angiographic image fusion and MRA image navigation for neuro interventions
Digital subtracted angiography (DSA) remains the gold standard for diagnosis of cerebral vascular diseases and provides intraprocedural guidance. This practice involves extensive usage of x-ray and iodinated contrast medium, which can induce side effects. In this study, we examined the accuracy of 3-dimensional (3D) registration of magnetic resonance angiography (MRA) and DSA imaging for cerebr...
متن کامل3D contrast-enhanced MRA of the runoff vessels: value of image subtraction
Introduction: Diagnostic accuracy and cost will determine the success of contrast-enhanced 3D MRA in replacing catheter-based digital subtraction angiography (DSA) as the modality of choice for assessing the peripheral run-off arteries. Image subtraction, proposed by some investigators as a way to enhance diagnostic accuracy (1) lengthens data acquisition and post-processing times and therefore...

Carroll Biomedical Engineering, Northwestern University, Chicago, IL, United States, Radiology, Northwestern University Feinberg School of Medicine, Chicago, IL, United States Introduction Multi-phase angiography is necessary for the diagnosis of vascular disorders involving arteriovenous shunting, retrograde flow, and collat...
متن کاملA 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...
