Progression is variable, but over time, seems to become more widespread with microglial activation associated with extensive chronic neurodegeneration and persistent disability. Magnetic resonance imaging (MRI), with and without contrast, has become the standard metric of finding and following lesions and...
MRI contrast is invaluable when imaging tumors in major body organs like your brain or in your central nervous system. MRI dye can help doctors detect the tumors, identify if they’re malignant or benign and determine the growth stage they are in. What’s Involved With Contrast Injection? Mos...
This work proposes a novel MRI method - Intrinsic Diffusivity Encoding of Arterial Labeled Spin (IDEALS) - for the whole-brain mapping of water permeability in the human brain without an exogenous contrast agent. Quantitative separation of the intravascular and extravascular labeled water MRI signal ...
Automatic contrast enhancement of brain MR images using Average Intensity Replacement based on Adaptive Histogram Equalization (AIR-AHE) Medical imaging is the most established technique of visualizing the interior of the human body without the risk of the non-invasive effect. This technolog... IS Is...
Our purpose was to compare prospectively the sensitivity of contrast-enhanced magnetisation transfer (MT) MRI and gradient-echo (GE) T1-weighted images in metastatic disease of the brain. We studied 52 patients with brain metastases, using conventional T1-weighted GE and MT spin-echo (SE) images...
As these measures can reflect the integrity of the blood-brain barrier and tumor vascular perfusion and permeability, these features may also reflect features that are associated with different tumor grades. Several studies have suggested that high-grade gliomas have greater vascular permeability, possibl...
In magnetic resonance imaging (MRI), contrast agents are used to enhance the imaging of tissue structures. While they enhance signals in blood vessels and in spaces between cells, they do not reach the interior of the cell. By contrast, glucose is taken
Most MRIs are performed without a contrast dye because it isn't needed to get accurate results for the suspected problem. Also, certain patients (those who are pregnant as well as those withkidney disease) shouldn't get the contrast dye because of possible complications. ...
Doctors may order MRI scans to help diagnose multiple sclerosis, brain tumors, torn ligaments, tendonitis, cancer and strokes, to name just a few. An MRI scan is the best way to see inside the human body without cutting it open. That may be little comfort to you when you're getting ...
