Having an MRI with contrast may lead to some side effects and safety concerns, including those below. Kidney Issues If you have healthy kidneys, you’ll excreteas much as 98% of the contrast mediumbefore it breaks down. However, if you’re having problems with your kidneys and they’re no...
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...
This novel agent, based on the essential nutrient manganese, has strong potential as a safer alternative to currently used contrast agents

Synchronous assessment of multiple MRI contrast agents in a single scanning session would provide a new “multi-color” imaging capability similar to fluorescence imaging but with high spatiotemporal resolution and unlimited imaging depth. This multi-age
Brain vasculature is conventionally represented as straight cylinders when simulating blood oxygenation level dependent (BOLD) contrast effects in functional magnetic resonance imaging (fMRI). In reality, the vasculature is more complicated with branchin

The study was performed with a 1.5-Tesla device and characterised by three phases: the first phase without contrast material (unenhanced MRI), the second after the administration of ferumoxides (SPIO-MRI), and the third, a double-contrast study following the injection of a bolus of ...
Each image is matched with an average template of the same modality (or the closest available with similar contrast, from the same templates used in mri_reface) and the template is used to “fill in” missing face parts using the pieces from the template. This operation is analogous to ...
PURPOSE: The aim of this study was to compare the performance of double-contrast magnetic resonance imaging (DC-MRI) with the sequential use of superparamagnetic iron oxide (SPIO) and gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) contrast agents compared with unenhanced MRI and SPIO-enhanced...
