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 excrete as much as 98% of the contrast medium before it breaks down. However, if you’re having problems with your kidneys and they’re...
The fact that MRI systems don’t use ionizing radiation, as other imaging devices do, is a comfort to many patients, as is the fact that MRI contrast materials have a very low incidence of side effects. Most facilities prefer not to image pregnant women, due to limited research of the ...
(iVASO-DS)' MRI approach is presented where aCBV (mL blood/100 mL parenchyma) is quantified without contrast agents using the difference between ... MJ Donahue,E Sideso,BJ Macintosh,... - 《Journal of Cerebral Blood Flow & Metabolism Official Journal of the International Society of Cerebr...
8. Despite being trained on a different body region, field strength, and image contrast, our model demonstrates remarkable adaptability, effectively reducing image noise while preserving detailed structures and edges. In contrast, the model trained using the Noise2Void principle shows a noticeable loss...
In the second row, an example of PI-RADS 3 lesion not confirmed at biopsy: mpMRI showed reduced T2 signal intensity in the right PZ (D), altered diffusivity at b1000 DWI (E) without contrast enhancement (F). PI-RADS prostate imaging-reporting and data system, mpMRI multiparametric MRI,...
we did not examine effects on measurements from any structures outside the brain; de-facing directly modifies regions in the face and neck, and when these regions are of primary research interest, dataset managers would likely consider alternative means to protect participant privacy without de-fac...
Gadolinium-based contrast agents, as the most commonly used contrast agents, are expensive and may have potential side effects, and it is desired to obtain contrast-enhanced brain tumor MRI scans without the actual use of contrast agents. Deep learning methods have been applied to synthesize ...
Under these constant conditions in model training and image evaluation, pixel value consistency with the original MR image in the air region (outside the head) was superior in the results of CGAN. In contrast, the correction image by U-net degraded the pixel value restorability, particularly ...
Cochlear implantation is a standard treatment option due to expanding indications. Cranial magnetic resonance imaging (cMRI) has become a widespread diagnostic tool. Therefore, an increased number of cochlear implant (CI) users are undergoing cMRI scans.
