MRA scans can be performed with a contrast material or without. If required, the technologist administers the contrast material in a vein of your arm through a small intravenous (IV) catheter. The technologist may or may not inject a contrast dye into your forearm or hand to help improve th...

In contrast, a substantial drop of T2 relaxation times could be observed for the samples incubated with annexin V –CLIO. For all annexin V –CLIO concentra- tions, the T2 relaxation times of the camptothecin- treated samples (65% apoptotic cells) were substantial shorter compared with the non...
Whole-heart free breathing CINE acquisition was performed with the proposed approach in eight healthy subjects (age range: 21 to 35 years) and three patients (age range: 45 to 76 years) using a b-SSFP sequence. The acquisition was done on healthy subjects without the use of a contrast ...
These sequences include: Inhance Inflow IR is a non-contrast-enhanced MR angiography technique that has been developed to image arteries with ability to suppress static background tissue and venous flow. This sequence is based on 3D FIESTA, which improves SNR, as well as produce bright blood ...
scans with or without preprocessing: bias field correction, skull stripping, normalisation, etc. white matter lesions. SynthSeg was first presented for the automated segmentation of brain scans of any contrast and resolution. SynthSeg: Segmentation of brain MRI scans of any contrast and resolution wi...
MRI is normally applied with contrast agents to enhance the signal. Some contrast agents have been widely used for the early detection of disease, including Gd3+, Mn2+, superparamagnetic iron oxide nanoparticles (SPIONs) and other magnetic nanoparticles23,24,25,26,27,28,29,30,31,32. Contrast...
there are currently no raw MRI datasets involving the moving vocal tract. Previously published speech MRI datasets16,17,18,19,20(see Table1) have included reconstructed and processed images for a relatively small number of subjects. In contrast, this dataset provides a larger and more diverse set...

the volumes of blood–brain barrier disruption evaluated using contrast-enhancement T1-weighted imaging with Gadovist ( a gadolinium-based MRI contrast agent) were significantly more prominent in both the TBI and rmTBI rats on day 3, but not other time points after LFP. DTI noninvasively detects...
