We present an ultrahigh resolution in vivo human brain magnetic resonance imaging (MRI) dataset. It consists of T1-weighted whole brain anatomical data acquired at 7 Tesla with a nominal isotropic resolution of 250 μm of a single young healthy Caucas
Convolutional-recurrent neural networks approximate diffusion tractography from T1-weighted MRI and associated anatomical context - MASILab/cornn_tractography
Magnetic resonance imaging (MRI), which offers a number of advantages such as unlimited tissue penetration, zero ionizing radiation, and a noninvasive nature, has received considerable attention over the past two decades as a technique for clinical diagnosis. To improve imaging sensitivity, contrast ...
The as-prepared UIONPs act as T1-weighted MRI contrast agent due to the small-size effect (< 10 nm) [24], [25], [26]. UIONPs could be easily assembled into copper-encapsulating magnetic nanoassemblies (MNSs) due to the chelation effect with Cu2+. Interestingly, the positive MR signal...

Introduction Over the past decade, remarkable advancements in deep learning (DL) algorithms have led to a rapid transformation in the field of radiology. DL-aided diagnostics have achieved exceptional accuracy...
On the contrary, MRI demonstrates high signal intensity in comparison to CT scans. As a result, both anatomical and physiological information can be derived from MRI scans. In particular, both CT and MRI can provide accurate anatomical information about the liver lesion or haemangioma; however, ...
