Multimodality Imaging [PDF]

Stroke, 2004
Noninvasive “multimodal” in vivo imaging is not just becoming standard practice in the clinic, but is rapidly changing the evolving field of experimental imaging of genetic expression (“molecular imaging”). The development of multimodality methodology based on nuclear medicine (NM), positron emission tomography (PET) imaging, magnetic resonance imaging

Cryo-EM structures from sub-nl volumes using pin-printing and jet vitrification

Nature Communications, 2020
There is a need to further improve the automation of cryo-EM sample preparation to make it more easily accessible for non-specialists, reduce sample waste and increase reproducibility.

COVID-19 Detection Through Transfer Learning Using Multimodal Imaging Data

IEEE Access, 2020
Detecting COVID-19 early may help in devising an appropriate treatment plan and disease containment decisions. In this study, we demonstrate how transfer learning from deep learning models can be used to perform COVID-19 detection using images from three

Deconvolution of hemodynamic responses along the cortical surface using personalized functional near infrared spectroscopy

Scientific Reports, 2021
In functional near infrared spectroscopy (fNIRS), deconvolution analysis of oxy and deoxy-hemoglobin concentration changes allows estimating specific hemodynamic response functions (HRF) elicited by neuronal activity, taking advantage of the fNIRS ...

Multimodal Imaging of Microvascular Abnormalities in Retinal Vein Occlusion

Journal of Clinical Medicine, 2021
The technologies of ocular imaging modalities such as optical coherence tomography (OCT) and OCT angiography (OCTA) have progressed remarkably. Of these in vivo imaging modalities, recently advanced OCT technology provides high-resolution images, e.g ...

Myeloarchitecture gradients in the human insula: Histological underpinnings and association to intrinsic functional connectivity

NeuroImage, 2020
Insular cortex is a core hub involved in multiple cognitive and socio-affective processes. Yet, the anatomical mechanisms that explain how it is involved in such a diverse array of functions remain incompletely understood.

Mass spectrometry imaging identifies altered hepatic lipid signatures during experimental Leishmania donovani infection

Frontiers in Immunology, 2022
IntroductionSpatial analysis of lipids in inflammatory microenvironments is key to understand the pathogenesis of infectious disease. Granulomatous inflammation is a hallmark of leishmaniasis and changes in host and parasite lipid metabolism have been ...
