Learning intervention-induced deformations for non-rigid MR-CT registration and electrode localization in epilepsy patients

NeuroImage: Clinical, 2016
This paper describes a framework for learning a statistical model of non-rigid deformations induced by interventional procedures. We make use of this learned model to perform constrained non-rigid registration of pre-procedural and post-procedural ...

Mapping of exogenous choline uptake and metabolism in rat glioblastoma using deuterium metabolic imaging (DMI)

Frontiers in Cellular Neuroscience, 2023
IntroductionThere is a lack of robust metabolic imaging techniques that can be routinely applied to characterize lesions in patients with brain tumors. Here we explore in an animal model of glioblastoma the feasibility to detect uptake and metabolism of ...

MS‐CT Coronary Imaging

Journal of Interventional Cardiology, 2003
Magnetic resonance imaging and computed tomography (CT) have recently emerged as two techniques that can noninvasively visualize the coronary arteries. The latest generation 16‐row detector multislice CT scanner is now considered the most reliable technique to visualize the coronaries.

Pneumatosis: Appearances on CT Imaging

Cureus, 2023
Pneumatosis is a general term used to designate the presence of spontaneous air or gas leaks into the body's compartments.In this paper, we provide an overview of gas originating from different sites and present the most common routes by which air may escape free to surrounding or distant tissues.On the basis of 45 interesting clinical cases, we ...

Imaging Hallmarks of the Tumor Microenvironment in Glioblastoma Progression

Frontiers in Oncology, 2021
Glioblastoma progression involves multifaceted changes in vascularity, cellularity, and metabolism. Capturing such complexities of the tumor niche, from the tumor core to the periphery, by magnetic resonance imaging (MRI) and spectroscopic imaging (MRSI)
