MR‐zero meets RARE MRI: Joint optimization of refocusing flip angles and neural networks to minimize T2‐induced blurring in spin echo sequences

Magnetic Resonance in Medicine, Volume 90, Issue 4, Page 1345-1362, October 2023., 2023
Purpose An end‐to‐end differentiable 2D Bloch simulation is used to reduce T2 induced blurring in single‐shot turbo spin echo sequences, also called rapid imaging with refocused echoes (RARE) sequences, by using a joint optimization of refocusing flip angles and a convolutional neural network.

Clinical use of a new frameless optical neuronavigation system for brain biopsies: 10 cases (2013–2020)

Journal of Small Animal Practice, Volume 63, Issue 6, Page 468-481, June 2022., 2022
Objectives The aim of the retrospective study was to describe the brain biopsy procedure using a new frameless optical neuronavigation system and to report diagnostic yield and complications associated with the procedure. Materials and Methods The medical records for all dogs with forebrain lesions that underwent brain biopsy with a frameless optical ...

Learn to interpret voltage maps: an atlas of topographies

Epileptic Disorders, Volume 24, Issue 2, Page 229-248, April 2022., 2022
Abstract Describing the location of EEG abnormalities, such as interictal epileptiform discharges, is an important step in the interpretation of EEG recordings and has clinical relevance, as it is expected to point out the region of the brain generating these abnormal signals.

Pupillometry tracks cognitive load and salience network activity in a working memory functional magnetic resonance imaging task

Human Brain Mapping, Volume 43, Issue 2, Page 665-680, February 1, 2022., 2022
The present report is a combined functional magnetic resonance imaging/pupillometry study investigating neural correlates of pupil fluctuations during working memory processing. We showed that pupil size between task conditions with varying working memory load correlates with the frontoparietal network and pupil change within conditions correlates with

Nucleus accumbens projections: Validity and reliability of fiber reconstructions based on high‐resolution diffusion‐weighted MRI

Human Brain Mapping, Volume 42, Issue 18, Page 5888-5910, December 15, 2021., 2021
The nucleus accumbens (NAc), as a mesolimbic and dopaminergic relay station, and its efferent and afferent fiber‐projections play a central role within neuronal networks whose functions are impaired in various underlying neuro‐psychiatric disorders and could therefore be effective targets for the treatment of these disorders using deep brain ...

Multiple system aging‐related tau astrogliopathy with complex proteinopathy in an oligosymptomatic octogenarian

Neuropathology, Volume 41, Issue 1, Page 72-83, February 2021., 2021
The combination of multiple neurodegenerative proteinopathies is increasingly recognized. Together they can potentiate neuronal dysfunction and contribute to complex neurological symptoms. We report an octogenarian female case of multiple extraneural metastases of a rectal carcinoma.

Cingulate gyrus: anatomy, physiology and epileptic seizure

Chinese Journal of Contemporary Neurology and Neurosurgery, 2018
The cingulate gyrus is crescent?shaped convolution on the medial surface of cerebral hemisphere between cingulate sulcus and corpus callosum. Cingulate gyrus is an integral component of the limbic system and Papez's circuit, including anterior cingulate ...
