AI Article Synopsis

  • The standard treatment for brain tumors involves surgically removing as much of the tumor as possible, but challenges like brain shift make this difficult.
  • Intraoperative imaging techniques like iMRI and iUS can assist in visualizing brain tumors during surgery, with iUS being quicker but less detailed than iMRI.
  • A newly released extensive database of MRI and iUS images from surgical cases aims to improve brain tumor research, enhance neurosurgical training, and facilitate AI advancements in medical imaging.

Article Abstract

The standard of care for brain tumors is maximal safe surgical resection. Neuronavigation augments the surgeon's ability to achieve this but loses validity as surgery progresses due to brain shift. Moreover, gliomas are often indistinguishable from surrounding healthy brain tissue. Intraoperative magnetic resonance imaging (iMRI) and ultrasound (iUS) help visualize the tumor and brain shift. iUS is faster and easier to incorporate into surgical workflows but offers a lower contrast between tumorous and healthy tissues than iMRI. With the success of data-hungry Artificial Intelligence algorithms in medical image analysis, the benefits of sharing well-curated data cannot be overstated. To this end, we provide the largest publicly available MRI and iUS database of surgically treated brain tumors, including gliomas (n = 92), metastases (n = 11), and others (n = 11). This collection contains 369 preoperative MRI series, 320 3D iUS series, 301 iMRI series, and 356 segmentations collected from 114 consecutive patients at a single institution. This database is expected to help brain shift and image analysis research and neurosurgical training in interpreting iUS and iMRI.

This study investigates the impact of gamification on response inhibition in a Stop-Signal Task (SST) and examines participants' gamification experience. The findings reveal that, after accounting for approach- and avoidance-motivation as well as impulsiveness, higher immersion is associated with impaired response inhibition. This effect could be attributed to a substantial decline in immersion between the first and second SST sessions.

Traumatic Brain Injury (TBI) is a devastating cause of death and disability. Outcomes following TBI have been extensively studied; however, less attention has been given to identifying characteristics of individuals who have a favorable outcome following severe TBI. We conducted a retrospective analysis of a database containing information on TBI patients admitted to a level 1 trauma center between 2015 and 2021.

The paradox of the self-studying brain.

Phys Life Rev

Wellcome Trust Centre for Neuroimaging, Institute of Neurology, University College London, UK; VERSES AI Research Lab, Los Angeles, CA, 90016, USA.

The paradox of a brain trying to study itself presents a conundrum, raising questions about self-reference, consciousness, psychiatric disorders, and the boundaries of scientific inquiry. By which means can this complex organ shift the focus of study towards itself? We aim at unpacking the intricacies of this paradox. Historically, this question has been raised by philosophers under different frameworks.

Distributed model building and recursive integration for big spatial data modeling.

Biometrics

January 2025

Department of Biostatistics, Brown University, Providence, RI 02912, United States.

Motivated by the need for computationally tractable spatial methods in neuroimaging studies, we develop a distributed and integrated framework for estimation and inference of Gaussian process model parameters with ultra-high-dimensional likelihoods. We propose a shift in viewpoint from whole to local data perspectives that is rooted in distributed model building and integrated estimation and inference. The framework's backbone is a computationally and statistically efficient integration procedure that simultaneously incorporates dependence within and between spatial resolutions in a recursively partitioned spatial domain.
