The Emerging Role of Multimodality Imaging in the Diagnosis and Management of Post Pericardiotomy Syndrome.
Curr Cardiol Rep
January 2025
Division of Cardiology, McGill University Health Centre, 845 Rue Sherbrooke O, Montreal, QC, H3H 0G4, Canada.
Purpose Of Review: This review aims to evaluate current diagnostic and therapeutic strategies for postpericardiotomy syndrome (PPS), with a focus on the evolving role of multimodality imaging, including echocardiography, cardiac computed tomography (CCT), and cardiac magnetic resonance imaging (CMR). The review also explores the potential benefits of advanced imaging in improving the accuracy and management of PPS.
Recent Findings: PPS, a common complication following cardiac surgery, presents with pleuritic chest pain, fever, and pericardial or pleural effusion.
Transmantle pressure under the influence of free breathing: non-invasive quantification of the aqueduct pressure gradient in healthy adults.

Background: The pressure gradient between the ventricles and the subarachnoid space (transmantle pressure) is crucial for understanding CSF circulation and the pathogenesis of certain neurodegenerative diseases. This pressure can be approximated by the pressure difference across the aqueduct (ΔP). Currently, no dedicated platform exists for quantifying ΔP, and no research has been conducted on the impact of breathing on ΔP.

Department of Radiology, Mayo Clinic, Rochester, MN, USA. Electronic address:
Cardiorespiratory signals have long been treated as "noise" in functional magnetic resonance imaging (fMRI) research, with the goal of minimizing their impact to isolate neural activity. However, there is a growing recognition that these signals, once seen as confounding variables, provide valuable insights into brain function and overall health. This shift reflects the dynamic interaction between the cardiovascular, respiratory, and neural systems, which together support brain activity.

Neurol Sci
January 2025
Neuroradiology Unit, Azienda Unità Sanitaria Locale-IRCCS di Reggio Emilia, Via Amendola 2, Reggio Emilia, 42122, Italy.
Introduction: Large artery atherosclerosis is a relevant cause of ischemic stroke. Beyond carotid artery stenosis ≥ 50%, causative in etiological classification of stroke, non-stenosing plaques are an increasingly reported cause of stroke with embolic pattern.
Methods: We are presenting the case of a 56 years old woman presenting with a first symptomatic multifocal ischemic stroke in the right internal carotid artery (ICA) territory on 2018 and a finding of asymptomatic past vascular injury in the same vascular territory on neuroimaging studies.

Alzheimers Dement
December 2024
Sunnybrook Health Sciences Centre, Toronto, ON, Canada.
Background: White matter hyperintensities (WMH) are commonly observed on MRI in Alzheimer's disease (AD), but the molecular pathways underlying their relationships with the ATN biomarkers remain unclear. The aim of this study was to identify genetic variants that may modify the relationship between WMH and the ATN biomarkers.
Method: This genome-wide interaction study (GWIS) included individuals with AD, MCI, and normal cognition from ADNI (n = 1012).
