Association Between Fetal Myocardial Alterations and Congenital Heart Disease Based on Post‐Mortem Myocardial MRI

iRADIOLOGY, EarlyView.
Applying myocardial parametric mapping based on post‐mortem MRI is feasible for non‐invasive tissue characterization. We speculated that the elevated T2 relaxation may be an essential myocardial tissue characterization of cyanotic congenital heart disease, potentially suggesting myocardial edema, which may provide evidence to guide appropriate ...

Investigating the Impact of Arterial Irregularity On Clinical Parameters Using Reduced Order CFD Models In Stenosed Coronary Artery [PDF]

arXiv
Coronary heart disease (CHD) remains a leading cause of mortality worldwide. This study introduces a novel approach that integrates patient-specific Multi-slice CT scans into CAD models, using a one-dimensional numerical framework to assess varying degrees of coronary artery stenosis.

The Diagnostic Value of Contrast‐Enhanced Vessel Wall MRI for Diagnosing Neuropsychiatric Systemic Lupus Erythematosus

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Imaging biomarkers for neuropsychiatric systemic lupus erythematosus (NPSLE) are highly needed, and intracranial contrast‐enhanced vessel wall imaging (CE‐VWI) can potentially detect cerebral vessel wall abnormalities in lupus. Purpose To evaluate the diagnostic value of CE‐VWI in differentiating NPSLE from non‐NPSLE.

Renal artery bypass including aortic graft for renovascular hypertension

Journal of Pediatric Surgery Case Reports, 2019
Background: Renal artery stenosis (RAS) is a rare renal manifestation of tuberous sclerosis (TS). In children, it leads to renovascular hypertension that can be managed medically or surgically.

“MR Fingerprinting for Imaging Brain Hemodynamics and Oxygenation”

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Over the past decade, several studies have explored the potential of magnetic resonance fingerprinting (MRF) for the quantification of brain hemodynamics, oxygenation, and perfusion. Recent advances in simulation models and reconstruction frameworks have also significantly enhanced the accuracy of vascular parameter estimation.

Myocardial Region-guided Feature Aggregation Net for Automatic Coronary artery Segmentation and Stenosis Assessment using Coronary Computed Tomography Angiography [PDF]

arXiv
Coronary artery disease (CAD) remains a leading cause of mortality worldwide, requiring accurate segmentation and stenosis detection using Coronary Computed Tomography angiography (CCTA). Existing methods struggle with challenges such as low contrast, morphological variability and small vessel segmentation.

Computational Assessment of Hemodynamics in Asymmetric-type Lesion of Idealized Coronary Stenoses [PDF]

arXiv
Coronary artery stenosis, characterized by the narrowing of the lumen, significantly affects blood flow and contributes to the progression of cardiovascular diseases. This study investigates the hemodynamics of coronary artery models with varying stenosis configurations, all maintaining an 80% lumen reduction, to determine how differences in morphology
