Renal Metabolic Rate of Oxygen in Response to Hypoxia Challenges by Means of Quantitative MRI in Humans Open
In early kidney disease, tissue hypoxia occurs due to an imbalance between ATP supply and demand. Whole‐organ renal metabolic rate of oxygen (rMRO 2 ) is therefore a potential biomarker for assessing renal function. This study evaluated th…

<span>DREAMER</span> : Rapid and Simultaneous Multiple Contrast Magnetic Resonance Imaging of Solid and Soft Tissue Open
Purpose Pediatric craniofacial imaging may involve examination of both the skull and brain tissues via CT and MRI, respectively. DREAMER (Dual Repetition and Echo Acquisition with Multi‐contrast Encoding and Reconstruction) simultaneously …

<span>MRI</span> ‐based quantification of whole‐organ renal metabolic rate of oxygen during free‐breathing Open
Purpose Renal metabolic rate of oxygen (rMRO 2 ) reflects the kidney's metabolic efficiency, making it a potential biomarker for early‐stage kidney disease. This study introduces an ungated, free‐breathing MRI sequence in comparison to its…

Three contrasts in 3 min: Rapid, high‐resolution, and bone‐selective <span>UTE MRI</span> for craniofacial imaging with automated deep‐learning skull segmentation Open
Purpose Ultrashort echo time (UTE) MRI can be a radiation‐free alternative to CT for craniofacial imaging of pediatric patients. However, unlike CT, bone‐specific MR imaging is limited by long scan times, relatively low spatial resolution,…

Quantification of whole‐organ individual and bilateral renal metabolic rate of oxygen Open
Purpose Renal metabolic rate of oxygen (rMRO 2 ) is a potentially important biomarker of kidney function. The key parameters for rMRO 2 quantification include blood flow rate (BFR) and venous oxygen saturation (SvO 2 ) in a draining vessel…

Correspondence of functional connectivity gradients across human isocortex, cerebellum, and hippocampus Open
Gradient mapping is an important technique to summarize high dimensional biological features as low dimensional manifold representations in exploring brain structure-function relationships at various levels of the cerebral cortex. While re…

MRI Quantification of Cortical Bone Porosity, Mineralization, and Morphologic Structure in Postmenopausal Osteoporosis Open
Background Preclinical studies have suggested that solid-state MRI markers of cortical bone porosity, morphologic structure, mineralization, and osteoid density are useful measures of bone health. Purpose To explore whether MRI markers of …

Functional connectivity gradients as a common neural architecture for predictive processing in the human brain Open
Predictive processing is emerging as a common computational hypothesis to account for diverse psychological functions subserved by a brain, providing a systems-level framework for characterizing structure-function relationships of its dist…

Segmentation of Infrared Breast Images Using MultiResUnet Neural Network Open
Breast cancer is the second leading cause of death for women in the U.S. Early detection of breast cancer is key to higher survival rates of breast cancer patients. We are investigating infrared (IR) thermography as a noninvasive adjunct t…

Investigating the relationship between emotional granularity and cardiorespiratory physiological activity in daily life Open
Emotional granularity describes the ability to create emotional experiences that are precise and context-specific. Despite growing evidence of a link between emotional granularity and mental health, the physiological correlates of granular…
