Open AccessMyocardial glucose suppression may interfere with the detection of inflammatory cells with FDG-PET as suggested in a canine model of myocardial infarction
After myocardial infarction, fibrosis and an ongoing dysregulated inflammatory response have been shown to lead to adverse cardiac remodeling. FDG PET is an imaging modality sensitive to inflammation as long a...

Open AccessIntramyocardial hemorrhage drives fatty degeneration of infarcted myocardium
Sudden blockage of arteries supplying the heart muscle contributes to millions of heart attacks (myocardial infarction, MI) around the world. Although re-opening these arteries (reperfusion) saves MI patients ...

Open AccessAssessment of intramyocardial hemorrhage with dark-blood T2*-weighted cardiovascular magnetic resonance
Intramyocardial hemorrhage (IMH) within myocardial infarction (MI) is associated with major adverse cardiovascular events. Bright-blood T2*-based cardiovascular magnetic resonance (CMR) has emerged as the refe...

Open AccessImproved PET/MRI accuracy by use of static transmission source in empirically derived hardware attenuation correction
Accurate quantification of radioactivity, measured by an integrated positron emission tomography (PET) and magnetic resonance imaging (MRI) system, is still a challenge. One aspect of such a challenge is to co...

The Effect of Registration on Voxel-Wise Tofts Model Parameters and Uncertainties from DCE-MRI of Early-Stage Breast Cancer Patients Using 3DSlicer
We quantitatively investigate the influence of image registration, using open-source software (3DSlicer), on kinetic analysis (Tofts model) of dynamic contrast enhanced MRI of early-stage breast cancer patient...

Open Access18F-FDG PET-guided diffusion tractography reveals white matter abnormalities around the epileptic focus in medically refractory epilepsy: implications for epilepsy surgical evaluation
Hybrid PET/MRI can non-invasively improve localization and delineation of the epileptic focus (EF) prior to surgical resection in medically refractory epilepsy (MRE), especially when MRI is negative or equivoc...

Article
Open AccessEvaluation of 511 keV photon attenuation by a novel 32-channel phased array prospectively designed for cardiovascular hybrid PET/MRI imaging
Simultaneous cardiovascular imaging with positron emission tomography (PET) and magnetic resonance imaging (MRI) requires tools such as radio frequency (RF) phased arrays to achieve high temporal and spatial r...

Open AccessHepcidin-mediated Iron Regulation in P19 Cells is Detectable by Magnetic Resonance Imaging
Magnetic resonance imaging can be used to track cellular activities in the body using iron-based contrast agents. However, multiple intrinsic cellular iron handling mechanisms may also influence the detection ...

Open AccessAssessment of a novel 32-channel phased array for cardiovascular hybrid PET/MRI imaging: MRI performance
Cardiovascular imaging using hybrid positron emission tomography (PET) and magnetic resonance imaging (MRI) requires a radio frequency phased array resonator capable of high acceleration factors in order to ac...

Article
Open AccessRotations of macromolecules affect nonspecific biological responses to magnetic fields
We have previously proposed that there are at least two initial molecular transduction mechanisms needed to explain specific and nonspecific biological effects of weak magnetic fields. For the specific effect ...

Forming Magnetosome-Like Nanoparticles in Mammalian Cells for Molecular MRI
To identify molecular activities that define the early stages of disease progression, there is a critical need to noninvasively image these processes. For this, the magnetosome is an ideal structure by which c...

Imaging Tumor Growth Non-invasively Using Expression of MagA or Modified Ferritin Subunits to Augment Intracellular Contrast for Repetitive MRI
The bacterial gene MagA imparts magnetic properties to mammalian cells and provides a basis for cell tracking by magnetic resonance imaging (MRI). In a mouse model of tumor growth from transplanted cells, we used...

Open AccessComparison of the myocardial clearance of endothelial progenitor cells injected early versus late into reperfused or sustained occlusion myocardial infarction
Stem cell transplantation following AMI has shown promise for the repair or reduction of the amount of myocardial injury. There is some evidence that these treatment effects appear to be directly correlated to...

The response of the human circulatory system to an acute 200-μT, 60-Hz magnetic field exposure
Recent research by the authors on the effects of extremely low-frequency (ELF) magnetic field (MF) exposure on human heart rate (HR), heart rate variability (HRV), and skin blood perfusion found no cardiovascu...
