Non-contrast T1 and T2 relaxometry characterizes reperfusion injury of acute MI in swine
Background Reperfusion injury in acute myocardial infarction (MI) results in edema, necrosis, microvascular obstruction (MVO), and intramyocardial hemorrhage (IMH), the latter presents an interesting clinical target. [1] Cardiovascular MRI has been shown capable of characterizing all of these tissue components. Other than MVO, which is currently detected by flow-deficient regions in contrast en...
متن کاملIntegrated treadmill stress testing and MR relaxometry (T1, T2, T2*): response in healthy calf muscles
Background Peripheral arterial disease (PAD) is accompanied by a complex lower limb pathophysiology resulting in reduced functional capacity and quality of life. We aim to characterize the exercise recovery kinetics in the calf muscle of healthy volunteers by combining treadmill exercise and magnetic resonance (MR) relaxometry (T1, T2 and T2*), and to investigate their relation with age and tre...

Pressure ulcers are localized areas of soft tissue breakdown due to mechanical loading. Susceptible individuals are subjected to pressure relief strategies to prevent long loading periods. Therefore, ischemia-reperfusion injury may play an important role in the etiology of pressure ulcers. To investigate the inter-relation between postischemic perfusion and changes in skeletal muscle integrity,...
متن کاملA statistical fMRI model for differential T2* contrast incorporating T1 and T2* of gray matter.
Relaxation parameter estimation and brain activation detection are two main areas of study in magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI). Relaxation parameters can be used to distinguish voxels containing different types of tissue whereas activation determines voxels that are associated with neuronal activity. In fMRI, the standard practice has been to dis...
متن کاملPre-Contrast Imaging of the Area At Risk in Acute Myocardial Infarction: T2 yields higher contrast than T1 MRI
Introduction: The area at risk (AAR) of infarction is the hypoperfused myocardial bed during coronary occlusion. The edematous AAR can be delineated in-vivo by T2 MRI and can be used in conjunction with delayed contrast enhancement to calculate myocardial salvage. T1 MRI has been recently used to image the edema associated with acute myocardial infarction. Objectives: We hypothesized that, due ...
