Hibernating myocardium signal increase which can be visualised with the "late gadolinium enhancement technique". This is probably the most accurate way to visualise scarred myocardium. An alternative (or additional) technique with CMR is the use of low dose dobutamine similar to echocardiography. PET: The finding of a perfusion or metabolic mismatch between PET-FDG and PET-NH is indicative of decreased metabolism. The wall of the affected segments is hypo-, a-, or dyskinetic. The phenomenon is highly significant clinically because it usually manifests itself in the setting of chronic ischemia, that is potentially reversible by revascularisation via cardiac catheterization. The regions of myocardium are
Cooperative Human Tissue Network given for 2008 through 2013, and the sixth for 2014-2019, with supplemental funding bridging the years in between grants. The name was changed in 2014 to the "Collaborative" Human Tissue Network. The CHTN obtains biospecimens from routine diagnostic or therapeutic surgical resections and autopsies, which otherwise would be discarded. Malignant, benign, diseased and normal biospecimens are collected and distributed to both national and international investigators. In addition, remnant body fluids are available on some patients and limited histological services can be obtained by special arrangement. Requests for large sample sizes, large numbers of biospecimens, rare biospecimens or biospecimens in high
