Perfusion imaging by PET to assess stenosis significance coronary stenosis depends on the reduced ability to increase myocardial blood flow by reserve vasodilation at the arteriolar level . By arteriolar autoregulation coronary flow reserve follows the myocardial demand, in other words, coronary circulation remains at a constant level with either decr

Contrast enhanced magnetic resonance imaging for assessing myocardial perfusion and reperfusion injuic heart disease and to assess their effects. These interventions relieve coronary artery stenoses that produce myocardial ischemia, and improve myocardial perfusion after thrombolytic therapy. New fast and ultra-fast magnetic resonance imaging (MRI) techniques have ameliorated previous limitations

MRI as a substitute for scintigraphic techniques in the assessment of inducible ischaemia in association with angina was first described early this century, despite the poorly understood physiological cause. The overall results for the detection of coronary artery disease by exercise electrocardiography are mediocre with an 81% sensitivity and 66% specificity , and the site of ST seg

Assessment of viability by MR-techniquessonance imaging (MRI) seems ideally suited to detect the regional wall thinning associated chronic myocardial scar . In contrast to akinetic and thinned transmural . infarcts , . infarcted myocardium may be transmurally necrotic and akinetic but may not yet exhibit myocardial thinning .

Assessment of viability in severely hypokinetic myocardium before revascularization and prediction o retention require tracer delivery through adequate perfusion, sarco-lemmal integrity and intact metabolic function. These three properties have been shown to be important requirements in order to permit recovery of systolic function after restoration of normal perfusion in dysfunctional myocardium.

Assessment of myocardial viability before revascularization: Can sestamibi accurately predict functiarization . The awareness of the potential of even severe regional and global dyssynergic myocardium to improve its functional state, has resulted in a search for the optimal diagnostic approach for its noninvasive assessment. The identification of myocardial regions with high and low probabil

Assessment of viability in noncontractile myocardium before revascularization and prediction of funcinetic principles has stimulated diagnostic in vivo tissue characterization in humans. While the concept of biological imaging has gained attraction for probing both the central nervous system and neoplastic tissues, current diagnostic benefit from PET is probably best defined in cardiovascular medi
