In myocardial perfusion scintigraphy, the results of this evalution now confront the practitioner of nuclear medicine with methodologic options. Most nuclear cardiologic studies are performed using thallium-201, Tc-99m sestamibi and...
Non-invasive evaluation of cardiac function by nuclear medicine technologies are one of the major contribution of nuclear medicine. Gated cardiac blood pool scan was once a novel and robust technique...
Various stem cells or progenitor cells are being used to treat cardiovascular disease. In ischemic heart disease, stem cell therapy is expected to regenerate damaged myocardium. To evaluate effects of...
Ever since it was first introduced as a method of scintigraphically measuring regional myocardial perfusion, myocardial perfusion study has been widely used in patients diagnosed or suspected with coronary artery...
Pharmacologic stress testing for myocardial perfusion imaging is a widely used noninvasive method for the evaluation of known or suspected coronary artery disease. The use of exercise for cardiac stress...
Myocardial perfusion and function can be quantified using SPECT and PET. There was controversy over the usefulness of the correction techniques for physical artifacts, such as photon attenuation and scatter,...
Cardiac PET emerged as a powerful tool that allowed in vivo quantification of physiologic processes including myocardial perfusion and metabolism, as well as neuronal and receptor function for more than...
Positron emission tomography (PET) serves as a gold standard for noninvasive in vivo measurement of myocardial blood flow (MBF) and coronary flow reserve (CFR). CFR can be defined as the...
Hypoxia (decreased tissue oxygen tension) is a component of many diseases such as tumors, cerebrovascular diseases and ischemic heart diseases. Although hypoxia can be secondary to a low inspired pO2...
The potential for recovery of left ventricular dysfunction after myocardial revascularization represents a practical clinical definition for myocardial viability. The evaluation of viable myocardium in patients with severe global left...
Electrocardiogram-gated single photon emission computed tomography (SPECT) provides valuable information in the assessment of both myocardial perfusion and ventricular function. Tl-201 is a suboptimal isotope for gating. Tl-201 images are...
As the indication of percutaneous coronary intervention (PCI) has expanded to the more difficult and complicated cases, frequent restenosis is still expected after PCI. According to AHA/ACC guideline of the...
Coronary artery disease (CAD) has been increasing during the last decade and is the one of major causes of death. The management of patients with coronary artery disease has evolved...
