Validation of Myocardial Perfusion Imaging

The new cadmium-zinc-telluride (CZT) technology is a powerful tool for cardiac nuclear medicine.

The use of dual isotope imaging is very interesting because this imaging combines the use of thallium-201 with technetium-99m agents permitting optimal image resolution and simultaneous assessment o...

Comparison of Coronary CT Angiography With Conventional Coronary Angiography in Liver and Lung Transplant Candidates

The overall goal of this study is to determine if non-invasive imaging with state of the art CT coronary angiography can be used to screen for coronary artery disease in high risk patients prior to liver and lung transplantation. The current protocol for coronary artery disease assessment at UCSF before liver and lung transplantation involves screening with stress tests and/or coronary angiograms in patients with increased risk of coronary artery disease. Coronary angiogram wil...

Imaging Modalities in Detection of Coronary Artery Disease in End-Stage Renal Disease Patients

This study investigates hypothesizes that the combination of dobutamine stress echocardiography with dobutamine stress echocardiography with real time perfusion myocardial contrast echocardiography and coronary computed tomography is a better modality for detecting coronary artery disease in end-stage renal disease patients than coronary angiography, and in predicting patient outcomes. Demonstrating this would lead to increased use of DSE with RTCE and coronary CT at kidney tr...

Effectiveness Study of Single Photon Emission Computed Tomography (SPECT) Versus Positron Emission Tomography (PET) Myocardial Perfusion Imaging

The purpose of this study is to compare pharmacologic stress myocardial perfusion PET with pharmacologic stress myocardial perfusion SPECT in a near-simultaneous, head-to-head comparison in the same patient. The investigators hypothesize that pharmacologic stress myocardial perfusion PET will prove superior to pharmacologic stress myocardial perfusion SPECT as a first-line diagnostic test for higher-risk patients with known coronary artery disease (CAD) who present with sympto...

Magnetic Resonance Adenosine Perfusion Imaging as Gatekeeper of Invasive Coronary Intervention

Current guidelines for the diagnosis and management of patients with stable coronary artery disease (CAD) strongly support the performance of non-invasive imaging techniques for the detection of myocardial ischemia prior to revascularization procedures. This recommendation originates from the strong evidence base showing the lack of prognostic benefit from percutaneous coronary interventions (PCI) over optimal medical therapy in patients without verification of myocardial ische...

Prognostic Value of Myocardial Perfusion Heterogeneity in Otherwise Normal SPECT Studies

Myocardial perfusion imaging is an efficient tool to assess the risk of major cardiac events for patients with known or suspected coronary artery disease. If the test is normal, or if the abnormalities of perfusion represent less than 10% of the left ventricle myocardium, the patient is considered at low risk and should be managed with optimal medical treatment only. Recently, new gamma cameras using semi-conductor detectors have been developed. Their diagnostic performances h...
