Evaluation of the Novel Myocardial Perfusion Positron-Emission Tomography Tracer
Background—Positron-emission tomography (PET) tracers for myocardial perfusion are commonly labeled with short-lived isotopes that limit their widespread clinical use. F-BMS-747158-02 (F-BMS) is a novel pyridaben derivative that was evaluated for assessment of myocardial perfusion by comparison with N-ammonia (NH3) and with radioactive microspheres in a pig model. Methods and Results—Fourteen p...
متن کاملPositron emission tomography myocardial perfusion and glucose metabolism imaging.
Cardiac positron emission tomography (PET) imaging is a well-validated, reimbursable means to assess myocardial perfusion, left ventricular (LV) function, and viability. Presently, there is a proliferation of PET and PET/computed tomography (CT) instrumentation as well as an increase in educational programs that specifically address PET and PET/CT imaging. Technologists performing PET scans as ...
متن کاملMyocardial perfusion scintigraphy using rubidium-82 positron emission tomography.
INTRODUCTION Myocardial perfusion scintigraphy (MPS) is an established non-invasive technique for the diagnosis and management of patients with suspected or known coronary artery disease. Because of the wealth of prognostic data, MPS single photon emission computed tomography (SPECT) is the most commonly used functional test to detect inducible ischaemia. However, the increasing availability of...
متن کاملPrognostic Value of Stress Myocardial Perfusion Positron Emission Tomography
Results Risk-adjusted hazard of cardiac death increased with each 10% myocardium abnormal with mildly, moderately, or severely abnormal stress PET (hazard ratio [HR]: 2.3 [95% CI: 1.4 to 3.8; p 0.001], HR: 4.2 [95% CI: 2.3 to 7.5; p 0.001], and HR: 4.9 [95% CI: 2.5 to 9.6; p 0.0001], respectively [normal MPI: referent]). Addition of percent myocardium ischemic and percent myocardium scarred to ...
متن کاملQuantification of Absolute Myocardial Perfusion With Dynamic Positron Emission Tomography
Positron emission tomography (PET) was applied to the measurement of myocardial perfusion using the perfusion tracer 13N-labeled ammonia. 13N ammonia was delivered intravenously to 13 healthy volunteers both at rest and during supine bicycle exercise. Dynamic PET imaging was obtained in three cross-sectional planes for 10 minutes commencing with each injection. The left ventricle was divided in...
