Myocardial blood flow assessment with 82rubidium-PET imaging in patients with left bundle branch block
OBJECTIVES Perfusion abnormalities are frequently seen in Single Photon Emission Computed Tomography (SPECT) when a left bundle branch block is present. A few studies have shown decreased coronary flow reserve in the left anterior descending territory, regardless of the presence of coronary artery disease. OBJECTIVE We sought to investigate rubidium-82 (82Rb) positron emission tomography imag...
متن کاملImprovement of algorithm for quantification of regional myocardial blood flow using 15O-water with PET.
UNLABELLED (15)O-Water and dynamic PET allow noninvasive quantification of myocardial blood flow (MBF). However, complicated image analyzing procedures are required, which may limit the practicality of this approach. We have designed a new practical algorithm, which allows stable, rapid, and automated quantification of regional MBF (rMBF) using (15)O-water PET. We designed an algorithm for sett...
متن کاملA Nonlinear Variational Method for Improved Quantification of Myocardial Blood Flow Using Dynamic H2O PET
H2O as a PET-tracer offers the opportunity to examine perfusion of blood into tissue non-invasively (cf. [1]). It features a short radioactive half-life (≈ 2 min.) and therefore adds a smaller radiation exposure to the patient in comparison to other tracers. The disadvantages arising from the short radioactive half-life are noisy, low-resolution reconstructions. Previous algorithms first recons...
متن کاملQuantification of Myocardial Blood Flow Using Microbubbles
Ultrasound can cause microbubble destruction. We hypothesized that ultrasound induced microbubble destruction can be used to quantify myocardial blood flow. in viva experiments were performed where microbubbles were delivered as a constant infusion, and ultrasound examination was performed using different pulsing intervals from which microbubble velocity and microvascular cross-sectional area w...
متن کاملPrecision and accuracy of clinical quantification of myocardial blood flow by dynamic PET: A technical perspective.
A number of exciting advances in PET/CT technology and improvements in methodology have recently converged to enhance the feasibility of routine clinical quantification of myocardial blood flow and flow reserve. Recent promising clinical results are pointing toward an important role for myocardial blood flow in the care of patients. Absolute blood flow quantification can be a powerful clinical ...
