The clinical value of myocardial blood flow measurement.
PET provides robust and reproducible measurements of regional myocardial blood flow in milliliters per minute per gram of tissue, providing unique pathophysiologic and diagnostic information on the function of the coronary macro- and microcirculation. There is compelling evidence to suggest that in many instances abnormalities of global myocardial perfusion are demonstrated in individuals with ...
متن کاملMeasurement of myocardial blood flow.
This paper represents a review of the recent literature on techniques to measure myocardial blood flow in man. A short discussion on flow meters in followed by a more detailed discussion of the radionuclide techniques used to measure myocardial blood flow. The radionuclide techniques are discussed in two groups: (1) qualitative measurement of blood flow using static images; and (2) quantitative...
متن کاملMeasurement of Myocardial Blood Flow
A"CLOSED" method for the accurate measurement of myocardial blood flow is still to be achieved. In 1956, Henly et al. described an indicator-dilution technique for assessing myocardial blood flow. This approach led us to construct a suitable model for simulating a systemic-coronary circuit. Observations with this system suggested that an indicator-dilution technique might be applicable to measu...
متن کاملMeasurement of regional myocardial blood flow with multiple colored microspheres.
BACKGROUND The use of radioactive microspheres (RM) for the measurement of regional myocardial blood flow (RMBF) is limited and inaccessible to many investigators due to radiation safety concerns and radioactive waste disposal problems. Therefore, a new method for the measurement of RMBF using colored microspheres (CM) was developed. METHODS AND RESULTS Polystyrene spheres (diameter, 15 +/- 0...
متن کاملMeasurement of myocardial blood flow by ultrafast computed tomography.
Myocardial blood flow was analyzed by radioisotope-labeled microspheres and ultrafast computed tomography (CT) in 16 closed-chest, anesthetized dogs. The first set of 10 dogs had CT and microsphere measurements before and after chromonar-induced increases in myocardial blood flow. A second set of six dogs had flows measured at control and during temporary reductions in regional flow produced by...
