Quantitative blood flow velocity imaGinG
Laser speckle flowmetry suffers from a debated quantitative relationship with blood flow, velocity or tissue perfusion and a lack of calibration of the inverse relationship 1/τc = αV between decorrelation time (τc) and flow velocity (V). Using a modified microcirculation imager, we experimentally investigate on the influence of the optical properties of scatterers on α in vitro and in vivo. We ...

متن کاملQuantitative myocardial blood flow imaging using PET/CT
Several different tracers have been used for visualizing and quantifying MBF [1-4, 13, 16-18], of which N-ammonia, Rb and O-water are the most widely used (Table 1). Their short half-lives of only several minutes enable MBF to be studied under normal resting and pharmacologically induced stress conditions in the same scanning session (Figures 1-4) in contrast to, for example, F–labeled tracers ...
