Quantitative imaging of coronary blood flow

Positron emission tomography (PET) is a nuclear medicine imaging modality based on the administration of a positron-emitting radiotracer, the imaging of the distribution and kinetics of the tracer, and the interpretation of the physiological events and their meaning with respect to health and disease. PET imaging was introduced in the 1970s and numerous advances in radiotracers and detection sy...

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 ...
