Myocardial perfusion SPECT: Perfusion quantification
Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically. Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...
متن کاملCMR-based quantitative myocardial perfusion: pixel-wise and pound-wise.
p b c uantitative measurement of myocardial perfusion has been a goal of cardiovascular investigators for a number of years. Positron emission tomography (PET) has allowed assessment of myocardial blood flow in absolute value (milliliters per gram per minute) (1) and is accurate at dentifying both flow-limiting epicardial coronary artery isease (CAD) as well as microvascular abnormalities. uali...
متن کاملFully automated pixel-wise myocardial blood flow quantification with first-pass perfusion CMR
Methods Rest and adenosine stress perfusion imaging was performed on 17 normal volunteers. A saturation recovery SSFP dual-sequence technique was used to acquire three myocardial slices and an arterial input function (AIF) image series. A proton-density weighted image was acquired at the beginning of each series. Fully quantitative perfusion pixel maps were generated by an automated processing ...

متن کاملNormal myocardial perfusion values on high-resolution pixel-wise perfusion maps
Background The feasibility and pre-clinical validation of pixel-wise quantification of myocardial perfusion on standard and high-resolution first-pass perfusion CMR images has been recently described. However, the diagnostic criteria for the detection of CAD have not yet been defined and normal values in healthy subject are unknown. Aim of this study was to define normal reference values of str...
