Fig 3. Example of Positron-Emission-Tomography image reconstruction using the pmod cardiac PET modelling tool (pmod version 3.8, PMOD technologies LLC, Zurich, Switzerland) and quantification of 18F-DOPA uptake in the left ventricular wall.
A semiquantitative uptake analysis using the upper limit of the standardized uptake value (SUVmax-N) and the mean SUV (SUVmean-N) at the sites of physiologic uptake was performed using a planar circular region of interest of 1 cm diameter, automatically generated by the computer. Left ventricular segments in the horizontal long axis were defined as follows: a = basal septal, b = midventricular septal, c = apical septal, d = apical lateral, e = midventricular lateral, f = basal lateral. A. Cardiac long axis image of a 41 year old male patient. B. Cardiac long axis image of a 66 year old male patient. C. Cardiac long axis image of a 39 year old female patient. D. Cardiac long axis image of a 72 year old female patient. Similar thresholds were applied for all images.
