PXMOD Implementation

Acquisition and Data Requirements

Image Data	A static PET data set representing the equilibrium brain activity during C¹⁵O inhalation. If more than one frame has been loaded, the average PET activity is calculated during the pixel-wise calculations.
Blood Data	Blood activity sampled at a peripheral artery after equilibration from beginning until the end of the PET acquisition.

Blood Preprocessing

The only available blood preprocessing option is decay correction.

Model Preprocessing

Just reads numerical data needed for pixel-wise processing in two input fields.

PXMOD rBV (Autorad) Model Pre-Processing

R	Haematokrit Ratio Small/Large Vessels. Mean ratio: 0.85.
D	Density of brain tissue: 1.05 [g/ml].

Map Parameters

PXMOD rBV (Autorad) Model Parameters

rBV

Regional blood volume in [ml/100g]. It is calculated as:
rBV = PET*100/(R*D*integrated_blood)
