Tool for automated measurement of liver uptake in SUV normalized whole-body FDG-18 PET scans. The tool automatically identifies a spherical region inside of the liver and measures mean, standard deviation and median uptake in the identified region. In the majority of cases the user only needs to specify the input PET scan. However, to be able to deal with unusual cases where standard parameters regarding the liver's location or appearance are not applicable, the tool allows the user to provide additional guidance to the algorithm.

Module Description

Tool for automated measurement of liver uptake in SUV normalized whole-body FDG-18 PET scans. The tool automatically identifies a spherical region inside of the liver and measures mean, standard deviation and median uptake in the identified region. In the majority of cases the user only needs to specify the input PET scan. However, to be able to deal with unusual cases where standard parameters regarding the liver's location or appearance are not applicable, the tool allows the user to provide additional guidance to the algorithm.

Tutorial - Fully Automated Liver Uptake Measurement

Step 1) Load SUV normalized whole-body FDG-18 PET scan using the DICOM PET SUV Plugin which is part of the UIowa QIN PET DICOM Extension.

Step 2) Go to the “PET Liver Uptake Measurement” module.

Step 3) Select the loaded PET scan as "Input Volume".

Step 4) (Optional) Under "Output Volume" select "Create new LabelMapVolume". If an output volume is selected, the tool will visualize the identified liver reference region which is utilized for uptake measurement.

Step 5) Click "Apply".

Step 6) In section "Measurements" read the measured "Mean", "Standard Deviation" and "Median" SUV values of the identified liver reference region.
