Module Description

Computes the standardized uptake value based on body weight. references gives more details on the algorithm.

Computes the standardized uptake value based on body weight. Takes an input PET image in DICOM and NRRD format (DICOM header must contain Radiopharmaceutical parameters). Produces a CSV file that contains patientID, studyDate, dose, labelID, suvmin, suvmax, suvmean, labelName for each volume of interest. It also displays some of the information as output strings in the GUI, the CSV file is optional in that case. The CSV file is appended to on each execution of the CLI.

Use Cases

This command line module was developed for a special use case in which many different VOIs were specified on the fused structural and PET images; SUV maximum, SUV minimum, SUV mean were computed for each of these labels and the resulting quanitative measures were output to a comma-separated value (csv) file of the user's choosing.

Since various study parameters for the datasets are required for these measurements, a pointer to the DICOM directory is also provided to the computation.

This module does not visualize the functional and structural dataset. Instead, it saves all measurements to the csv file as well as showing the following quantitative measures in Slicer's interface: label name, label value, SUV max, SUV mean, SUV minimum.
