SUV
Calculates the standardized uptake value (SUV) of a PET image. The SUV is a dimensionless, semiquantative measure of tracer uptake, i.e. it is the ratio of actavity in each voxel related to the injected activity. It is calculated as
where \(r\) is the radioactivity concentration measured by the PET scanner, \(a'\) is the decay corrected amount of injected tracer and \(w\) is the patient weight.
Inputs
PET Image
PET image(s). To calculcate SUV (without having to override the metadata and provide numbers manually), some metadata tags pertaining to half-life, patient weight, total administered dose and administration time are mandatory.
Type: Image, List, Required, Single
Outputs
SUV Image
The output SUV parameter map(s).
Type: Image, List
Settings
Override Metadata
Patient Weight Boolean
If set the specified patient weight will be used instead of the weight from metadata.
Half Life Boolean
If set the specified half life will be used instead of the half life from metadata.
Total Dose Boolean
If set the specified dose will be used instead of the dose from metadata.
Administration Date Boolean
If set the administration date will be used instead of the date from metadata.
Administration Time Boolean
If set the administration time will be used instead of the time from metadata.
Override Parameters
Patient Weight [kg] Float
New patient weight in kg.
Half Life [s] Float
New halflife in seconds.
Total Dose [MBq] Float
New total dose in MBq.
Administration Date Text
New administration date, format as yyyymmdd.
