Use the SUV Calculator to calculate a specific uptake value (SUV), given the appropriate entries of injected dose, subject weight, and activity concentration.
Getting There
Access the SUV Calculator by going to Advanced Modules > NucMed > SUV Calculator.
Function
The SUV Calculator requires several values to make its calculations. An activity and volume are used to calculate an activity concentration. The subject weight and injected dose are used in conjunction with the activity concentration to calculate the SUV. Units for these entries are user-selectable.
| Value | Units | Description |
|---|---|---|
| Activity | MBq, kBq, mCi, or μCi |
Amount of isotope as measured in a dosimeter or with the NanoSPECT. |
| Volume | cm3, mm3, ml, μl |
The volume containing the activity. |
| Concentration | kBq/ml, MBq/ml, mCi/ml, kBq/mm3, MBq/mm3 |
The ratio of activity to volume. |
| Patient Weight | g, kg |
The weight of the animal or object of interest. |
| Injected Dose | MBq, kBq, mCi, or μCi |
The amount of isotope successfully injected into the subject. |
| SUV | mg/ml, g/ml, kg/ml, g/l, g/mm3, kg/mm3 |
The specific uptake value (SUV) given the patient weight, activity concentration, and injected dose specified in the other fields. |
