I’m trying to compute SUV values for my FET-PET images, however it throws the following error:
```auto
Geometric issues were found with 1 of the series. Please use caution.

This issue seemed similar to [Unnamed Series as a Scalar Volume - #4 by lassoan](https://discourse.slicer.org/t/unnamed-series-as-a-scalar-volume/22085/4)
Here, the advice was to check that certain values in the metadata we’re not ruined by anonimization.
However, I can’t find the following attributes in my metadata: injectedDose, patientWeight, , injectionTime, radionuclideHalfLife. I was wondering what I’m doing wrong here?
I obtain the metadata by right-clicking on the patient file → “View metadata”. The metadata looks as follows:

This is just a warning. Details about it are found in the application log. It is probably not the reason for the SUV computation to fail.
Check out the application log if you find more information about why the SUV calculation fails.
