Interesting data on PET/CT in GCA from Dr Sammel from Sydney incl some pickup of cranial GCA. Not replacing TABx totally but ?similar to MRI/USS with the plus of picking up infx/Ca, with same radiation as full CT. Aussies doing well with PET/CT @drceowen! #ACR18 ABSTL15 @RheumNow https://t.co/omhLbS1xbN
