1. Viewing technique
→
PET-MIP (LK?) -> PET volume -> CT
2. Reading criteria
→
visibility in the MIP leading
3. How to deal with equivocal findings
→
include Prä-Test Probability
(Giraud et al.)
in doubt: report positively
(RT-context!)
1. LN station infiltrated by primary
→
report positively
2. Anatomical allocation
→
use atlas!
3. Bulky disease
→
report all affected LN stations
