I'd have it taken out too. If you plug his data on an SPN calculator, without the PET result his probability of malignancy is ~97% but even with the PET it is still ~70% (!).
Could someone tell us where to find a SPN calculator? I take it SPN means solitory pulmonary nodule. Is it a freeware application?
I use the one from chest-xray.com: http://www.chestx-ray.com/SPN/SPNProb.html . It is a free application.
(im just a pre-med student, so dont take what i say too seriously)what about the ct scan enhancement??? since the nodule is relatively small a false negative pet might be considered. and yea the spiculated feature and the >25years of tabaco use definitely increase the risk of malignancy! Any pfts information??? if it was my brother
i would send him to surgery right away!
Yes ... based on size .. I would biopsy ... even with a negative PET ... BAC can be negative on PET so.. it would be prudent ...
