Pitfalls

• Broncho-alveolar carcinoma:

limited/no uptake of FDG

• Border tumor and atelectasis:

not validated with pathology

•

Post-obstruction pneumonia:

increased uptake of FDG

• Inflammatory diseases:

increased uptake of FDG

• Heart:

or mediastinal involvement?

• Movement of tumor:

blurring of PET signal  4D PET-CT
