PET Imaging – Realizing a Star Trek Tricorder

PET_Blog

PET scanning is utilized in skin cancer staging by detecting regional lymph node metastases as well as distant organ metastases. Its specificity is superior to CT and MR for N-staging, particularly with melanoma. It can be the superior modality for primary tumor staging as well. PET scan imaging is based on the increased metabolic activity…
