Abstract

Positron Emission Tomography (PET) is a nuclear-medicine based diagnostic modality that gives many advantages in diagnosing malignancy. PET scanner detects radioactive materials that accumulates in organ after intravenous injection of labelled materials. PET scan illustrates functional blood flow and cellular metabolic processes. PET scan is very useful in staging, restaging, assessment of recurrency, and also evaluation of therapy in non small cell lung cancer. Less benefit could be obtained in assessing small cell lung cancer. PET scans sensitivity and specificity are able to distinguish benign and malignant lesion. Combined CT and PET scan assessment offer more extensive clinical information on tumor staging (T) in non small cell lung cancer. PET scan could assess lymph nodes better than CT scan. Metastasis of non small cell lung cancer could be detected superiorly by PET scan apart from brain metastasis.Keywords: nuclear medicine, PET scan, non small cell lung cancer, staging
