Lessons Learned from a Negative Biopsy: Impact of Positron Emission Tomography/CT on Targeted Biopsy for Lung Cancer

초록

We introduce two cases in which positron emission tomography (PET)/CT delineated viable malignant tissue from nonmalignant areas and guided us to successful biopsies when conventional CT failed to do so. According to our experience, PET/CT appears to be helpful in deciding the adequate site for biopsy in patients with lung cancer, owing to its capability to delineate malignant from nonmalignant areas, and also to reflect the areas with the most aggressive behaviors, especially in the era of the personalized cancer therapy.
