Radiologic Assessment of Lymph Nodes in Oncologic Patients

Abstract

Status of lymph node metastasis has important implications in deciding treatment of oncologic patients. The appropriate choice of imaging modality is crucial to obtain accurate evaluation of lymph node status. Current imaging methods are mainly divided into two categories, conventional structural imaging and more recently emerging functional imaging. In depth understanding of these imaging tools is essential in making the correct choice for individual patients, and eventually for better diagnosis and treatment.
