Role of Imaging in the Assessment of Benign and Malignant Lymph Nodes: A Comprehensive Study of Diagnostic, Staging, and Prognostic Implications

Abstract

Lymphadenopathy is a common clinical finding, and differentiating benign from malignant lymph 
nodes is crucial for diagnosis, staging, and treatment planning. Imaging plays a vital role in this 
assessment by providing morphological and functional characteristics that aid in distinguishing 
between benign and malignant lymphadenopathy. Ultrasound (USG), computed tomography 
(CT), magnetic resonance imaging (MRI), and positron emission tomography-computed 
tomography (PET-CT) are commonly employed modalities, each offering unique diagnostic 
advantages.
