Node-RADS is a new imaging assessment system that systematically classifies the degree of suspicion of lymph node involvement based on established imaging findings. It improves communication with referring physicians and promotes consistency in reporting for primary staging and response assessment.
Node-RADS addresses the lack of consensus in the radiologic assessment of lymph node involvement by cancer and meets the increasing demand for structured reporting on the likelihood of disease involvement. Node Reporting and Data System 1.0 (Node-RADS) systematically classifies the degree of suspicion of lymph node involvement based on the synthesis of established imaging findings. Straightforward definitions of imaging findings for two proposed scoring categories size and configuration are combined into assessment categories between 1 (very low likelihood) and 5 (very high likelihood). This scoring system is suitable for assessing likely involvement of lymph nodes on CT and MRI scans. It can be applied at any anatomical site, and to regional and non-regional lymph nodes in relation to a primary tumor location. Node-RADS will improve communication with referring physicians and promote the consistency of reporting for primary staging and in response assessment settings.
