Communication in radiology: evaluation of terminology and TNM descriptor use at a cancer center

Abstract Objective: The purpose of our study was to evaluate the transmission of information from radiologists to physicians, focusing on the level of certainty and the use of imaging descriptors from the tumor–node–metastasis (TNM) staging system. Materials and Methods Radiologists (n = 56) and referring physicians (n = 50) participated in this questionnaire-based, single-center study, conducted between March 20, 2020, and January 21, 2021. Participants were presented with terms commonly used by the radiologists at the institution and were asked to order them hierarchically in terms of the level of certainty they communicate regarding a diagnosis, using a scale ranging from 1 (most contrary to) to 10 (most favoring). They then assessed TNM system descriptors and their interpretation. Student’s t-tests and the kappa statistic were used in order to compare the rankings of the terms of certainty. Items related to T and N staging were analyzed by Fisher’s exact test. The confdence level was set to 97% (p
