RadLex is a controlled terminology for radiology. The purpose of RadLex is to provide a uniform structure for capturing, indexing, and retrieving a variety of radiology information sources. This may facilitate a first step toward structured reporting of radiology reports. The RadLex project – to develop a comprehensive radiology lexicon – is sponsored by the Radiological Society of North America (RSNA), along with the collaboration of the American College of Radiology (ACR) and other subspecialty societies.
