title: [The Thyroid Imaging Reporting and Data System (TIRADS) for ultrasound of the thyroid].
abstract: OBJECTIVE
  To develop a standardized system for analyzing and reporting thyroid ultrasound, or Thyroid Imaging Reporting and Data System (TIRADS), in order to improve the management of patients with thyroid nodules.
  
  
  METHODS
  An atlas of imaging features, a standardized vocabulary, a report template and TIRADS categories 0 to 6 were defined, based on the BI-RADS system used for mammography. The diagnostic efficacy of the system was tested by a retrospective review of 500 nodules (159 cancers and 341 benign nodules) and comparing US imaging features to histological findings.
  
  
  RESULTS
  Five signs allow accurate detection of 90% of thyroid cancers. The score of a nodule can be easily defined by using an organigram. Sensitivity, specificity and odds-ratio of the score were respectively 95%, 68% and 40.
  
  
  CONCLUSIONS
  TIRADS is a quality assurance tool for thyroid ultrasound. It contains an image atlas, a standardized report and categories to evaluate thyroid nodules to easily assess the risk of individual nodules being cancers and facilitate patient management.
