The scoring is broadly similar to the [[BI-RADS]] and consists of six possible categorizations:<ref name=pmid19276237>{{Cite journal  | last1 = Horvath | first1 = E. | last2 = Majlis | first2 = S. | last3 = Rossi | first3 = R. | last4 = Franco | first4 = C. | last5 = Niedmann | first5 = JP. | last6 = Castro | first6 = A. | last7 = Dominguez | first7 = M. | title = An ultrasonogram reporting system for thyroid nodules stratifying cancer risk for clinical management. | journal = J Clin Endocrinol Metab | volume = 94 | issue = 5 | pages = 1748-51 | month = May | year = 2009 | doi = 10.1210/jc.2008-1724 | PMID = 19276237 }}</ref>

=="Original" TIRADS==
The original TIRADS is broadly similar to [[BI-RADS]] and consists of six possible categorizations:<ref name=pmid19276237>{{Cite journal  | last1 = Horvath | first1 = E. | last2 = Majlis | first2 = S. | last3 = Rossi | first3 = R. | last4 = Franco | first4 = C. | last5 = Niedmann | first5 = JP. | last6 = Castro | first6 = A. | last7 = Dominguez | first7 = M. | title = An ultrasonogram reporting system for thyroid nodules stratifying cancer risk for clinical management. | journal = J Clin Endocrinol Metab | volume = 94 | issue = 5 | pages = 1748-51 | month = May | year = 2009 | doi = 10.1210/jc.2008-1724 | PMID = 19276237 }}</ref>
