"Thyroid Imaging Reporting and Data System (TI-RADS) refers to any of several risk stratification systems for thyroid lesions, usually based on ultrasound features, with a structure modelled off BI-RADS. The following article describes the initial iterations proposed by individual research groups, none of which gained widespread use. Refer to separate articles for the latest systems supported by various professional societies:"

"A TI-RADS was first proposed by Horvath et al. in 2009 1. The system has fair interobserver agreement 4."
"TI-RADS 1: normal thyroid gland"
"TI-RADS 2: benign conditions (0% risk of malignancy)"
"TI-RADS 3: probably benign nodules ("
"TI-RADS 4: suspicious nodules (5-80% malignancy)"
"TI-RADS 4a: undetermined (5-10% malignancy)"
"TI-RADS 4b: suspicious (10-80% malignancy)"

"Thyroid nodules could be classified into one of 10 ultrasound patterns, which had a corresponding TI-RADS category."

"The authors stated that TI-RADS 4 and 5 nodules must be biopsied."
"In 2009, Park et al. proposed a system with five categories, which, like BI-RADS, each carried a management recommendation 2. The risk of malignancy was derived from thyroid ultrasound (TUS) features."
"The above systems were difficult to apply clinically due to their complexity, leading Kwak et al. to propose a simpler TI-RADS in 2011 3. The system is sometimes referred to as TI-RADS Kwak 6."
"The above systems were difficult to apply clinically due to their complexity, leading Kwak et al. to propose a simpler TI-RADS in 2011 3. The system is sometimes referred to as TI-RADS Kwak 6."
"The category definitions were similar to BI-RADS, based on the risk of malignancy depending on the presence of suspicious ultrasound features:"
"TI-RADS 1: negative (0% risk of malignancy)"
"TI-RADS 2: benign (0% malignancy)"
"TI-RADS 3: probably benign (1.7% malignancy)"
"TI-RADS 4a: low suspicion for malignancy (3.3% malignancy)"
"TI-RADS 4b: intermediate suspicion for malignancy (9.2% malignancy)"
"TI-RADS 4c: moderate concern but not classic for malignancy (44.4-72.4% malignancy)"
"TI-RADS 5: highly suggestive of malignancy (>87.5% malignancy)"
"The study included only nodules ≥1 cm in greatest dimension. The authors suggested, as with BI-RADS, that biopsy candidates were those nodules categorised as TI-RADS category 4 or 5, meaning demonstrating at least one suspicious sonographic feature."

"In 2013, Russ et al. published a simplified TI-RADS that was prospectively validated 5. The system is sometimes referred to as TI-RADS French 6."
