ACR TI-RADS Webinars

• What is the follow-up for TR1 and TR2 nodules? 5:17
• What is the management for TR3, TR4, or TR5 nodules that are below the size threshold for follow-up? 5:17
• What is the rationale behind ACR TI-RADS? 6:20
• Does ACR TI-RADS apply to symptomatic nodules? Do risk factors come into play? 7:33
• How do I report it? 12:45
• In a mixed cystic and solid nodule, does margin apply to the entire nodule or just the solid component? Does color Doppler help? 13:45
• Should a nodule’s suspicion level be reported? 17:10
• Because Punctate Echogenic Foci (PEF) are awarded three points, what can be done to avoid overcalling them? How should linear echogenic foci be reported? 19:10
• If there are more than 4 nodules, should the sonographers take images of all nodules? If not, how do they determine which ones to image? Are there exceptions to formally reporting no more than 4 nodules? 23:08
• Should ACR TI-RADS be used in pediatric patients? 25:30
• How do we distinguish spongiform nodules from mixed cystic and solid nodules, or solid nodules with minimal cystic components? 26:15
• What are the exceptions to ACR TI-RADS? 30:01
• How should we determine echogenicity, especially distinguishing iso from hypoechoic nodules? 37:04
• If a nodule is truly round (i.e., not wider-than-tall or taller-than-wide), how should it be scored? 40:20
• Is there a size below which a nodule cannot be accurately characterized? 42:08
• What should be done if a nodule changes and receives a follow-up score that is higher than the scores of previously-followed nodules? 43:15
• How should we handle patients who had US that were done prior to ACR TI-RADS and may have had more than four nodules followed? 44:00
• In determining management, should the nodule’s largest measurement or an average of all three measurements be used? 45:19
• What should we report for previously-biopsied nodules? 45:32
• If there are two nodules with the same TR level, and one meets size criteria for FNA but the other does not, what recommendations should we provide? 46:25
• Is ACR TI-RADS an accepted standard? 47:29
• Should reports include a disclaimer stating that some cancers may be missed? 48:28
• Why not give an overall ACR TI-RADS score to the thyroid, rather than individual nodules? 48:50
• Where can the structured report be accessed? 49:37
• Comments on adoption of ACR TI-RADS 52:58
• How would you report a thyroid nodule that is known to be malignant (e.g. similar to BIRADS 6)? 54:45
• Is there a specific definition for multinodular goiter in TI-RADS? Would you assign a TI-RADS category to nodules in MNG? 56:04
• Additional Resources 58:26
