TI-RADS Calculator

The American College of Radiology (ACR) TI-RADS framework assigns points to five distinct ultrasound feature categories. The final score is computed as the sum of points from each category: tirads_score = composition + echogenicity + tirads_shape + tirads_margin + foci1 + foci2 + foci3. Each feature reflects specific physical characteristics of the nodule, where higher point values correlate with a greater likelihood of malignancy and guide whether monitoring or biopsy is warranted.

Consider a patient with a thyroid nodule showing the following ultrasound characteristics: mixed cystic and solid composition (2 points), hypoechoic echogenicity (2 points), wider-than-tall shape (0 points), smooth margins (0 points), and the presence of punctate echogenic foci (3 points). Adding these values together gives our calculation: 2 + 2 + 0 + 0 + 3 = 7 total points. Referring to the ACR TI-RADS risk matrix, a score of 7 categorizes this nodule as TR5, indicating a high risk of malignancy and suggesting that a biopsy should be performed if the nodule size meets specific threshold criteria.

Always rely on a professional radiology report performed by a certified ultrasound technician or radiologist when inputting data into the calculator. Avoid attempting to self-diagnose based on home scans, as subtle acoustic features require specialized clinical training to identify accurately. Finally, use the TI-RADS score in close consultation with your endocrinologist or primary care physician to determine the safest follow-up or biopsy schedule.
