What Is TI-RADS?
TI-RADS helps turn Composition and Echogenicity into a clearer answer for personal tracking, wellness planning, education, and professional review.
Use the result as a practical estimate, then compare it with the real limit, target, benchmark, or rule that applies to your situation.
TI-RADS Formula and Calculation Method
TI-RADS is worked out from Composition, Echogenicity, Foci1, and Foci2. Start by making sure those values describe the same item, period, unit system, or situation; then use foci3 as the main number to review.
The main values to check are Composition, Echogenicity, Foci1, and Foci2. Those values should describe the same situation before you rely on the TI-RADS result.
Check units, dates, percentages, and boundaries before relying on the answer. Most errors come from entering values that look reasonable but do not describe the same situation.
How to Use the TI-RADS Calculator
Start with the input that is easiest to verify, then review the unit, date, rate, or option beside each remaining field.
If one value is uncertain, try a low and high version. That gives you a better feel for how sensitive the TI-RADS result is.
Step-by-step
- Enter Composition using the unit shown on the form.
- Add Echogenicity with the same time period, unit system, or scenario in mind.
- Look at Foci3, Foci1, Tirads Margin before making a decision.
- Adjust one value at a time if you want to compare different TI-RADS cases.
Input guide
- Composition lets you choose the scenario that matches your case, such as Cystic/Spongiform, Mixed cystic and solid, Solid.
- Echogenicity lets you choose the scenario that matches your case, such as Anechoic, Hyperechoic or isoechoic, Hypoechoic, Very hypoechoic.
- Foci1 lets you choose the scenario that matches your case, such as Macrocalcifications, .
- Foci2 lets you choose the scenario that matches your case, such as Peripheral (rim) calcifications, .
- Margin lets you choose the scenario that matches your case, such as Smooth/Ill defined, Lobulated or irregular, Extra-thyroidal extension.
- Score is the number you enter for the calculation.
- Shape lets you choose the scenario that matches your case, such as Wider-than-tall, Taller-than-wide.
- Foci3 lets you choose the scenario that matches your case, such as Punctate echogenic foci, .
Example Calculation
For example, enter Composition = 0, Echogenicity = 0, Foci1 = 1, Foci2 = 2. The result is foci3 of Calculated. Replace the example numbers with your own values when you are ready to check your case.
After the example, replace the sample numbers with your own values. If the result feels too high or too low, check the units and change one input at a time.
- Choose cystic/spongiform in Composition when it best matches your situation.
- Choose anechoic in Echogenicity when it best matches your situation.
- Choose macrocalcifications in Foci1 when it best matches your situation.
- Choose peripheral (rim) calcifications in Foci2 when it best matches your situation.
- Choose smooth/ill defined in Margin when it best matches your situation.
Understanding Your Results
foci3 is the number to look at first, but it should not be read on its own. Whether the answer is high, low, good, bad, efficient, or expensive depends on the units, limits, and assumptions behind the TI-RADS calculation.
Useful result lines include Foci3, Foci1, Tirads Margin, Tirads Shape, Composition. Read them together instead of relying only on the first number.
If the answer is much higher or lower than expected, recheck the measurement, units, timing, and whether the value should be interpreted with age, sex, symptoms, medications, or medical history.
Why This Metric Matters
TI-RADS matters because it helps with personal tracking, wellness planning, education, and professional review. A clear number makes it easier to compare options and explain why one choice looks better than another.
Use it when you want a fast first-pass estimate before doing a manual review. It can also help when one assumption change could materially affect the answer. Treat the result as a practical estimate, not as a promise that every real-world detail has been captured.

- Advisors discussing retirement income scenarios
- Employees comparing savings goals and expected income replacement
Common Mistakes When Calculating TI-RADS
- Using outdated or estimated values for Composition.
- Pairing Echogenicity with a measurement from a different time, person, or unit system.
- Ignoring age, sex, symptoms, medications, training status, pregnancy, or health history when those details matter.
- Comparing the result with a reference range that does not apply to the person or situation.
- Using the calculator result as medical advice instead of educational context.
How TI-RADS Inputs Work Together
Most TI-RADS results are not controlled by one field alone. The answer changes when Composition, Echogenicity, Foci1, and Foci2 change together.
If the result surprises you, check whether the inputs belong together before assuming the answer is wrong. A formula can be mathematically correct and still be unhelpful if the values describe different periods, units, or groups.
- Composition works with Echogenicity; changing either one can move foci3.
- Echogenicity works with Foci1; changing either one can move foci3.
- Foci1 works with Foci2; changing either one can move foci3.
- Foci2 works with Margin; changing either one can move foci3.
- Margin works with Score; changing either one can move foci3.
TI-RADS Limitations
The TI-RADS result is only as good as the values you enter. Even a correct formula can mislead you if the inputs are outdated, rounded too much, or measured under different conditions.
If the result could influence medical, nutrition, pregnancy, or treatment decisions, use it as an educational estimate and verify it with a qualified clinician or specialist.
If you plan to share the answer, keep the inputs with it. That makes the TI-RADS calculation easier to check, repeat, or update later.
