How this service works
Timmerman 2008 simple ultrasound rules. Caller assigns five M-rules (irregular solid tumor; ascites; ≥4 papillary structures; irregular multilocular-solid ≥100 mm; very high color Doppler) and five B-rules (unilocular cyst; solid component <7 mm; acoustic shadows; smooth multilocular <100 mm; no Doppler flow). Malignant if any M and no B; benign if any B and no M; otherwise inconclusive. magent does not read ultrasound. Not an ovarian-cancer diagnosis. Not RMI. Not Swede. Not SRRisk.
Output
Returns a classification of the adnexal mass as malignant (any M-rule true and no B-rule true), benign (any B-rule true and no M-rule true), or inconclusive (neither condition met, or both M and B rules are triggered), based strictly on the five M-rules and five B-rules supplied by the caller.
Example use cases
Benign ovarian cyst pre-op triage
“I have a patient with a smooth multilocular cyst under 100mm, acoustic shadows present, no solid component, and no Doppler flow — run the IOTA simple rules and tell me if this looks benign, malignant, or inconclusive before we decide on surgery.”
M-rule triggered malignancy flag
“The ultrasound shows ascites and an irregular solid tumor with very high color Doppler — no benign features at all. Can you apply the Timmerman 2008 IOTA simple rules and classify this adnexal mass?”
Inconclusive mixed-feature mass workup
“My patient has a unilocular cyst but also at least four papillary structures — there are both B-rule and M-rule features present. Run the IOTA simple ultrasound rules so I can document whether the result is inconclusive before ordering further imaging.”

Endpoint
GEThttps://api.magentlab.com/api/calc/iotaWhen to prefer
Choose this endpoint when you need a fast, standardized application of the validated Timmerman 2008 IOTA simple ultrasound rules to caller-assigned ovarian mass features. Prefer it over RMI, Swede score, or SRRisk endpoints when the clinical context specifically calls for the five M-rule / five B-rule binary classification framework. Not appropriate when you need image reading, Doppler measurement, or a continuous malignancy risk score.
Side effects
- Missing required boolean parameter returns a 400-level error
- All flags set to false returns inconclusive (no rules triggered)
- Conflicting M and B rules both true returns inconclusive — caller must verify ultrasound feature assignment
- Endpoint does not interpret ultrasound images; incorrect caller-assigned flags produce incorrect classifications
