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.
