II. Indications

  1. Suspected Ovarian Malignancy (e.g. Adnexal Mass)

III. Criteria: Ultrasound (assign 1 point if 1 characteristic, 2 points if >1 characteristic)

  1. Bilateral lesions
  2. Findings consistent with metastases
  3. Solid areas
  4. Multilocular cyst
  5. Ascites

IV. Criteria: Menopausal Status

  1. Premenopausal: 1 point
  2. Postmenopausal: 3 points

V. Criteria: Serum CA-125 Level

  1. Use actual level in U/ml in calculation

VI. Calculation

  1. RMI = U * M * C
  2. Where U is Ultrasound criteria, M is menopausal status, and C is CA-125 level

VII. Interpretation

  1. RMI >200 is associated with a higher Ovarian Cancer risk
  2. RMI Threshold may vary by ethnicity and race

VIII. Efficacy
