Contrast-Enhanced MRI in Women With Ductal Breast Carcinoma in Situ and in Healthy Volunteers

OBJECTIVES:

- To compare ductal carcinoma in situ (DCIS)-optimized MRI with standard clinical MRI, in
terms of conspicuity of DCIS lesion, agreement of disease extent with biopsy, and
overall image quality (i.e., artifact level, uniformity of fat suppression, contrast to
noise ratio and signal to noise ratio), in women with DCIS of the breast.

- To compare two DCIS-optimized MRIs for variability in enhancement levels for DCIS.

- To examine the effect of the menstrual cycle on the variability of background
enhancement levels in healthy volunteers.

OUTLINE: This is a multicenter study. Patients are randomized to 1 of 2 arms.

- Arm I: Patients undergo standard clinical contrast-enhanced MRI over approximately
30-45 minutes. No more than 3 days later, patients undergo ductal carcinoma in situ
(DCIS)-optimized contrast-enhanced MRI.

- Arm II: Patients undergo DCIS-optimized contrast-enhanced MRI over approximately 30-45
minutes. No more than 3 days later, patients undergo a second DCIS-optimized
contrast-enhanced MRI.

Healthy volunteers undergo DCIS-optimized contrast-enhanced MRI as in arm II.

DISEASE CHARACTERISTICS:

- Has undergone mammography within the past 60 days

- Healthy volunteer

- No prior breast disease

PATIENT CHARACTERISTICS:

- Not pregnant or nursing (or stopped nursing within the past 3 months)

- Negative pregnancy test

- No contraindication to MRI (e.g., implanted pacemaker, implanted ferromagnetic
device, ferromagnetic aneurysm clip, severe claustrophobia, ocular metal fragments,
or shrapnel injury)

PRIOR CONCURRENT THERAPY:

- More than 2 years since prior surgery to the ipsilateral breast (patient)

- No prior radiotherapy to the ipsilateral breast (patient)

- No prior cytotoxic regimens (patient)
