Diffusion-Weighted MRI for Breast Cancer Screening in Women With a Personal History of Breast Cancer

May 26, 2024 updated by: Woo Kyung Moon, Seoul National University Hospital

Comparison of Diffusion-Weighted MRI and Mammography Alone or Combined Mammography and Ultrasonography for Screening Women With a Personal History of Breast Cancer (DIMRISC-2 Study)

Women with personal history of breast cancer (PHBC) are at risk of developing second breast cancers in the conserved and contralateral breast. Because early detection of second breast cancers at the asymptomatic phase can improve relative survival by 17-28%, guidelines recommend annual mammography screening in women with PHBC. However, lower sensitivity and higher interval cancer rates are observed in women with a PHBC compared with women without, especially in women 50 years or younger and those with dense breasts. In a multicenter comparison study of 754 women, MRI screening detected 3.8 additional cancers and ultrasonography detected 2.4 additional cancers, and increased sensitivity over mammography alone. However, the use of breast MRI is limited not only by high costs and long examination time but also by high false-positive findings. In addition, the use of intravenous gadolinium-based contrast agent is contraindicated in women with renal impairment or contrast material allergy contrast. Supplemental ultrasonography in patients with PHBC reports lower sensitivity with high interval cancer rate. Thus, there is a need to develop a more safe, accurate, and cost-effective supplemental imaging modality for screening in women with PHBC. Diffusion-weighted (DW) MRI is an unenhanced fast, functional modality that measures the movement of water molecules to create tissue contrast. Breast malignancies exhibit hindered diffusion and appear hyperintense on DW MRI with low apparent diffusion coefficient (ADC) compared to normal surrounding tissue. Multiple studies have shown that the use of DW MRI can significantly reduce the false positives and unnecessary benign biopsy of breast MRI. Several studies have shown that DW MRI has a potential to detect mammography occult breast cancers with less false positives compared to ultrasonography. These observations have led to the consideration of utilizing DW MRI to screen women with PHBC. In Diffusion-weighted MRI for Breast Cancer Screening (DIMRISC-2) study, we hypothesized that the screening performance of high-resolution DW MRI at 3.0 T should be superior to mammography alone or combined mammography and ultrasonography in women with PHBC. In our institution, alternating conventional imaging and DW MRI screening is offered for patients who have undergone breast surgery and at increased risk of an interval second breast cancer.

Detailed Description

  • Primary objective: to compare the screening performance of DW MRI versus mammography alone or combined mammography and ultrasonography in women with PHBC.
  • Secondary objective: to compare the tumor and patient characteristics detected by DW MRI and combined mammography and ultrasonography in women with PHBC.
  • This is a prospective, single center, observational cohort study.
  • A total of 1694 women will be enrolled in this study.
  • Two latest 3.0 T MRI scanners with dedicated 16- or 18-channel bilateral breast coil are used for DW MRI. For DW MRI screening, the high-resolution echo-planar imaging sequence is designed to have an in-plane resolution of 1.3 x 1.3 mm and a slice thickness of 3 mm. Three b values of 0, 800, and 1200 sec/mm2 are used and ADC maps are generated based on the b=0 and 800 sec/mm2 DW MRI data. The DW MRI images are reconstructed into single summation images with maximum-intensity projections (MIPs) in the sagittal and axial planes. In addition, T1-weighted imaging sequence is also obtained with in-plane resolution of 1.0 x 1.0 mm and a slice thickness of 1 mm.
  • All patients with PHBC undergo digital two-dimensional mammography and physician-performed whole-breast ultrasonography on the same day. DW MRI and conventional imaging (mammography and ultrasonography) are alternatively scheduled at 6-month intervals and the order has been randomized.
  • Mammography alone, combined mammography and ultrasonography, and DW MRI will be interpreted independently according to the Breast Imaging Reporting and Data System (BI-RADS) and likelihood of malignancy (Score range, 0%-100%) by trained radiologists. DW MRI interpretation guidelines to be used in this study are based on both qualitative and quantitative assessments. Radiologists are required to successfully complete a training case series of 100 DW MR studies prior to interpreting the DW MRI.
  • A negative examination result is defined as a final assessment BI-RADS category of 1, 2, 3 and a positive examination result is defined as a final assessment BI-RADS category of 4 or 5.
  • Biopsies of DW MRI-detected lesions are performed under ultrasonography guidance whenever possible or with MR guidance if there is no correlative ultrasonography finding. Pathology of core or surgical biopsy and 1 year follow up is the reference standard.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
