May 19, 2026 updated by: Yunnan Cancer Hospital

Performance of Diffusion-weighted Imaging-based Virtual MR Elastography (vMRE) for Diagnosing Breast Cancer: A Prospective Study

This study aims to prospectively collect breast MRE and vMRE image data, clinical data, and pathological data from female patients due to breast lesions indicated by mammography or ultrasound with BI-RADS category 4 or above. It evaluates the consistency of MRE and vMRE in measuring breast lesions and compares the diagnostic performance of the two methods in distinguishing between benign and malignant breast conditions, with the goal of determining whether vMRE has the potential to replace or supplement MRE. Furthermore, it explores and compares the correlation and diagnostic efficacy of sADC and virtual shear modulus calculated at different b-values with the true shear modulus, aiming to identify and optimize the optimal imaging protocol suitable for breast imaging. It also investigates the correlation between quantitative parameters of vMRE and MRE and pathological results such as patient pathological grading and molecular typing, providing imaging evidence for individualized precision assessment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Aged 18 years or older
  • Female patients with breast lesions BI-RADS category 4 and above on mammography or ultrasound
  • Breast MRE and vMRE examinations should be performed within 2 weeks prior to needle biopsy or surgery
  • Obtaining definitive pathology via needle biopsy or postoperatively

Exclusion Criteria:

  • Pregnant and lactating women
  • Previous history of breast treatment (e.g., surgery, radiotherapy, chemotherapy, or targeted therapy, etc.)
  • Inability to cooperate for MRI examination, or presence of severe artifacts (e.g., motion artifacts, metal artifacts) in the imaging data that precludes parameter measurement.
  • The lesion cannot be clearly identified or delineated on MRE or vMRE images
  • Complicated by severe cardiac, hepatic, or renal diseases, coagulation disorders, or other malignancies.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Differentiation between benign and malignant lesions
Time Frame: From enrollment to the end of surgery
With puncture biopsy or surgical pathology serving as the gold standard, MRI parameters are used to distinguish benign from malignant lesions
From enrollment to the end of surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pathological TNM staging
Time Frame: From enrollment to the end of surgery
Pathological examination information: The pathology results using surgery/biopsy data are the gold standard, and the depth of tumor invasion, lymph node metastasis, and distant metastasis are recorded
From enrollment to the end of surgery
Consistency Between MRE and vMRE in Lesion Measurement and Comparison of Diagnostic Performance
Time Frame: From enrollment to the end of surgery
Intraclass correlation coefficient (ICC); Bland-Altman analysis etc.
