To determine the added value of multivoxel MRS in equivocal breast lesions detected through screening with DCE-MRI. This study will especially focus on young women with a high risk of breast cancer.<br>
The hypothesis is that with the application of a DCE-MRI scan with quantitative multivoxel MRS, 23% of the number of false positive breast lesions and related to that, the number of unnecessary invasive procedures, will be prevented as compared to a regular DCE-MRI.
Achtergrond van het onderzoek
Mammography and dynamic contrast-enhanced Magnetic Resonance Imaging (DCE-MRI) are used as standard modalities for breast cancer screening in the (genetically) high risk women. DCE-MRI has the highest overall negative predictive value (NPV) of all imaging techniques and is therefore able to safely exclude malignancy (NPV > 98%) (7, 8). The problem with DCE-MRI is that enhancement patterns show considerable overlap in malignant and benign breast lesions. Therefore, the majority of the enhanced breast lesions are considered equivocal. Therefore, women may be exposed to uncertainty about outcomes of the screening irrespective of the modality used, resulting in anxiety. A substantial amount of these women will undergo unnecessary invasive procedures in case of an equivocal lesion. Ultrasound-guided biopsy (core needle biopsy) is discomforting and is sometimes accompanied by complications, such as hematomas.
The purpose of the study is to determine the added value of multivoxel MRS in women with increased risk for breast cancer and equivocal enhanced breast lesions detected at screening with standard Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI). Thereby, to decrease the number of false positive breast lesions on DCE-MRI scans with multivoxel MR spectroscopy (MRS) and to prevent unnecessary invasive procedures or unnecessary extended breast surgery.
Doel van het onderzoek
The purpose of the study, therefore, is to determine the added value of multivoxel MRS in equivocal breast lesions detected through screening with DCE-MRI. This study will especially focus on young women with a high risk of breast cancer.
The hypothesis is that with the application of a DCE-MRI scan with quantitative multivoxel MRS, 23% of the number of false positive breast lesions and related to that, the number of unnecessary invasive procedures, will be prevented as compared to a regular DCE-MRI.
The expectation is that women prefer the new non-invasive diagnostic work-up instead of the biopsy, and that this, when implemented in clinical practice will improve the quality of life of the women involved.
