Summary

MRI is a well-established method in breast imaging. It gives excellent morphological information but does not reflect the metabolic activity leading to high proportion of false positive results. PET-CT fulfills this gap but suffers from low resolution and the risk of radiation damage. Lately, chemical exchange saturation transfer (CEST) MRI of glucose has been proposed as a new molecular imaging approach for diagnosing tumors given its high sensitivity at the molecular level and the known enhanced glucose uptake by tumors. Several glucose analogs were examined as possible candidates for imaging of breast tumors. One of the most promising agent for CEST-MRI is glucosamine (GlcN); owing to its phosphorylated products that accumulate in breast tumors, it enables to reflect their metabolic profile. In preclinical experiments glucosamine exhibits enhanced CEST signals in 4T1 and MCF7 implanted breast cancer cells in mice. Its potential for the human clinical application is strengthened by its lack of toxicity. Here the investigators propose to test the method for human subjects on a clinical MRI setup. The goal of this study is to develop innovative molecular imaging modality based on CEST-MRI of GlcN for the detection of breast tumors. The investigators will use the newly developed CEST-MRI modality for the detection of benign and malignant breast cancer in a clinical MRI scanner.

Conditions

  • Malignant Tumor of Breast
  • Benign Breast Lumps
  • High-Risk Breast Cancer

Interventions

DEVICE

MRI scan

All patients will be scanned twice during the same MRI session, before and 2 hours after taking glucosamine orally. In addition to the CEST scans with glucosamine, patients will undergo MRI scans with the standard contrast agent of gadolinium. This procedure will be done following the CEST scan
