NCT02380209

Brief Summary

Evaluate the feasibility of translating preclinical Chemical Exchange Saturation Transfer (CEST) MRI protocol designed to estimate tumor extracellular pH (pHe) to a clinical MRI scanner in women with early stage breast cancer. Assays are used to quantify tumor acidosis.

Outcome Measures

Primary Outcomes (1)

  • pH measurement of the tumor will be measured by the CEST MRI.

    pH estimate of the tumor

    2 weeks

Secondary Outcomes (1)

  • Correlate tumor pH as estimated by CEST MRI with protein and RNA based markers for acidosis and hypoxia.

    2 weeks

Study Arms (1)

Optimization

EXPERIMENTAL

CEST MRI of the breast for estimation of tumor pH.

Other: CEST MRI

Interventions

CEST MRI will be performed on patients prior to surgical resection of their tumor

Also known as: iopromide, Ultravist, Isovue
