Evaluation of Perforator Phase Contrast Angiography in Developing Surgery Plans for Patients With Breast Cancer Undergoing Breast Reconstruction With Free-Flap Methods After Mastectomy

PRIMARY OBJECTIVES: I. To assess the quality of surgical plans prepared under the guidance of the non-contrast, ionizing-radiation-free perforator phase contrast angiography (pPCA) against plans based upon the current gold standard, the X-ray-based, contrast-enhanced computed tomographic angiography (CTA). SECONDARY OBJECTIVES: I. To assess whether pPCA is more accurate than CTA for vessel size measurement. II. To assess the impact of pPCA-based surgical planning on the clinical outcomes of abdominal-based free flap surgery. III. To obtain and analyze cost/expenditure information for pPCA-guided abdominal-based free flap procedures. OUTLINE: Patients undergo standard of care CTA and undergo pPCA MRI for up to 60 minutes before surgery. After surgery, patients will be followed up at 24 hours, 1 week, 3 months, 1 year and 2 years.
