Contrast-Enhanced Digital Mammography(CEDM) vs Contrast-Enhanced Breast MRI(CE-MRI) in Breast Cancer

N/ACompletedNCT01970670

Stanford University50 enrolled

Overview

The primary objective is to determine how accurately one can estimate the size of the index tumor on preoperative imaging in patients with known breast cancer, using pathology as a reference standard. The primary endpoint, which will be measured on CEDM,and CE-MRI, is the maximum diameter (mm) of the index tumor.
