Comparison of Contrast Enhanced Digital Breast Tomosynthesis and Magnetic Resonance Imaging in Patients With Known Breast Lesions
UNC Lineberger Comprehensive Cancer Center
Summary
The purpose of this pilot study is to compare radiologist confidence level in evaluating patients with known breast lesions between contrast enhanced digital breast tomosynthesis (CE- DBT) and contrast enhanced dynamic magnetic resonance imaging (CE-MRI) acquired as a part of a standard clinical workup.
Description
This is a pilot study of CE-DBT scans to evaluate its utility relative to breast CE-MRI. Twenty women who have planned or received conventional breast MRI imaging at UNC Hospitals will be recruited for the study. Participants will be scanned with the DBT system after the administration of iodinated contrast agent. Images will be acquired prior to the administration of contrast, followed by at approximately 2 minutes and 5 minutes. For the purposes of this study, imaging will focus on a single breast to simplify data acquisition.
Eligibility

- Healthy volunteers
- No
Inclusion Criteria: * Women at least 18 years old * Planned or received conventional breast MRI at UNC Hospitals within 3 months prior to or after the research scan * Suspected breast lesion based on prior imaging (BIRADS 4 or greater) * Able to provide written informed consent Exclusion Criteria: * Severe untreatable claustrophobia * Implanted metallic devices, parts, vascular clips, or other foreign bodies (including breast implants) * Known hypersensitivity to iodinated contrast agent or to any component of iodinated contrast refractory to standard medications (antihistamines, steroids)…
Interventions
- DrugIohexol 350 Mg/mL Injectable Solution
Participants will be scanned with the digital breast tomosynthesis (DBT) system before and after the intravenous administration of iodinated contrast agent, iohexol 350mg I/mL at a dose of 1.5 mL/kg body weight. Images will be acquired of the breast of interest prior to the administration of contrast, followed by at approximately 2 minutes and 5 minutes after administration. For the purposes of this study, imaging will focus on a single breast to simplify data acquisition.
