Contrast Enhanced Mammography

Abstract: Contrast-Enhanced Dual Energy Mammography (CEDEM) is a development of digital mammography. By using dual energy (conventional low-energy mammography plus high-energy mammography) after the administration of a bolus of intravenous iodinated contrast medium, a morpho-functional image of the breast is acquired. This technique joins the high spatial resolution of conventional digital mammography with functional information based on neoangiogenesis. The indications of this technique for clinical use include: problem–solving technique after inconclusive mammography, preoperative assessment of breast cancer, follow-up of scars after conservative treatment, and follow-up of intermediate-risk patients (borderline histological lesions, such as lobular carcinoma in situ, atypical ductal or lobular hyperplasia, and positive family history of breast cancer). In fact, the majority of indications are those of MRI, including the contraindications for MRI (pacemakers, claustrophobic patients, etc.). Nevertheless, CEDEM has some limitations: The sensitivity is lower for ductal carcinomas in situ, lesions out of the field of view of the detector are missed, and some benign lesions can enhance after contrast administration. CEDEM is contraindicated for patients allergic to iodine as well as for patients with renal insufficiency.

Learning objectives:

1. To become familiar with Contrast-Enhanced Dual Energy Mammography (CEDEM)

2. To learn the main indications for this technique

3. To learn the main limitations of CEDEM

Abstract: Are you considering adding Contrast Enhanced Mammography to your department? Have you just started and would like to see how others are using it? Perhaps, You've been using it for a while, but would like to compare our workflow with yours? Dr. Noel Bergquist, an assistant professor at the University of Tennessee at Knoxville's Breast Center, will present a diverse series of cases, after a brief review of Siemens' Titanium Contrast Enhanced Mammography (TICEM). The majority of current uses will be covered in the included 8 - 10 cases.
