Ultrasound Breast Imaging - Lesion Characterization
Increasing Exam Specificity
Several new imaging technologies provide information on lesions that is different from and complementary to the information provided by B-mode imaging. This greatly aids in lesion characterization. Key applications include:
- eSie Touch™ elasticity imaging
- Cadence™ contrast pulse sequencing technology (CPS)
eSie Touch elasticity imaging*
A new, real-time, qualitative imaging technique that displays the relative stiffness or hardness of tissues to provide further insight into potential pathology.
In this comparison, a large solid mass with poorly defined borders, is noted on b-mode imaging. The elastogram demsontrates a large stiff mass with clearly defined borders consistent with an invasive ductal carcinoma
Cadence contrast pulse sequencing technology (CPS)**
A real-time imaging technique for contrast agent*** examination that demonstrates vascularity and can be used as an aid in determining treatment steps.
Contrast enhanced ultrasound demonstrates an irregular nodule with spiculated enhanced areas, indicative of malignancy (13MB .avi)
Advances in Ultrasound Breast Imaging
Overview
*Available on the ACUSON Antares™ ultrasound system
**Available on the ACUSON Sequoia™ and ACUSON Antares™ ultrasound systems
***At the time of publication, the US Food & Drug Administration cleared ultrasound contrast agents for use in LVO. Check the current regulation for the country in which you are using the system for contrast agent clearance.
Case Study Spotlight
Cadence CPS technology improves sensitivity at high ultrasound frequencies (>7 MHz needed for breast imaging) by overcoming the challenges associated with the native resonant frequencies of the contrast agents (1.5 MHz – 7 MHz).
