Detection of Breast Microcalcification Under Ultrasound Using Power Doppler and Acoustic Resonance Imaging
Abstract
Frequently, intraductal breast cancer (DCIS) presents only as calcifications without an associated mass. As DCIS represents as much as a third of mammographically detected cancer, it would be efficacious to image microcalcifications by as many modalities as possible in order to allow flexibility in image guided biopsies. We have developed a technique utilizing acoustic resonance to visualize microcalcifications under ultrasound. Our work with phantoms show that ultrasound coupled with acoustic resonance can reliably demonstrate small calcific particles for targeting and biopsy. After doing extensive evaluation with phantom models, we have begun evaluating and optimizing the technique of imaging breast microcalcifications with power Doppler and acoustic resonance using ultrasound in patients with breast microcalcifications prior to biopsy.
