Active clinical trials for "Breast Cyst"

The trialed investigational medical imaging device is a low-power microwave breast imaging system for cancer screening purposes. It is an active device which uses non-ionizing radiation. Microwave imaging is an emerging imaging modality for the early detection of the breast cancer. The physical basis of microwave imaging is the dielectric contrast between healthy and cancerous breast tissues at microwave frequencies. Microwave imaging can potentially be used for monitoring neoadjuvant chemotherapy treatment, breast health monitoring, and for routine screening and diagnosis of the breast cancer at the early-stage. The non-invasive and the non-ionizing characteristics of microwaves should allow for frequent scans of the breast using microwave imaging, unlike X-ray mammography. In addition to safety, microwave imaging does not require uncomfortable breast compression and it is potentially a lower-cost modality. This is a first-in-human clinical test of the investigational device, which has been so far tested only with experimental phantoms modelling the human female breast. The clinical data that will be collected in the context of this study is intended to provide early safety information for the investigational medical imaging device. In addition, this exploratory data will guide the refinement of the device hardware and the imaging algorithm design, before decision to proceed (or not) with further clinical tests. Furthermore, this study will be used to guide sample size calculation for a subsequent study designed to evaluate efficacy should that appear warranted once this study is completed.

The study purpose is to help in the developement of 3 dimensional breast ultrasound imaging.

The MARIA breast imaging system is a Conformité Européenne (CE)-marked radio-frequency (RF) medical imaging device. The system employs an electromagnetic imaging technique that exploits the dielectric contrast between normal and cancerous tissues. The performance and imaging characteristic differences between the M5 and M6 versions of MARIA are not yet well demonstrated in the clinical environment, particularly with regards to cysts. The evaluation of some aspects of this potentially important new technology will occur in this comparative technical study. Further, the dielectric constant of cyst fluid is currently not well understood and obtaining readings from aspirated cyst fluid in applicable patients will be attempted.

This is a pilot, simulated breast cancer screening study. The goal of the study is to explore these scanning modalities: 1) Combined digital breast tomosynthesis(DBT)/dual-sides 3 dimensional-automated ultrasound(AUS) 2. Explore the utility of photoacoustic imaging as an adjunct to digital breast tomosynthesis(DBT)/ultrasound(US)alone.

The purposes of this study is to establish normal optical values of breast tissue in the general population. This will allow for establishing normals for breast composition, and is expected to be useful in the classification of breast lesions into groups such as cysts, benign growths, inflammatory lesions, and possibly early breast cancer.
