6 Clinical Trials for Various Conditions
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 study purpose is to help in the developement of 3 dimensional breast ultrasound imaging.
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.
Screening for breast cancer improves early detection of aggressive cancers and has been shown to reduce breast cancer related mortality. Currently, mammography is the most effective way of detecting early stage, non palpable breast cancers. However, mammography only reveals the breast structure, and cannot say much about the breast physiological state. We propose Tomographic Optical Breast Imaging (TOBI) as an inexpensive, patient friendly technique that is non-invasive and does not use non-ionizing radiation. TOBI uses near infrared light and by measuring how such light passes through the breast, images of blood volume and hemoglobin oxygenation can be obtained. In this study, TOBI is combined with digital breast tomosynthesis (DBT, a form of 3D mammography) and our hypothesis is that the TOBI-DBT combined images can be used to diagnose breast cancer with significantly improved sensitivity and specificity compared to DBT alone.
* History of clinical breast pain for at least the last six months. * At least six days of moderate or severe breast pain per cycle. * Fibrosis, cysts, nodules involving at least 25% of the surface of one breast. * Euthyroid with no prior history of thyroid disease. * Six months of daily therapy with molecular iodine. * Placebo controlled vs active (1:1).
This study will be focused on assessing the molecular, physiological, and emotional correlates of an intensive meditation experience in the context of a retreat setting in a large 2000 plus-person cohort comprised of healthy and clinical populations.
