Filter by:The SAVI Reflector is a nonradioactive infrared (IR)-activated electromagnetic wave device that can be implanted in the breast or lymph nodes under image-directed guidance, typically by mammography or sonography. Intraoperatively, the SCOUT hand-held device is then percutaneously applied to the breast or lymph node, creating an audible signal on the device console with a gradient which correlates to distance (in mm) from the target lesion and marker. The Savi Scout surgical guidance system was approved by the U.S. Food and Drug Administration in 2014. Furthermore, it was approved for long term use, with no restrictions on the length of time in 2017. The system consists of an implantable reflector with a 4-mm body size, preloaded in a 16-gauge deliverable needle, a hand-held probe and a console. The reflector consists of an IR light receptor, resistor switch and two antennae. This is placed into or near the target through a 16G needle under mammographic or sonographic guidance. The hand-held probe detects pulses of infrared (IR) light and radar wave signals, received by the console system, which then emits and receives signals back to the reflector to provide real time localization and target proximity information to the surgeon. The SCOUT console provides audible and visual feedback intraoperatively, the frequency of which increases as the handheld reader approaches the implanted reflector. After excision of the breast lesion, the handheld reader can be used to immediately confirm removal of the reflector, present in the lumpectomy specimen, and subsequent quiescence of radar signal in the breast.
This study evaluates a second review of ultrasound images of breast lesions using an interactive "deep learning" (or artificial intelligence) program developed by Samsung Medical Imaging, to see if this artificial intelligence will help the Radiologist make more accurate diagnoses.
The purpose of this registry study is to collect use and clinical outcomes data following breast lesion excision or sampling with the Intact BLES.
The purpose of this post-marketing study is to provide prospective evidence that the Magseed and Sentimag® is effective for lesion localization in patients undergoing surgical excision of a breast lesion and to summarize measures of product safety and performance.
This research protocol is designed to evaluate a novel imaging camera, only one of three of it's kind in existence, in the diagnosis of breast cancer. The Molecular Breast Imaging Camera (MBI) is a gamma camera that images accumulation of 99mTc-Sestamibi, a radiopharmaceutical with high affinity for tissues of high cellularity and mitochondrial content; a common characteristic of breast cancers. This camera represents a significant advancement over its predecessors as it has improved imaging geometry since it can be in direct contact with breast tissue and improved gamma photon detection capability through the use of cadmium zinc telluride (CZT) crystals (a semiconductor material) instead of NaI used in standard gamma cameras. This project involves imaging patients with a baseline population risk of breast cancer, referred for myocardial perfusion imaging (MPI). This is possible because 99mTc-sestamibi is also used to image myocardial tissue. After the MPI study is performed to standard clinical specifications, the patient is simply imaged with the MBI. The primary endpoint of this project is to assess acceptability of this imaging device by the patient through the use of a patient survey. Secondary endpoints are to correlate any findings on the MBI studies with standard breast imaging modalities including mammogram, ultrasound, and MRI. Image quality will be evaluated by the interpreting physicians. Also, in an effort to reduce radiation absorbed dose to the female breast, low injected dose images, obtained through post-processing by reframing acquired images, will be assessed for acceptable image quality and diagnostic accuracy.
Magnetic resonance imaging (MRI) is commonly used for the detection of breast lesions in genetically high-risk women due to its high sensitivity. As non-cancerous conditions including normal changes due to a woman's menstrual cycle may have the appearance of cancer on MR images, a biopsy (generally performed under ultrasound-guidance) of the suspicious mass is required for definitive diagnosis. However, only a limited percentage of MRI-visible lesions are also visible on ultrasound (US). Even if found, it is often unclear whether the lesion identified on US corresponds to the MRI-detected lesion in question. The investigators have developed a visualization tool to assist the visualization of MRI-detected lesions in US-guided procedures (e.g., biopsy). This tool provides a simultaneous display of the previously acquired MRI data alongside real-time US images. The investigators propose a pilot study to assess the usefulness of this tool in identifying MRI-detected lesions using real-time US-guidance.
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.
This study will investigate the association of angiogenesis in breast cancer measured by magnetic resonance imaging and biomarkers with long-term prognosis of patients.
