47 Clinical Trials for Various Conditions
This prospective, blinded, single-arm study aims to test the performance of nanomechanical phenotype in predicting tumor type, tumor aggressiveness, and neoadjuvant treatment response compared to the gold standard of histopathological assessment. The study involves patients with suspicious breast lesions who will undergo a breast biopsy procedure indicated by standard of care. The nanomechanical phenotype will be measured on the freshly obtained breast biopsies or tissue from breast surgeries.
The purpose of this pilot study is to compare radiologist confidence level in evaluating patients with known breast lesions between contrast enhanced digital breast tomosynthesis (CE- DBT) and contrast enhanced dynamic magnetic resonance imaging (CE-MRI) acquired as a part of a standard clinical workup.
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.
The purpose of the project is to compare Radiofrequency identification device (RFID) localization technique with the current clinical standard wire localization technique. The Investigator's hypotheses is that the RFID localization technique is non-inferior to wire localization for breast lesions (tumors). The study will be conducted in two parts. The purpose of Part A is for physician training with the RFID device. Nine subjects will undergo RFID and wire localization prior to breast lesion excision. This will allow the breast radiologists and surgeons to become comfortable with RFID device placement and retrieval. Additionally, the investigators will pilot the data collection surveys and chart review methodology to be used in Part B. The purpose of Part B is to conduct a randomized clinical trial to assess whether RFID localization is non-inferior to wire localization for breast lesions. For this part, sixty subjects will be randomized to RFID (N=30) or wire localization (N=30) at time of enrollment. Surveys will be used to gather data from participants, radiologists, surgeons, and technologists/mammography nurses. A variety of data will be collected including, but not limited to, information on tumor size, location, depth; subject demographics; adequacy of tumor margins, re-excision rates, accuracy of wire or chip placement, and surgical complications.
The purpose of this registry study is to collect use and clinical outcomes data following breast lesion excision or sampling with the Intact BLES.
This pilot clinical trial studies radiofrequency technology in locating non-palpable breast lesions in patients undergoing surgery. Placing a miniature radiofrequency tag or microchip in the breast lesion before surgery and using a handheld device to guide doctors during surgery may improve surgical outcomes in patients with non-palpable breast lesions.
The goal of the study is to compare the radiologist confidence level in evaluating patients with known breast lesions using a carbon nanotube x-ray based stationary breast tomosynthesis imaging device. The comparison will be made against conventional mammography acquired as a part of a standard clinical workup. One hundred patients who are to have a clinical surgical breast biopsy will be recruited for the study. A reader study will be performed to evaluate the ROC characteristics of the system.
The goal of this investigation is to obtain clinical data to show the Health Beacons Radiofrequency Identification (RFID) Localization System is safe and performs as intended as a localization device for marking and retrieving a non-palpable surgical target from the breast.
The purpose of this study is to show that improvements in the molecular breast imaging (MBI) technology will allow reduction of the administered dose of Tc-99m sestamibi while maintaining a sensitivity of 90% for tumor detection.
The purpose of this study is to develop a computer-aided diagnosis system to find breast lesions, including masses and microcalcifications, which hopefully will improve breast cancer detection and classification.
The study will evaluate and refine a breast screening and diagnosis device.
Our hypothesis is that the addition of ShearWave Elastography (SWE) to a conventional breast ultrasound examination provides useful information for the radiologist when imaging lesions in the breast, as compared to conventional grayscale ultrasound alone.
RATIONALE: Cryosurgery kills cancer cells by freezing them. Cryosurgery followed by lumpectomy or mastectomy may be an effective treatment for breast lesions. PURPOSE: Phase I trial to study the effectiveness of cryosurgery in treating women who have breast lesions.
RATIONALE: Biopsy is the removal of cells or tissue for examination under a microscope. It is not yet known which type of breast biopsy is more effective for diagnosing breast lesions. PURPOSE: Randomized diagnostic trial to compare the effectiveness of two different types of biopsy in patients who have breast lesions that cannot be felt upon examination.
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.
The purpose of this new imaging method is to provide physicians with additional information not available with standard imaging methods. This includes information about the make up of different breast diseases. Using spectroscopy data, it may be possible to tell the difference between benign conditions of the breast from malignant tumors and provide more accurate information than can be obtained with regular MRI. Along with the MRI a new method of evaluating the images or pictures will be used. This new method is called spectroscopy and is used routinely on other parts of the body such as the prostate and brain. Pictures produced with this sequence look different than the regular MRI pictures. Performing spectroscopy on a 1.5T magnet adds another imaging sequence (another scan) to the routine MRI protocol, thus increasing exam time (extra 10-15 minutes). This study will enroll patients who are scheduled for a Magnetic Resonance Imaging (MRI) examination ordered by their primary physician.
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 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.
Purpose: This study will evaluate how measurements of tissue stiffness, viscosity, and anisotropy using non-invasive ultrasound imaging correlate with breast tumor malignancy and response to chemotherapy. Participants: Up to 200 women with benign or malignant breast tumors for arm 1 and up to 50 women undergoing neoadjuvant chemotherapy in the breast for arm 2 will be recruited. Procedures (methods): The research team will use an ultrasound scanner to acquire non-invasive elastography data from the breast of each subject, testing a range of transducer rotation angles. Transducer position will be monitored using a position sensor during imaging.
The purpose of this study is to demonstrate that BVN G-1000 can precisely and consistently measure the position of female breast lesions regardless of patient rotation and probe angle during ultrasound examination.
The primary aim of this study is to evaluate if VTIQ in addition to BI-RADS® categorization can improve the diagnostic accuracy with respect to detection of malignancies, in particular for BI-RADS® categories 3 and 4a. The idea of the study is to restage all patients in categories 3 and 4a according to a predefined VTIQ cut-off value of ≥ 3.5 m/s (37 kPa).
This study will evaluate the potential role of a long acting anesthetic (ropivacaine) in providing an extended period of pain relief for patients undergoing ultrasound guided core biopsy of the breast.
A combined molecular breast imaging / ultrasound system will enable coregistration of a functional abnormality seen on Molecular Breast Imaging (MBI) with the corresponding anatomical abnormality seen on ultrasound.
In this study, participants, who are scheduled to have a breast biopsy, will have several extra spot mammogram images taken of the suspicious area. These images will be acquired with varying levels of compression. The images will then be analyzed to determine whether the type of lesion (malignant or benign) can be determined from the image data alone. The biopsy results will be used as a gold standard to determine the true malignancy status
The purpose of this patient tracking program is to monitor long term safety and effectiveness of the Novilase™ device and method in real world application.
The purpose of this study is to see if dynamic contrast enhanced (DCE) MRI imaging makes it possible to distinguish benign conditions of the breast from malignant tumors and provide better information than can be obtained with regular MRI. DCE MRI uses a new way of collecting and analyzing the images or pictures which provides doctors extra information not available with standard imaging methods. This includes information about the blood vessels of different breast diseases. Pictures produced this way look just like the regular MRI pictures. The DCE MRI adds another imaging sequence (another scan) to the MRI examination ordered by your physician to evaluate your breast lesion, thus increasing the exam time (extra 10 min). The information gained from doing the new test, the DCE MRI, will not be used in your treatment and will not affect the type of care you receive for your breast lesions.
RATIONALE: New diagnostic procedures, such as vibro-acoustography imaging, may be an effective method of finding microcalcifications and lesions in the breast. PURPOSE: This clinical trial is studying how well vibro-acoustography imaging works in finding breast microcalcifications and lesions in women.
This study is designed to look at whether it is feasible to observe women with atypical ductal hyperplasia (ADH) of the breast, or whether surgical excision is necessary.
The purpose of this study is to examine for changes in the bone scan after treating with zoledronic acid (Zometa™). This study is designed to show if intravenous (IV) bisphosphonates, which are infused by vein, such as pamidronate (Aredia™) or zoledronic acid (Zometa™), cause changes in the result of bone scans in women with metastatic breast cancer. Both bone scans and the IV bisphosphonates are components of routine care of women with breast cancer that has spread to the bone.
