15 Clinical Trials for Various Conditions
The study is a prospective multi-center open-label single-arm study. The subjects will be enrolled and assigned into a single study group. Subjects will be required to complete four (4) treatment visits and three follow-up visits, 2 months, 6 and 12 months after the final treatment. At the baseline visit photographs of the abdomen will be taken. In addition, adipose/muscle layer thickness will be measured with the magnetic resonance imaging and the subject's weight will be recorded. Safety measures will include documentation of adverse events (AE) including subject's experience of pain or discomfort after the procedure. Following each treatment administration and at the follow-up visits, subjects will be checked for immediate post-procedure adverse event assessment. In addition, at the last therapy visit, subjects will receive Subject Satisfaction and Therapy Comfort Questionnaires to fill in. Post-procedure evaluation (follow-up visits) will be conducted 2, 6 and 12 months after the final treatment. During those visits, magnetic resonance imaging, photographing and weight measure will be conducted. Subject Satisfaction Questionnaire will be given at every follow-up visit.
Registry intends to prospectively collect data regarding the safety of magnetic resonance imaging (MRI) studies in patients with cardiac pacemakers on implantable cardioverter defibrillators.
Ferromagnetic Implants such as permanent pacemakers (PPM's) and Implantable Cardioverter Defibrillators (ICD's) have traditionally been accepted as contraindications to Magnetic Resonance Imaging (MRI) due to safety concerns. Over the past several years, MRI safety has been established in patients with pacemakers or ICD's but only in patients in whom strict vetting procedures were implemented. These vetting procedures were initially developed to eliminate devices, leads and device/lead circumstances thought to carry increased risk. Over recent years however, objective scientific evidence has failed to support this concern raising the question as to whether or not these vetting procedures are necessary. Investigators hypothesize that in view of the existing objective scientific data, evolution of device technology and the fact that the investigators have scanned more than 2,000 devices safely (RPN03-08-11-12 and 00051707) ICD's and pacemakers and device circumstances previously excluded from MRI protocols can be safely scanned without prior vetting. This is a prospective, non randomized, cohort study. Seventeen Hundred participants with an implanted ICD or pacemaker and a clinical need for MRI will be included in the study. Unlike previous studies where strict vetting procedures were implemented pre-procedure, All patients with a pacemaker or ICD and clinical need for an MRI will be eligible for inclusion in the study provided participants meet standard MRI inclusion/exclusion safety criteria.
This is a database study of clinically indicated MRIs on patients with permanent pacemakers and implantable cardioverter defibrillators.
The results of this imaging and treatment planning protocol will aid in developing procedures for patient localization and future clinical implementation of low-field MRI to confirm positioning prior to radiation treatment. Images acquired during this study may aid future study design for adaptive planning based on low-field MRI images. Moreover, results of this imaging and treatment planning may lead to guidance on optimal use of this novel device.
The purpose of this study is to evaluate the effectiveness of Focal-Fusion Bx at detecting clinically significant prostate cancer in a standard clinical environment.
The primary objective of the study is to determine the safety of MRI in patients with non-MRI conditional pacemakers. The secondary objective is to determine if there are clinically relevant parameter changes in the devices.
The research goal is to continue to add to the extensive body of peer-reviewed evidence that demonstrates MRI may be safely performed in patients with cIEDs, after they have been evaluated and cleared by cardiology. This study will allow the researchers to collect data from the facilities ongoing clinical practice regarding the number and types of any adverse clinical reactions, and also to document any changes in the implanted cardiac device that may have occurred during the MRI scan. The researchers will also be assessing the results of the MRI and how the imaging findings impact patient care and the clinical outcome of the patient. This data will then be presented to the FDA and the Centers for Medicare and Medicaid Services to further influence federal guidelines and payment structures.
Hippocampal-avoidance whole brain radiation therapy (HA-WBRT) limits radiation dose to the hippocampal-avoidance region while still delivering therapeutic doses of radiation to the whole brain. When used in addition to prophylactic memantine, this technique has been shown to better preserve cognitive function in patients with brain metastases outside of the hippocampal-avoidance region with no difference in intracranial progression-free and overall survival. However, HA-WBRT requires considerably longer planning time when compared to conventional WBRT (5-10 business days, compared to next-day), and studies have shown that brain metastases can grow in as rapidly as one week. A proposed solution for quicker initiation of HA-WBRT is the use of simulation-free radiation treatment planning, in which pre-existing diagnostic images are used to generate the radiation treatment plan (as opposed to acquiring planning-specific image sets). This will be paired with the use of artificial intelligence (AI)-assisted semi-automated planning using the FDA-approved treatment planning system called Ethos Therapy. The investigators have developed an institutional HA-WBRT auto-planning template, which has been retrospectively validated for the creation of plans that are compliant with the gold standard NRG Oncology CC001 clinical trial and are dosimetrically comparable to traditional HA-WBRT plans. Semi-automated plans will be constructed using diagnostic imaging, which will be refined as needed (adjustments for difference in gross head positioning between diagnostic imaging and radiation treatment positioning, etc.) while the patient is on the treatment table at fraction one using adaptive radiation planning. Adaptive radiotherapy is standard-of-care practice for other disease sites. The purpose of this study is to demonstrate the feasibility and safety of a simulation-free workflow for HA-WBRT that is AI-assisted and semi-automated.
Researchers are trying to determine if heart injury occurs in subjects with cardiac implantable electronic device (CIED), such as a pacemaker or implantable cardioverter defibrillator (ICD), who undergo a magnetic resonance imaging (MRI).
This study will use magnetic resonance imaging (MRI) to evaluate changes in gluteal muscle following the treatment with HIFEM stimulation for aesthetic improvement of buttocks.
The purpose of this study is to evaluate product performance of Magnetic Resonance (MR) Conditional Cardiac Implantable Electronic Devices (CIED) following 3 tesla (3T) MRI exposure. This will be achieved by evaluating the changes in pacing capture threshold (PCT) measurements following 3T MRI scan exposure. This study is required by FDA as a condition of approval of 3T MRI compatible labeling of applicable CIED systems. This study is conducted within Medtronic's post-market surveillance platform, the Product Surveillance Registry (PSR).
Screening Brain magnetic resonance imaging (MRI) with Fluid-attenuated Inversion Recovery (FLAIR) and Susceptibility Weighted Imaging (SWI) sequences will be performed pre and post season on high school football players. One set of players will wear the Guardian Cap on their five star rated helmets and the other will wear five star rated helmets only. The investigators will compare outcomes of ImPACT scores and MRI findings between the two groups to see if there is a statistical difference in reduction of injury and to establish what the baseline level of MRI findings related to injury from high school football is as well as what the baseline level of injury is prior to the start of the season.
