Patients should be counseled to stay at least 15 cm (6 inches) away from devices with strong electrical or magnetic fields such as strong magnets, loudspeaker magnets, Electronic Article Surveillance (EAS) system tag deactivators, arc welders, induction furnaces, and other similar electrical or electromechanical devices. ...

There was no history of acute trauma to the pelvic or acetabular region. Magnetic resonance imaging revealed bilateral fragility fractures, with the left more prevalent than the right. ...
According to our Advanced Practice Provider (APP) Advisory Board, imaging review, a key aspect of mild® patient candidate identification, is often not included in initial schooling. To help APPs learn the basics of image review, become more familiar with identifying anatomical landmarks, and understand how to confirm if a patient is a candidate for the ...
BACKGROUND Non-invasive techniques like urinary biomarkers and multiparametric Magnetic Resonance Imaging (mpMRI) show great promise for the detection of clinically significant prostate cancer (PCa), leading to a reduction of over-diagnosis and over-treatment. ...
Meanwhile, only 13 (43.2%) of 38 facilities used handheld magnets for physical screening, 25 (65.8%) of MRI units did not use any kind of ferromagnetic metal detection systems. ...
A number of cardiac tests may be used to make a diagnosis, including non-invasive methods such as X-ray, magnetic resonance imaging (MRI), echocardiograms (EKG), electrocardiogram (ECG) and genetic testing, or minimally invasive procedures, such as cardiac catheterization. ...
This is an observational cohort study looking at women, 30 years of age or older with a concern or at risk of suspected breast disease or breast cancer. The proposed study aims to examine the diagnostic performance of non-contrast MRI in breast disease by applying quantitative multiparametric MRI ...
This study aims at developing new and improved MRI imaging protocols in order to obtain better quality images and improved/reduced scan time. We will also assess whether multi-parametric MRI imaging of multiple organs gives the same results when it is repeated on the same person after a period of time, and when it is performed on the same person in different MRI scanners. We hope that, by running ...
Methods A retrospective review of hospital records from a single institution was performed to identify all patients that underwent implantation of a DASCOR device between 2006 and 2009. Clinical outcome and imaging data were gathered to assess device performance of the DASCOR device over an extended period of time. Clinical data were assessed using a visual analog scale for back ...
Introduction Magnetic resonance imaging offers a wide variety of contrast mechanisms to study soft tissue in the body. Using the complex data from the SWI scans, it is possible to produce magnetic source images using a novel reconstruction method that takes the phase data and reconstructs what is referred to as a ...
Guidance for Industry and Food and Drug Administration Staff Introduction This guidance document provides Food and Drug Administration’s (FDA’s or the Agency’s) recommendations on testing to assess the safety and compatibility of medical devices in the Magnetic Resonance (MR) Environment and the recommended format for Magnetic ...
Examples of less invasive methods that have been explored include sonomyography, mechanomyography, electroencephalography, near infrared spectroscopy, magnetoencephalographic, and functional magnetic resonance imaging (Silva et al., 2005; Fang et al., 2015). Although all techniques have their own benefits and limitations, the main focus of this ...
Nitinol (Nitinol) alloys have many material and device characteristics, for example, kinking resistance, stress constancy, dynamic interference, deflection stiffness, magnetic resonance imaging (MR1) compatibility, radiopacity and biocompatibility. ...
MRI Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a very large magnet, radio waves, and a computer to produce detailed, cross-sectional, and three-dimensional images of organs and structures within the body. ...
Hospitals throughout the world, working towards improving the lives and outcomes for cancer sufferers, are using MRI (magnetic resonance imaging) scanners to diagnose and stage cancer in patients. Whilst the magnetic fields and radio waves used by MRI scanners pose no risk to humans, scanners’ cooling system potentially do, ...
Methods Radiosurgery plans that delineated the cranial nerve from a single patient’s fused computedtomography and magnetic resonance imaging (CT-MR) data set were planned on both the ZAP-X and CyberKnife, with the latter serving as a validated benchmark. ...
A new type of polymer designed by MIT chemists incorporates a special monomer (yellow) that helps the polymers to break down more easily under certain conditions. (Image credit: Demin Liu) A chemical reaction known as ring-opening metathesis polymerization (ROMP) is useful for developing innovative polymers for numerous uses such as high-performance resins, nanofabrication, and ...
Magnetic resonance imaging (MRI) is a frequently used diagnostic imaging modality that may be an alternative to other types of radiologic imaging (e.g., computerized tomography, nuclear medicine imaging). It can detect soft tissue characteristics (e.g., inflammation), and because ...
The need for precision during brain surgery has led to an increase in computer-assisted surgeries (CAS). This technique involves using imaging technologies such as magnetic resonance imaging (MRI), computerised tomography (CT) or positron emission tomography (PET) to generate an image of the patient's brain. ...
In the light of new studies indicating effects on the human brain with just of dose of SSRIs using magnetic resonance imaging (MRI) scans, we discuss possible reasons for the discrepancy in former results in relation to the “read‐across” hypothesis, variation in biomarkers used, modes of uptake, phylogenetic distance, and the affinity to ...
