Magnetic resonance imaging and intraocular foreign bodies.
We conducted in vitro and in vivo experiments to study magnetic resonance imaging of intraocular foreign bodies. Diamagnetic and paramagnetic foreign bodies were imaged without artifact and without movement during the imaging process, while ferromagnetic foreign bodies produced large amounts of artifact that prevented meaningful images. All fetromagnetic foreign bodies moved during in vitro ima...
متن کاملUpper aerodigestive magnetic foreign bodies in children.
OBJECTIVES/HYPOTHESIS Small, powerful magnets are increasingly available in toys and other products, and are responsible for increasing numbers of foreign body injuries in children. Small, spherical, neodymium magnets available since 2008 are of particular concern. We aimed to identify all cases of upper aerodigestive foreign bodies at our institution over 15.5 years of study. STUDY DESIGN Ca...
متن کاملIntracapsular Extraction of Intralenticular Magnetic Foreign Bodies.
INTRALENTICULAR magnetic foreign bodies if left untreated lead in most instances to total cataract formation, siderosis, or as a later complication, loss of the eye. Since the use of the magnet has been developed, and powerful hand instruments have made manipulation easier, intralenticular magnetic foreign bodies have been removed by this means via the anterior route. The risk of siderosis is t...
متن کاملForeign Bodies
When people ingest or insert foreign bodies, a brief history may be sufficient to establish the diagnosis, guide initial management decisions, and predict the process required for definitive removal. Sometimes, however, diagnosis and management of a foreign body might require a meticulous history and insightful care. Those at higher risk of having a foreign body include neurologically impaired ...
متن کاملHigh Frequency Amplitude Detector for GMI Magnetic Sensors
A new concept of a high-frequency amplitude detector and demodulator for Giant-Magneto-Impedance (GMI) sensors is presented. This concept combines a half wave rectifier, with outstanding capabilities and high speed, and a feedback approach that ensures the amplitude detection with easily adjustable gain. The developed detector is capable of measuring high-frequency and very low amplitude signal...
