Some modern scanners have larger bores (up to 70 cm) and scan times are shorter. A 1.5 T wide short bore scanner increases the examination success rate in patients with claustrophobia and substantially reduces the need for anesthesia-assisted MRI examinations even when claustrophobia is severe.

MRI’s magnetic force pulled the bed and nurse into the machine
The intended treatment for Norris was 35 Gy to be delivered by a linac machine to the whole of the central nervous system to be delivered in twenty equal fractions of 1.75 Gy, which was to be followed by 19.8 Gy to be delivered to the tumor only (in eleven fractions of 1.8 Gy). In the first phase of the treatment a 58% overdose occurred, and ...
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
Doctors are warning patients not to wear spandex clothing when coming in for a magnetic resonance imaging (MRI) procedure. Fabrics that use spandex often have metallic threads that could react ...
Local reports claim the man was yanked towards the machine by a magnetic force after he entered the room while carrying an oxygen tank.
Portable magnetic resonance imaging (MRI) is referred to the imaging provided by an MRI scanner that has mobility and portability. [1] [2] [3] It provides MR imaging to the patient in-time and on-site, for example, in intensive care unit (ICU) where there is danger associated with moving the patient, in an ambulance, after a disaster rescue, or in a field hospital/medical tent.
Ghosting is a multidimensional artifact that occurs in the MRI in the phase-encoded direction (short axis of the image) after applying the Fourier transform. When the phase of the magnetic resonance signal is being encoded into the 2D or 3D Fourier image, a mild deviation from the actual phase and amplitude may occur.
