Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
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 ...
MRI uses three electromagnetic fields: a very strong (typically 1.5 to 3 teslas) static magnetic field to polarize the hydrogen nuclei, called the primary field; gradient fields that can be modified to vary in space and time (on the order of 1 kHz) for spatial encoding, often simply called gradients; and a spatially homogeneous radio-frequency ...
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 ...
Between 2000 and 2005, ownership or leasing of MRI scanners by non-radiologists grew by 254%, compared with an 83% increase among radiologists. By 2005, non-radiologists performed more than 384,000 MRI examinations on units they owned or leased, and their share of the private-office MRI market had increased from 11% in 2000 to 20% in 2005.
