Schematic diagram of a conventional MRI scanner. Not shown are the electronic control systems and service plant (chillers, etc.) these are usually installed in a seperate room. 19:42, 6 January 2007: 2,980 × 4,213 (34 KB) ChumpusRex: Schematic diagram of a conventional MRI scanner.
All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
Phase-contrast magnetic resonance imaging: PC-MRA: Two gradients with equal magnitude, but opposite direction, are used to encode a phase shift, which is proportional to the velocity of spins. [29] Detection of aneurysm, stenosis, or dissection (pictured). [28] ^
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to generate images of the organs in the body.
Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...
