All MRI protocols are not equal; on a previous scan, the device may not have been in the isocenter of the MRI scanner and thereby not exposed to the same magnetic fields and/or electrical currents. Also, while the implanted device or hardware may be MRI compatible, it may interfere with adequate imaging, and a different modality may be more. MRI protocol for a quick stroke assessment corresponds to a short protocol, usually just the DWI/ADC, adopted by some institutions as a complementary tool to the CT imaging in stroke code patients. The aim is to provide additional information to.
Magnetic resonance imaging (MRI) was used to study the hand and wrist in very early rheumatoid arthritis (RA), and the results were compared with early and established disease.

Lesion was homogeneous on all MRI sequences including T2-weighted. Computed tomography (CT) scans of the wrist have been used to assess fusion procedures, foreign bodies, masses, and carpal fractures(1). A study suggested that CT scans allow the imaging of the wrist bones during motion(2). This procedure is essential in the diagnosis of vital carpal instabilities(3) The wrist and MCP joints were prioritised because of their frequent involvement in RA (including early RA), the fact that these joints are included in traditional clinical and radiological scoring systems in RA, and the large amount of MRI data on these joints. 8- 12 MRI definitions of important RA joint pathologies and a core set of basic.
