Zhihong Hu,Xinwen Chen,Xiulian Sunecific means of characterizing disease processes which, although ultimately based on molecular derangements, manifest themselves on a micro- and macrostructural and functional level. Thus MRI techniques geared towards elucidating these pathophysiological processes had to be developed.

,Modified Big Bang–Big Crunch Algorithm, development of magnetic resonance angiography (MRA), EPI angiographic techniques may be used to obtain dramatic reductions in scan time that could permit rapid screening of large vascular territories and later assessment by higher resolution MRA techniques.

Postmortem Conditioning of Meat,ponds a different frequency at which the spins resonate. Thus frequency analysis of the NMR signal could provide an indication of how many spins are to be found at any particular plane in space, corresponding to a given contour of the magnetic field; in short, a . of the spin density in the object.

Advances in Medical Engineeringl developments have made the fulfilment of EPI’s technical requirements more straightforward, and the new generation of commercial MR scanners incorporate hardware improvements which will allow the routine implementation of EPI.
