The purpose of this review is to present the advantages (high SNR,
ASL) and disadvantages (Dielectric effect,
Chemical Shift artifact,
sequence Optimizatin) of high-field MRI,
as well as ways to overcome the disadvantages.
The rapid development of technology coupled with the further development of IT applications and their prevalence in an ever-increasing range of human activity has also catalytically affected the health sector,
creating new possibilities and prospects for medical applications.
the medical imaging sector has been one of the fields of medical science,
which has been influenced by the explosion of medical devices and products.
A characteristic example of this,
is the evolution of the MRI which became the “flagship” of Medical Imaging just within a...
Findings and procedure details
Although the first systems of the MRI Scanners are characterized by relatively low static magnetic fields as well as time-consuming and multidisciplinary data recovery procedures,
nowadays the trend is the use of high-field magnetic resonators,
namely MRI Scanners with a static field greater than or equal to 3.0 Tesla.
Specifically MRI systems equal to 3 T mainly used in everyday clinical practice,
were called to replace the 1.5 T ones which are the majority of the operating magnetic resonators,
at the level of clinical practice....
It is obvious that the use of high-field systems is not a one-way model in magnetic resonance imaging.
it excels in specialized applications,
1.5 Tesla systems also have significant advantages in features useful in routine MRI scanning sequences.
