MRI has greatly improved diagnostic medicine in recent decades. By constantly changing and improving
technological aspects, MRI is becoming an increasingly sophisticated and refined method. By constantly
tending to increase the used magnetic field, the spatial resolution and contrast increase due to the increase
in SNR. These factors enable a detailed and clear presentation of previously invisible pathologies, especially
pathologies in the brain. The aim of this work is to compare the importance of the technological features
of 3T and 7T MRI in brain imaging and to distinguish their advantages and disadvantages. 3T MRI is used
in daily clinical practice worldwide. One of the basic questions that scientists deal with in most research
is the importance of 7T compared to 3T in the presentation of various brain pathologies. It was found that
the improved technological characteristics of the device with a higher magnetic field affect the better
representation of epileptogenic lesions and lesions that are specific for multiple sclerosis. In addition, a better
representation of the internal structure of the tumor, a better representation of aneurysms and microbleeds
and changes that are characteristic of neurodegenerative diseases such as Alzheimer’s disease and
Parkinson’s disease is obtained. It was of great importance to determine whether there is superiority of 7T in
these pathologies to determine all the available possibilities, advantages and disadvantages because these
are diseases that have an increasing prevalence in the population. On the 7T MRI, there are also technological
problems that can lead to poor recording quality, for which various solutions are proposed and investigated.
After reviewing numerous studies, it was determined that 3T MRI is a quality device for current use, but 7T
has the ability to display details and can provide a higher quality image and greater diagnostic precision and
can be of great importance, especially in certain patients where 3T is not detailed enough. It should be noted
that 7T MRI still needs to be researched, but it is safe for human use and represents the future of diagnostic
