Abstract:
In recent years,with the continuous advancement of MRI technology,5.0T MRI has gradually become a focal point of interest in both clinical and research fields.Compared with traditional 1.5T and 3.0T systems,the signal-to-noise ratio on the 5.0T platform increases superlinearly,while certain tissue properties such as T1 values,T2(T2*)values change,making chemical shift phenomena and susceptibility effects more pronounced.This brings new application prospects for fat suppression,magnetic resonance spectroscopy and functional imaging techniques.Despite the challenges that the 5.0T system faces in terms of main magnetic field(B0)uniformity,radiofrequency field(B1)distribution and specific absorption rate control,these issues have been effectively mitigated through hardware innovation,sequence optimization and intelligent control technologies.The system shows significant advantages in conventional and functional imaging in areas such as the nervous system,bone joints,cardiovascular and cerebrovascular,and abdominal regions.This article discusses the technological breakthroughs,clinical application potential and future challenges of 5.0T MRI technology based on the latest research progress.
