Systematic analysis and application of magnetic resonance imaging

During medical technology development in recent year, The MRI (magnetic resonance imaging) technology get a wide range of application in different hospital to check issues in human’s body. In this article will mention two different types of relaxation time to explain which factors can influence relaxation time and to discuss about how does different relaxation time effect imaging quality in MRI. In this part, I will give specific examples of internal and external environmental factors that affect relaxation time. I will discuss how different speeds of relaxation time affect the quality of MRI imaging through three medical staff experiment. After analysing three studies, it was concluded that T1 relaxation time was longer in normal brain tissue and shorter in malignant tumours than in benign tumours and normal brain tissue and T1rho relaxation times were prolonged in cartilage regions affected by osteoarthritis, reflecting changes in calcium content and collagen integrity in bone. The significance of this paper is to point out the influence of relaxation time on MRI image quality, and advocate more cooperation between scholars in different fields to make MRI technology more mature, so as to better help doctors treat patient.
