Abstract:
The contrast substances have been used in the magnetic resonance imaging (MRI) to increase the sensitivity and specificity of diagnosis. It impacts on the density of proton and spin-spin time (T1 and T2). There were many different substances studied to increase the density of proton such as water, alcohol, hydrocarbon, and sugar or perfluoroctyl bromide. However, only paramagnetic compounds impacts on the spin-spin time were studied much and are being used.
