5). 4 Signal intensity and T1 relaxation time. 5 Signal intensity and T2 relaxation time. 38 Intravascular contrast media show that, for a given time t, if the T1 relaxation is more rapid then a larger signal is obtained (brighter images), but the opposite is true for T2 relaxation, where more rapid relaxation produces reduced signal intensity (darker images). There are different means by which these effects on protons can be produced using a range of MRI contrast agents. MRI contrast agents must exert a large magnetic field density (a property imparted by their unpaired electrons) to interact with the magnetic moments of the protons in the tissues and so shorten their T1 relaxation time, which will produce an increase in signal intensity (see Fig.

Radiology 2010;256(3):744–50. 2 CONTRAST AGENTS IN MAGNETIC RESONANCE IMAGING HISTORICAL DEVELOPMENT Shortly after the introduction of clinical MRI, the first contrastenhanced human MRI studies were reported in 1981 using ferric chloride as a contrast agent in the gastrointestinal tract. In 1984, Carr et al. 1 Currently, around one-quarter of all MRI examinations are performed with contrast agents. 37 Guide to radiological procedures MECHANISM OF ACTION Signal intensity Whilst radiographic contrast agents use a direct alteration in tissue density to allow the visualization of structures, the MRI contrast agents act indirectly by altering the magnetic properties of hydrogen ions (protons) in water and lipid which form the basis of the image in MRI.
