Chronic liver disease causes iron deposition such as liver cirrhosis.Because iron is paramagnetic, when iron deposition increases, the uniformity of the local magnetic field changes to various degrees depending on the content of the iron deposition. Thus, iron deposition can result in an increase in susceptibility effects, thereby affecting the T2∗relaxation time and R2* value.Resently, a novel MRI sequence, enhanced susceptibility weighted angiography (ESWAN), has been widely used in clinical practice .The aim of this study was to investigate the interrelation between hepatic Iron deposition and liver function in patients with liver cirrhosis by means of enhanced T2 star-weighted angiography (ESWAN).
