Abstract: 【Objective】 The purpose of this study was to discuss the diagnosis value of IDEAL-IQ sequence to hepatic steatosis and hepatic iron overload in the patients. 【Methods】 20 patients with fatty liver (fatty liver group)

20 cases of thalassemia patients with repeated blood transfusion (anemia group)

20 healthy subjects (control group) were obtained using IDEAL-IQ sequence on a 3.0T scanner. Fat ratio image

R2* relaxation rate image were used to diagnosis whether there is hepatic steatosis or hepatic iron overload. 【Results】 The fat content of fatty liver group and control group were 15.28±5.75% and 3.45±1.81%

respectively. Statistically significant difference was obtained. The R2* value of anemia group and control group were 592.15±115.31Hz and 36.56±14.6Hz

respectively. There was obviously statistical difference between them. In addition

the fat content of 2 patients in anemia group were 15% and 45% respectively. 【Conclusion】 There were several group images once IDEAL-IQ sequence was scanned

fat ratio image

R2* relaxation rate image could be used to quantitative diagnosis hepatic steatosis and hepatic iron-overloaded

there was important clinical value for the diagnosis of hepatic steatosis in the hepatic iron-overloaded patients.
