ABSTRACT
Objective To investigate the consistency in the measurement of epicardial adipose tissue (EAT)volume using non-ECG-gated CT and ECG-gated CT.Methods ECG-gated CT and non-ECG-gated CT examinations were obtained in 104 subjects. The ECG-gated group was outlined the epicardium by an associate chief physician with a hand-painted method,the CT value of quan-titative adipose tissue was ranged from -30 HU to -250 HU.The non-ECG-gated group was outlined the epicardium by two asso-ciate chief physicians,A and B;The two CT values were ranged from -20 HU to -250 HU and from -30 HU to -250 HU,re-spectively.The measurement results of two groups were compared for the analysis of the relationship between EAT volume and cor-onary atherosclerosis.Results After the employment of CT value ranging from -20 HU to -250 HU for non-ECG-gated group, the measurement result was well consistent with ECG-gated group.The measurement results obtained by two associate chief physi-cians using the same range of CT value were in a good consistency.The EAT volumes obtained by various measurements were all correlated to the occurrence of coronary atherosclerosis.Conclusion After adjusting the range of CT value,two methods were in a good consistency.Non-ECG-gated CT measurement of EAT volume is easy to operate,which has a better practical value.
