Abstract

The variance of manually tracing organ boundaries from magnetic resonance images (MRIs) was investigated. Two operators traced 10 times seven organs from MRIs acquired at the end systole and diastole. It is shown that the coefficient of variation (CV) correlates inversely with the organ area except for the ventricles. The largest CV was 17% for descending aorta at end diastole and the smallest was 1% for right lung with an average of 6%.
