clarify the diagnostic efficiency of histogram and mean in tumor detection, this
study aims to compare the efficiency of mean and histogram metrics (i.e.
skewness, kurtosis, median, variance, entropy and energy) of Ktrans and kep at transverse slice with tumor biggest diameter in
discriminating benign lesion, grade II- and III-invasive ductal carcinomas
(IDC). The results indicate that in breast DCE-MRI, both mean and
histogram-metrics provide roughly comparable values in identifying malignancy
from benignancy. However, histogram-metrics are considerably more informative
and enable to discriminate pathological grade of IDCs. kep presented
better diagnostic efficiency than Ktrans.
