Strain histograms are equal to strain ratios in predicting malignancy in breast tumours
Fig 5
Diagrams showing the strain histogram and strain ratio values for all BI-RADS 3 tumours.
Note that strain histogram values (range 0–255) are unitless, and that strain ratios (range 0-∞) are also unitless and the y-axis is logarithmic. The dashed line on each diagram shows the cut-off used when combining strain histogram (cut-off = 189) or strain ratio (cut-off = 1.44) values with ultrasound BI-RADS scoring.
