Due to the isoechoic nature of lesions and their poor contrast with neighbouring tissue, a lesion may remain
undetected in ultrasound B mode imaging for cancerous tissue. Imaging of the elastic properties of tissue provides new
information which is collateral to tissue pathology. This study provides quantitative analysis of improvements in tumour
diagnosis when the ultrasound B mode imaging is combined with elastography. Quantification was based on the textural
parameters measured from the ultrasound B mode image and strain measured from the elastogram. The ability of a
parameter to discriminate between diseased cases and normal cases was evaluated using receiver operating characteristic
(ROC) analysis. Polyacrylamide gel based tissue mimicking phantoms with embedded inclusions of varying stiffness
were used for the analysis.
