Abstract
Eautograph is an imaging technique refers to the measurement of elastic
properties of the tissue based on the well established principle that malignant tissue is harder than normal and benign tissues,it measures the relative stiffness of lesions in contrast to the surrounding normal tissue; the information displayed in the images is surrogate for that obtained with manual palpation. The technique is typically performed with ultrasound, but researches with magnetic resonance imaging are also
goind. Elastography is performed in the same session of ultrasound taking,color coded images is the most applicable method where images are displayed on the screen superimposed on the normal B-mode ultrasound image. Elastography has been performed as a complementary examination to the conventional US examination assessed by the BIRADs scoring system and not as a separate examination. The aim of this study was to evaluate the role of elastography and
mammography in diagnosis of breast masses.In this study we included 30 patients with different breast lesions. All patients had underwent into mammographic examination, conventional B-mode ultrasound examination and were evaluated according to the BIRADS categories, then real time free hand ultrasound elastography was performed in the same session and images were evaluated using both the Tsukuba elasticity score and the strain ratio method. Finally, the results were compared to the histo-pathological results of those lesions. Except for the case of simple cyst where there was no histopatholgy was taken and the patient was on follow u The results of this work were 10 histopathologicaly proven benign lesions and
20 histopathologicaly proven malignant lesions,in comparison to 8 benignelastographic looking lesions and 22 malignant elastographic looking lesions
