Sonoelastography (SE) is a new ultrasound technique currently used for the evaluation and characterization of soft tissue lesions. Generally,
the literature reports a superior stiffness of malignant lesions with respect to benign alterations of breast,
parotid and lymph nodes.Few studies focused on SE features of musculoskeletal lesions. The majority of previous studies for differentiating benign from malignant lesions adopted qualitative scales for evaluation of...
Methods and Materials
Prospective study Institutional review board approval and informed consent study were obtained Population study: 28 patients with superficial soft tissue lesions Examination: - gray-scale ultrasonography (US) - color and/or power doppler - sonoelastography in compression and decompression phase (My Lab 70 XVG system-Esaote-multifrequency trasducer 5-12 MHz) The strain data are represented as color-scale image and superimposed onto the relative B-mode image. Conventionally,
hard areas are...
Patient population In our study population 14/28 lesions were malignant and 14/28 lesions (50%) were benign. In the qualitative analysis : Malignant lesions: (Fig.
4,5,6,7) 14/14: score 4-5 Benign lesions: (Fig.8,9,10) 10/14: score 1-2 4/14: score 3 In the quantitative analysis (post-processing) : differences between median values in compression and decompression phase anddifferences betweenfraction area were different in blue,red and green color: Blue statistically significant correlation...
Preliminary results showed a good correlation between SE and reference standard. SE demonstrated all malignant lesions as hard lesions (increased stiffness),
confirmed by increasing of dark color in the qualitative analysis and increasing of values of blue in terms of median and fraction area in the selected ROI. The differentiation of benign tissue from malignant tumour is sometimes difficult with conventional US techniques,
color and/or power-Doppler add information about vascular pattern...
