Value of ultrasound elastography in the differential diagnosis of benign and malignant masses in superficial soft tissue

Objective To study the diagnostic value of ultrasound elastography in benign and malignant tumors of superficial soft tissue. Methods Ninety-six patients with superficial soft tissue masses were experienced elastic imaging detection,then the diagnosis results were compared with pathological results. Results The pathology examination results of 96 patients( 134 masses) showed that 92 masses were benign,42 masses were malignant tumor. Elastic graph class results showed that 6 masses was grade 0,which were benign lesions; 21 masses were grade 1,which were benign lesions; 59 masses were grade 2( 6 malignant tumor,53 benign lesions); 37 masses were grade 3( 28 malignant tumor,9 benign lesions); 11 masses were grade 4( 8 malignant tumor,3 benign lesions). Two kinds of examination results showed that benign masses more concentrated in the grade 0- 2,while malignant masses concentrated in grade 3- 4. There were statistic difference of elastic classification between benign masses and malignant masses( P 0. 05). Grade 3 was train spacing point of malignant masses and benign masses. The diagnosis accuracy rate of ultrasound elastography technique in patients with malignant and benign tumors of superficial soft tissue was 86. 6%( 116 /134). Conclusion Elastography is a newly developed detection technique,its detection rate in superficial benign and malignant soft tissue masses is higher.
