超声弹性成像在表浅软组织良恶性肿块鉴别诊断中的价值

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

目的 探讨超声弹性成像对于表浅软组织良恶性肿块患者的临床诊断价值。方法 对96例表浅软组织良恶性肿块患者进行弹性成像检测,并将诊断结果与病理检查结果进行对比分析。结果 96例患者共有肿块134个,病理检查确诊为良性肿块92个,恶性肿块42个。弹性图分级0级有6个肿块,均为良性肿块;1级有21个肿块,也均为良性肿块;2级有59个肿块,良性肿块53个,恶性肿块6个;3级有37个肿块,良性肿块9个,恶性肿块28个;4级有11个肿块,良性肿块3个,恶性肿块8个。2种检查结果比较可以发现,良性肿块多集中于0~2级,而恶性肿块多集中于3~4级,良性肿块和恶性肿块的弹性分级比较差异有统计学意义（P〈0.05）。按照弹性成像分级3级为恶性肿块与良性肿块的分界点,采用超声弹性成像技术对浅表软组织肿块患者的恶性与良性肿块诊断的准确率为86.6%（116/134）。结论 弹性成像作为一项新兴检测技术,其对表浅软组织良恶性肿块的检出率较高。

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.
