探讨超声弹性成像对浅表软组织良恶性肿块的鉴别诊断价值

摘要

Objective To investigate the differential diagnosis value by ultrasonic elastography for benign and malignant mass in superficial soft tissue. Methods There were 68 patients receiving surgical treatment for superficial soft tissue mass, as totally 70 masses. They received ultrasonic elastography examination, and elasticity images were classified into 0,Ⅰ,Ⅱ,Ⅲ,Ⅳdegrees.Ⅲdegree was the critical standard of diagnosis between benign and malignant mass in superficial soft tissue. The differential result was combined with surgical pathology. Results Elastic classification of benign mass mainly in superficial soft tissue included 0~Ⅱdegree, and that of malignant mass included Ⅲ~Ⅳdegree. The difference of elastic classification between benign and malignant mass had statistical significance (P<0.05). Conclusion As a new evaluation method, ultrasonic elastography can provide high accuracy in identification of benign and malignant mass in superficial soft tissue, but there is still some overlap in classification standards of benign and malignant mass, and that is needed to be further improved.%目的：探讨超声弹性成像对浅表软组织良恶性肿块的鉴别诊断价值。方法68例经过手术治疗的浅表软组织肿块患者，共70个肿块。给予研究对象超声弹性成像检查，将弹性成像结果分为0、Ⅰ、Ⅱ、Ⅲ、Ⅳ共5级，其中Ⅲ级为浅表软组织良、恶性的诊断临界标准，并结合手术病理结果鉴别。结果体表软组织的良性肿块中以0~Ⅱ级弹性居多，体表软组织的恶性肿块中以Ⅲ~Ⅳ级弹性分级居多，良恶性肿块的弹性分级差异具有统计学意义(P<0.05)。结论超声弹性成像是对浅表软组织肿瘤的组织学特性的一种新兴评估手段，临床有助于鉴别浅表软组织肿块的良恶性，且准确率较高，但浅表软组织良恶性肿块的弹性分级标准仍存在部分重叠，有待加以改进。
