摘要/Abstract

摘要：

目的分析超声造影检查对下颌骨良性病变的诊断能力。方法选择经病理检查证实为下颌骨良性病损的患者,回顾其超声造影检查,观察病损的位置、大小、边界及内部回声的特征、血流分布情况、造影增强信号强度等,结合CBCT进行比较分析。结果病理证实牙源性角化囊性瘤7例、成釉细胞瘤6例、颌骨囊肿4例、骨化纤维瘤2例、牙源性黏液瘤1例、脉管畸形1例、朗格汉斯组织细胞增生症1例。超声造影均能以无回声至低回声对上述病变进行显示,造影结果证实所有含有实性成分的病灶内均有明显在增强。相比于CBCT,超声造影依赖回声均匀度、血流信号及造影后增强信号可对部分的囊实性病变作出判断。结论与CBCT相比,超声造影检查除了能够清晰显示颌骨内病灶边界外还能够显示病灶内软组织内容物和血流情况,提供更多的诊断信息。

Abstract:

Objective To analyze the diagnostic ability of contrast-enhanced ultrasonography in benign lesions of the mandibular bone. Methods Patients with benign mandibular lesions confirmed by pathological examination were selected, and the location, size, boundary and internal echo characteristics, blood flow distribution, contrast-enhanced signal intensity, etc. of the lesion were observed by contrast-enhanced ultrasound(CEUS), and were compared with CBCT. Results Seven cases ofodontogenickeratocystic tumor, 6 cases of ameloblastoma, 4 cases of jaw cyst, 2 cases of ossifying fibroma, one case of odontogenicmyxoma, one case of vascular malformation and one case of Langerhans histiocytosis were pathologically confirmed. Contrast-enhanced ultrasound could display the lesions mentioned above with anechoic to hypoechoic, and contrast-enhanced results confirmed that all lesions with solid components were significantly enhanced. Compared with CBCT, CEUS relied on echo uniformity, blood flow signal and post-contrast enhancement signal to verify partial cystic solidity. Conclusion Compared with CBCT, contrast-enhanced ultrasonography can displaynot only the boundary of lesions in the jaw, but also the soft tissue content and blood flow in the lesion, and provide more diagnostic information.
