| 摘要 目的 探讨超声造影对周围型肺局灶性病变良恶性鉴别的临床意义。方法 回顾性分析116个周围型肺局灶性病变，其中良性病灶组62个，恶性病灶组54个。观察病灶超声造影的增强时相(ΔT<2.5s为早期增强、ΔT≥2.5s为晚期增强)及造影模式，对比分析良性病灶组与恶性病灶组的差别及诊断效率。结果 增强时相良性病灶组以早期增强为主，恶性病灶组以晚期增强为主，分别占比82.3%、64.8%，良恶性病灶差异有统计学意义(P<0.05)。造影模式良性病灶组以迅速基底树枝样增强为其特征，恶性病灶组以点片样增强为其特征，良恶性病灶差异有统计学意义(P<0.05)。分别以早期增强、迅速基底树枝样增强作为判断良性病灶指标，其敏感性、特异性、准确性分别为(82.3%，22.6%)、(66.7%，94.4%)、(75.0%，56.0%)；分别以晚期增强、点片样增强作为判断恶性病灶指标，其敏感性、特异性、准确性分别为(64.8%，68.5%)、(85.5%，62.9%)、(75.9%，65.5%)。结论 超声造影在周围型肺局灶性病变的鉴别诊断中有较高的临床价值。 |

| ?Abstract Purpose To explore the clinical significance of contrast enhancement characteristics of contrast-enhanced ultrasound in the diagnosis of focal peripheral lung lesions. Methods 116 peripheral pulmonary lesions were retrospectively analyzed, including 62 benign lesions and 54 malignant lesions. Lesions ultrasonic imaging enhancement phase (Δ T < 2.5s for early enhancement, Δ T≥ 2.5s for late enhancement ) and the enhancement patterns were recorded, and the difference between benign and malignant lesion group was compared, and then the diagnosis efficiency was analyzed. Results In the benign lesion group, early enhancement was dominant, while in the malignant lesion group, late enhancement was dominant, accounting for 82.3% and 64.8%, respectively, there was a statistically significant difference between benign and malignant lesions in the enhancement phase (P<0.05). In enhancement mode, the benign lesion group was characterized by Rapid basement dendrite enhancement, while the malignant lesion group was characterized by Dot chip enhancement, the difference between benign and malignant lesions was statistically significant (P<0.05). Early enhancement and Rapid basement dendrite enhancement were used as indicators to judge benign lesions, with sensitivity, specificity and accuracy (82.3%, 22.6%), (66.7%, 94.4%) and (75.0%, 56.0%), respectively. Late enhancement and Dot chip enhancement were used as the indicators of malignant lesions, respectively, and their sensitivity, specificity and accuracy were (64.8%, 68.5%), (85.5%, 62.9%), (75.9%, 65.5%), respectively. Conclusion contrast-enhanced ultrasound is of high clinical value in the differential diagnosis of focal benign and malignant lesions of peripheral lung. |
