摘要 目的探讨实时超声造影增强模式对肾上腺良恶性肿瘤的鉴别诊断价值。方法57个肾上腺病灶(恶性26个,良性31个)行常规超声及超声造影检查,重点观察病灶的造影增强模式。结果正常肾上腺超声造影表现为均匀、离心性和快速的髓质至皮质的增强。肾上腺良、恶性肿瘤超声造影的4项增强模式差异均有统计学意义(P〈0.05);以早期动脉相和动脉相相对增强并快速廓清诊断肾上腺恶性肿瘤的敏感性和特异性分别为96.2%和77.4%;以周边向中心向心性增强诊断恶性病灶的敏感性和特异性分别为76.9%和80.7%。结论实时超声造影增强模式有助于肾上腺肿瘤的良恶性评估。 Objective To explore the value of real time contrast-enhanced ultrasound (CEUS) in differential diagnosis of benign and malignant adrenal lesions. Methods Totally, 57 adrenal lesions (25 malignant and 31 benign) underwent conventional ultrasound and real-time CEUS. The enhancement patterns including types of time-intensity curve, centripetal fill-in, homogeneity and intensity of enhancement were analyzed. Results The enhancement pattern of normal adrenal gland was homogeneous,centrifugal and rapid perfusion from the medulla to the cortex. Four enhancement patterns were significantly different between benign and malignant adrenal lesions ( P 〈0.05). If enhancement in the early arterial phase and rapid washout was suggestive of malignancy, the sensitivity and specificity of CEUS were 96.2% and 77.4%,respectively. If peripheral to central filling was suggestive of malignancy, the sensitivity and specificity of CEUS were 76.9% and 80.7% ,respectively. Conclusions The patterns of real-time CEUS are helpful in differential diagnosis of malignant and benign adrenal lesions.
