摘要
目的探讨超声造影对肝脏囊实性病变的诊断价值。方法对经病理或穿刺活检证实的35例肝脏囊实性病变患者39个病灶(25个良性病灶,14个恶性病灶)的常规灰阶超声及超声造影表现进行回顾性分析。结果超声造影表现为:恶性病变100%(14/14)呈动脉期高增强,门脉期退出呈低增强,延迟期退出更加明显。常规灰阶超声对恶性肝脏囊实性病变诊断的敏感度为71.4%(10/14)、特异度为96.0%(24/25)、准确性为87.2%(34/39);超声造影对恶性肝脏囊实性病变诊断的敏感度为100%(14/14)、特异度为92.0%(23/25)、准确性为94.9%(37/39)。结论超声造影检查有利于肝脏囊实性病变的定性诊断,可为临床选择治疗方式提供帮助及依据。
Objective To evaluate the value of contrast-enhanced ultrasonography (CEUS) in diagnosis of liver cystic-solid lesions.Methods The features of conventional gray scales and contrast-enhanced ultrasonography(CEUS) for the 35 patients with cystic-solid lesions of the liver(39 lesions:benign 25, malignant 14) proved by pathology or biopsy were analyzed. Results CEUS:The malignant lesions assumed 100%(14/14) hyper-enhancement in the arterial phase, hypo-enhancement in the portal phases and withdrawal was more obvious in the late phases. The sensitivity, specificity, and accuracy of the conventional gray scales for the malignant cystic-solid lesions were 71.4%(10/14), 96.0%(24/25),and 87.1%(34/39), respectively,while the CEUS were 100%(14/14), 92.0%(23/25), and 94.8%(37/39), respectively. Conclusion CEUS is more effective in qualitative diagnosis of the liver cystic-solid lesions, providing the utility and the basis for the clinical treatment.
