摘　　要：肝脏局灶性病变的定性诊断对于肝癌早期诊断、术前准确分期、血流灌注的评价以及治疗方案的确定具有重要意义,因此也是临床研究的难点。各种成像技术的增强检查对肝脏局灶性病变的诊断均具有较高的敏感性和特异性,临床上常规应用方法包括增强CT、增强MRI、增强超声等,了解不同方法的优缺点,合理选择,必要时联合应用,可提高诊断准确性。Qualitative diagnosis of focal liver lesions is challenging in clinical situation, especially for early diagnosis of hepatocellular carcinoma. Precious preoperative staging in the liver cancer and accurate evaluating the perfusion of focal liver lesions are important for the treatment planning. Contrast-enhanced tomography has high sensitivity and specificity in the diagnosis of focal liver lesions. Nowadays, commonly used tools are contrast-enhanced CT, contrast-enhanced MRI, and contrast-enhanced ultrasound, etc. Understanding the advantages and disadvantages of each examination would be useful for choosing combined examinations to improve diagnostic accuracy.
