目的总结双能量CT扫描技术在肝脏方面的应用。方法查阅国内外相关文献,对双能量CT扫描技术在肝脏局灶性病变及肝脏弥漫性病变两方面的运用进行分析总结。结果双能量CT扫描技术可以提高肝脏局灶性病变及肝脏恶性肿瘤病变行局部治疗后复发灶的检出率,有助于肝脏局灶性病变的鉴别、恶性病变的分期,且可较准确地定量肝脏铁和脂肪的含量,间接测量肝脏的血流动力学改变情况。结论双能量CT扫描技术可以提高CT扫描技术对肝脏疾病的诊断价值。
Objective To summarize the application of dual-energy CT scanning in the liver. Methods The related literatures at home and abroad were consulted, and the application of dual-energy CT scanning technique in focal hepatic lesions and diffuse liver lesions were analyzed and summarized. Results Dual-energy CT scanning can improve the detection rate of focal liver lesions and liver malignancy after the local treatment of recurrent lesions, contribute to the identification of focal liver lesions, malignant lesions staging, and more accurately Quantitative liver iron and fat content, indirect measurement of hemodynamic changes in the liver. Conclusion Dual-energy CT scan can improve the diagnostic value of CT scanning in liver diseases.
