目的:探讨双源CT双能量肺灌注显像在肺肿瘤的临床应用价值。方法:对23例肺占位性病变患者行双源CT双能量肺灌注成像。对比分析肿瘤与正常肺组织的能量灌注显像。结果:23例肿瘤患者肺肿瘤区域均出现灌注异常。结论:双源CT双能量肺灌注显像是一种全新的评价肺部肿瘤血流灌注状态的方法,但不具有特异性。对临床治疗有一定指导意义。
Objective: To investigate the clinical value of dual-source CT dual-energy lung perfusion imaging in lung cancer. Methods: Twenty-three patients with lung space-occupying lesions underwent dual-source CT dual-energy lung perfusion imaging. Comparative analysis of tumor and normal lung tissue by energy perfusion imaging. Results: Twenty-three cases of lung cancer patients showed abnormal perfusion. Conclusion: Dual-source CT dual-energy lung perfusion imaging is a new method to evaluate the perfusion of pulmonary tumors, but it is not specific. The clinical treatment of a certain significance.
