【摘要】：肝癌作为世界上最常见的恶性肿瘤之一，通常被发现的时候已是晚期，其中原发性肝癌小病灶更为特殊，因其体积小、血液供应情况不良、患者症状不明显等因素而在肝癌中更难被常规检查所发现;其中CT是常规的扫描方法，尤其是螺旋CT增强扫描，能很大程度上弥补了常规CT扫描检查的不足。Dyna-CT可提高对肝癌小病灶的检出率，并能更清晰的提供肝肿瘤供血血管的解剖信息，对原发性肝癌小病灶及微小病灶的诊断和治疗提供了更可靠的信息。本文将2011年6月至2012年6月吉林大学第一医院介入治疗科收入院，行TACE（TranshepaticArterial ChemotherapyAnd Embolization肝动脉化疗栓塞术）术且术中接受Dyna-CT检查的患者为研究对象，，入选患者按照病灶大小分为三组：A组病灶直径≤1.0cm，B组病灶直径1.1-2.0cm，C组病灶直径2.1-3.0cm。均常规行螺旋CT三期增强扫描，并行TACE术，并在介入治疗手术中行Dyna-CT扫描，比较患者行螺旋CT增强扫描及Dyna-CT扫描检出肝癌结节的数目，并进行统计学分析，探讨Dyna-CT在原发性肝癌临床诊断中的应用价值及其对TACE术的指导价值。
[Abstract]:As one of the most common malignant tumors in the world, liver cancer is usually found at the late stage, in which the small focus of primary liver cancer is more special, because of its small size and poor blood supply. The symptoms of the patients were not obvious and it was more difficult to find them in liver cancer by routine examination. Ct is a conventional scanning method, especially spiral CT enhanced scan, which can make up for the deficiency of conventional CT scanning. Dyna-CT can improve the detection rate of small focus of liver cancer. And can provide more clearly the anatomical information of blood supply vessel of liver tumor. It provides more reliable information for the diagnosis and treatment of small focus and small focus of primary liver cancer. From June 2011 to June 2012, the department of interventional therapy in the first Hospital of Jilin University was admitted to the hospital. TACE(TranshepaticArterial ChemotherapyAnd Embolization hepatic artery chemoembolization. Patients who underwent Dyna-CT during operation were studied. The patients were divided into three groups according to the size of the lesions. The diameter of lesions in group A was less than 1.0 cm. The diameter of lesions in group B was 1.1-2.0 cm. The lesion diameters of group C were 2.1-3.0 cm. All patients were performed spiral CT three-phase enhanced scan, followed by TACE, and Dyna-CT scan was performed during interventional therapy. The number of HCC nodules detected by spiral CT enhanced scan and Dyna-CT scan were compared and statistically analyzed. To explore the value of Dyna-CT in the clinical diagnosis of primary liver cancer and its guiding value in TACE operation.
