肝脏肿瘤多层螺旋CT与MRI影像学特点及鉴别价值比较

Comparison of the Imaging Characteristics and Value of Multi-slice Spiral CT and MRI of Liver Tumor

目的分析多层螺旋CT与MRI在肝脏肿瘤临床诊断中的应用价值。方法收集我院自2013年4月-2015年4月收治的60例经病理证实为肝脏肿瘤患者的临床资料,分别作多层螺旋CT及MRI检查,总结肝脏肿瘤的影像学特点,分析多层螺旋CT及MRI在肝脏肿瘤鉴别诊断中的应用价值。结果 60例肝脏肿瘤患者增强CT动脉期检出病灶68个,其中高密度病灶28个,低密度病灶8个,等密度10个;门静脉期共检出病灶40个,其中低密度病灶22个,4例患者CT平扫未见异常表现,MRI检查T2WI序列提示存在异常信号,增强扫描后病灶显示清晰。结论多层螺旋CT与MRI扫描,可充分反映肝脏肿瘤的血供特点,提高肝脏肿瘤的检出率,同时两者联合可为肝脏肿瘤的鉴别诊断提供可靠依据,值得推广。

Objective To analyze the application value of multi-slice spiral CT and MRI in the clinical diagnosis of liver tumor. Methods The clinical data of 60 patients pathologically confirmed with liver tumor and admitted into the hospital from April 2013 to April 2015 were collected. They respectively received multi-slice spiral CT and MRI scan. The imaging features of liver tumors were summarized and the application value of multi-slice spiral CT and MRI in the differential diagnosis of liver tumors were analyzed. Results Among the 60 cases of patients with liver tumors, there were 68 lesions detected in arterial phase, of which there were 28 high-density lesions, 8 low-density lesions and 10 equidensity lesions. There were 40 lesions detected in portal venous phase which included 22 low density lesions. There were 4 cases of patients with CT plain scan showed no abnormal findings. MRI test showed that T2 WI sequence suggested the presence of abnormal signals. After enhanced scanning, lesions were displayed clearly. Conclusion Multi-slice spiral CT and MRI scan can fully reflect the blood supply of hepatic tumor, and improve the detection rate. The combination of both methods can provide reliable basis for the differential diagnosis of liver tumors, which is worthy to be popularized.
