目的:探讨肝癌患者的电子计算机X射线断层扫描(CT)检查表现,总结影像学特征,从而为临床诊治提供依据。方法:选取肝癌患者60例进行分析,均采用全身CT扫描仪进行检查,观察患者的CT检查分型情况和表现,总结CT影像学特征。结果:60例患者肝癌的CT检查准确率达到100%,分型以巨块型为主(71.7%),其次为结节型(26.7%)和弥漫型(6.6%)。不同分型的肝癌CT表现各有差异,其中弥漫型没有发生中心坏死,结节型以低密度(69.2%)表现为主,巨块型以低密度(95.3%)和腹膜后移(48.9%)为主。平扫结果显示大部分病灶密度较低,少数呈现出血或钙化,部分合并淋巴结转移和癌栓;增强扫描显示病灶内部血供丰富,大部分边界清晰,内部出现小结节或分隔,不均匀强化。结论:对于肝癌患者而言,CT扫描检查具有较高的准确性,能够呈现出不同的肝癌分型和表现,且影像学特征各有差异。掌握这些特征,对于患者的临床诊断和预后效果具有重要的应用价值。
Objective: To investigate the computerized tomography (CT) examination of liver cancer patients and summarize the imaging features so as to provide the basis for clinical diagnosis and treatment. Methods: Totally 60 patients with hepatocellular carcinoma were selected for analysis. All of them were examined by whole-body CT scanner. The CT findings and classification of the patients were observed. The features of CT imaging were summarized. Results: The accuracy of CT examination of liver cancer in 100 patients was 100%. The majority of them were giant type (71.7%), followed by nodules (26.7%) and diffuse type (6.6%). The CT findings of different types of liver cancer were different, including diffuse type without central necrosis, nodular low density (69.2%), low mass density (95.3%) and retroperitoneal (48.9% ) Based. The results of plain scan showed that most of the lesions had lower density, a few of them presented with hemorrhage or calcification, some were accompanied with lymph node metastasis and thrombus. Enhanced scanning showed abundant blood supply inside the lesion, most of the border was clear, internal nodules or separation, uneven enhancement . Conclusion: For patients with liver cancer, CT scan examination with high accuracy, can show a different type and performance of liver cancer, and the imaging features are different. Grasp these characteristics, for the clinical diagnosis and prognosis of patients with important application value.
