| 摘要 目的：探究CT联合MRI在早期肝癌诊断中的应用价值。方法：选择2016年6月至2019年6月于我院接受诊断治疗的78例已知或疑似肝癌患者，分别对其实施CT及MRI检测，以病灶部位病理学检查结果为金标准（50例确诊为早期肝癌，28例为良性病变），分别评估CT、MRI、CT联合MRI对早期肝癌的诊断价值，将确诊为肝癌的50例患者按照病灶大小区分为直径≤3 cm组（21例）和>3 cm组（29例），对比CT与MRI对不同直径肝癌诊断率。结果：（1）检测发现，CT对早期肝癌诊断一致性为73.08 %，灵敏度为72.00 %，特异度为75.00 %；（2）MRI对早期肝癌诊断一致性为82.05 %，灵敏度为82.00 %，特异度为82.14 %；（3）CT联合MRI检测对早期肝癌诊断一致性为93.59 %，灵敏度为92.00 %，特异度为96.43 %；（4）对比发现，对直径≤3 cm的早期肝癌患者，MRI诊断率明显高于CT（95.24 % vs 76.19 %，P<0.05）。结论：CT及MRI对早期肝癌均具有较好的诊断价值，但联合检测明显优于任一单独检测，同时对病灶直径≤3 cm的早期肝癌患者，MRI诊断准确率更高。 |

| ABSTRACT Objective: To explore the value of CT combined with MRI in the diagnosis of early liver cancer. Methods: A total of 78 patients with known or suspected liver cancer who were diagnosed and treated in our hospital from June 2016 to June 2019 were enrolled in the study. CT and MRI were performed on the patients. The pathological findings of the lesions were based on the gold standard (50 cases of early liver cancer, 28 cases of benign lesions). The diagnostic value of CT, MRI, CT combined with MRI in early liver cancer was evaluated. 50 patients diagnosed as liver cancer were divided into diameter ≤3 cm(21 cases) and >3 cm group (29 cases) according to lesion size, comparing the CT and MRI for the diagnosis rate of different diameters. Results: (1) The detection showed that the consistency of CT diagnosis of early liver cancer was 73.08 %, the sensitivity was 72.00 %, and the specificity was 75.00 %; (2) The consistency of MRI diagnosis of early liver cancer was 82.05 %, and the sensitivity was 82.00 %. The degree of diagnosis was 82.14 %; (3) CT combined with MRI showed a consistency of diagnosis of early liver cancer was 93.59 %, the sensitivity was 92.00 %, and the specificity was 96.43 %; (4) Contrast found that the diagnosis rate of MRI was obvious for early liver cancer patients with diameter ≤3 cm was significantly higher than that of CT(95.24% vs 76.19%, P<0.05). Conclusion: CT and MRI have good diagnostic value for early liver cancer, but the combined detection is better than any single detection. At the same time, the accuracy of MRI diagnosis is higher for early stage liver cancer patients with lesion diameter ≤3 cm. |
