摘　　要：目的探究原发性脑内恶性淋巴瘤应用CT与MRI联合诊断诊断价值。方法以2016年5月至2019年5月期间我院收治43例疑似原发性脑内恶性淋巴瘤患者为对象,两组患者均接受CT与MRI检查,随后采用活检或者手术方式进一步确定患者病情。比较CT、MRI、CT联合MRI诊断原发性恶性淋巴瘤符合率、病灶位置情况,诊断价值。结果活检与手术病理结果显示43例患者中原发性恶性淋巴瘤40例,CT诊断原发性恶性淋巴瘤符合率为80.0%(32/40),MRI诊断符合率为87.5%(35/40),CT联合MRI诊断符合率100%(40/40),仅联合诊断符合率与CT诊断差异具有统计学意义(χ2=8.889,P<0.05);CT联合MRI对病灶位置情况诊断准确率高于单用CT与MRI,仅联合方式与CT之间诊断准确率差异具有统计学意义(P<0.05);CT联合MRI诊断原发性脑内恶性淋巴瘤灵敏度、特异度以及准确度均高于单用CT与MRI诊断。结论原发性脑内恶性淋巴瘤诊断联合应用CT与MRI能够有效提高诊断价值,临床应用价值优异。Objective To explore diagnostic value of CT combined with MRI for primary cerebral malignant lymphoma.Methods 43 patients with suspected with primary cerebral malignant lymphoma who were admitted to the hospital from May 2016 to May 2019 were enrolled.Both groups underwent CT and MRI.Then,biopsy or surgery was given to further confirmed conditions of patients.The diagnostic coincidence rate of CT,MRI and CT combined with MRI for primary malignant lymphoma,lesion positions and their diagnostic value were compared.Results Biopsy and surgical pathology results showed there were 40 cases with primary malignant lymphoma in 43 patients.The diagnostic coincidence rates of CT,MRI and CT combined with MRI for primary malignant lymphoma were 80.0%(32/40),87.5%(35/40)and 100%(40/40),respectively.There were significant differences in coincidence rate only between combination diagnostic and CT diagnosis(χ2=8.889,P<0.05).The diagnostic accuracy of CT combined with MRI for lesions positions were higher than that of CT and MRI alone.There were significant differences in diagnostic accuracy only between combination mode and CT(P<0.05).The sensitivity,specificity and accuracy of CT combined with MRI for diagnosis of primary cerebral malignant lymphoma were higher than those of CT and MRI alone.Conclusion The application of CT combined with MRI in diagnosis of primary cerebral malignant lymphoma can effectively improve diagnostic value,and clinical application value is excellent.
