超声心动图检查在心脏良恶性肿瘤鉴别诊断中的应用价值

Application value of echocardiography examination in differential diagnosis of benign and malignant cardiac tumors

目的探讨超声心动图检查在心脏良恶性肿瘤鉴别诊断中的应用价值。方法将2018年1月至2020年10月于我院就诊的85例心脏肿瘤患者纳入研究,且均实施计算机断层扫描(CT)、磁共振成像(MRI)、超声心动图检查。以手术病理诊断结果为参照,比较CT、MRI、超声心动图检查对心脏良恶性肿瘤的鉴别诊断结果和诊断效能;分析CT、MRI、超声心动图检查与手术病理诊断结果之间的一致性;比较CT、MRI、超声心动图检查对心脏肿瘤定位诊断的符合率。结果 85例心脏肿瘤患者中,经手术病理诊断确诊54例为心脏恶性肿瘤(阳性),31例为心脏良性肿瘤(阴性)。以手术病理诊断结果为参照,MRI、超声心动图检查在心脏良恶性肿瘤鉴别诊断中的灵敏度、特异度、准确度、阳性预测值、阴性预测值均高于CT检查(P<0.05);而MRI检查与超声心动图检查的灵敏度、特异度、准确度、阳性预测值、阴性预测值比较,差异均无统计学意义(P>0.05)。在心脏良恶性肿瘤的鉴别诊断中,CT检查与手术病理诊断结果之间具有中度一致性;MRI、超声心动图检查与手术病理诊断结果之间具有高度一致性。MRI、超声心动图检查对左房、右房心脏肿瘤的诊断符合率均高于CT检查(P<0.05);MRI与超声心动图检查对左房、右房心脏肿瘤的诊断符合率比较,差异均无统计学意义(P>0.05);CT、MRI、超声心动图检查对右室心脏肿瘤的诊断符合率比较,差异均无统计学意义(P>0.05)。结论超声心动图检查可对心脏良恶性肿瘤进行准确鉴别区分,具有良好的鉴别诊断价值,还可对心脏肿瘤分布的位置进行确定。

Objective To investigate the application value of echocardiography examination in the differential diagnosis of benign and malignant cardiac tumors.Methods A total of 85 patients with cardiac tumors treated in our hospital from January 2018 to October 2020 were included in the study,and all underwent computed tomography(CT),magnetic resonance imaging(MRI) and echocardiography examination.Taking the results of surgical pathological diagnosis as reference,the differential diagnosis results and diagnostic efficacy of CT,MRI and echocardiography examination in benign and malignant cardiac tumors were compared;the consistency between CT,MRI,echocardiography examination and surgical pathological diagnosis results was analyzed;the coincidence rates of CT,MRI and echocardiography examination in the localization diagnosis of cardiac tumors were compared.Results Among the 85 patients with cardiac tumors,54 cases were diagnosed as cardiac malignant tumors(positive) and 31 cases as cardiac benign tumors(negative) by surgical and pathological diagnosis.Referring to the results of surgical pathological diagnosis,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of MRI and echocardiography examination in the differential diagnosis of benign and malignant cardiac tumors were higher than those of CT examination(P <0.05);there were no significant differences in sensitivity,specificity,accuracy,positive predictive value and negative predictive value between MRI and echocardiography examination(P >0.05).In the differential diagnosis of benign and malignant cardiac tumors,there was moderate consistency between CT examination and surgical pathological diagnosis;there were high consistency between MRI,echocardiography examination and surgical pathological diagnosis.The coincidence rate of MRI and echocardiography examination in the diagnosis of left atrial and right atrial cardiac tumors were higher than those of CT examination(P<0.05);there was no significant difference between MRI and echocardiography examination in the diagnosis coincidence rate of left atrial and right atrial cardiac tumors(P>0.05);there was no significant difference in the diagnostic coincidence rate of right ventricular cardiac tumors among CT,MRI and echocardiography examination(P >0.05).Conclusion Echocardiography examination can accurately differentiate benign and malignant cardiac tumors,which has good value in differential diagnosis,and can also determine the location of the distribution of cardiac tumors.
