多排螺旋CT增强扫描诊断肝占位准确率的临床效果研究

Clinical Effect Study on Accuracy of Spiral CT Enhanced Scanning in Diagnosing Liver Masses

目的分析肝占位诊断中应用多排螺旋CT增强扫描的效果与价值。方法选取2018年1月—2022年12月江阴市第三人民医院放射科收治的56例疑似肝占位患者作为研究对象,所有研究对象均接受CT平扫、多排螺旋CT增强扫描和手术病理检查,并以手术病理检查结果作为金标准,分析比较CT平扫、多排螺旋CT增强扫描在肝占位诊断中的结果差异。结果①经手术病理检查方式,全部56例疑似肝占位患者中共确诊45例,其中存在7例肝脓肿患者、5例肝转移瘤患者、6例原发性肝细胞癌患者、16例肝囊肿患者、2例肝脏局灶性增生和9例肝血管瘤患者,剩余11例非肝占位患者经病理诊断确诊为脂肪肝;②经多排螺旋CT增强扫描发现,全部56例疑似肝占位患者中共确诊43例,其中存在6例肝脓肿患者、5例肝转移瘤患者、6例原发性肝细胞癌患者、15例肝囊肿患者、2例肝脏局灶性增生和9例肝血管瘤患者;③经CT平扫发现,全部56例疑似肝占位患者中共确诊37例,其中存在5例肝脓肿患者、4例肝转移瘤患者、5例原发性肝细胞癌患者、13例肝囊肿患者和10例肝血管瘤患者;④通过比较不同检查方式在肝占位诊断中的结果发现,多排螺旋CT增强扫描的诊断灵敏度、特异度和准确度均高于CT平扫,差异有统计学意义(P<0.05);⑤通过比较不同检查方式的图像质量发现,多排螺旋CT增强扫描图像的优良率要高于CT平扫,差异有统计学意义(P<0.05)。结论在肝占位诊断中,多排螺旋CT增强扫描具有灵敏度、特异度和准确度高的优点,且该检查方式的图像质量也较高,有助于医生更好地明确受检者是否患有肝占位,应用价值较高。

Objective To analyze effect and value of multi row spiral CT enhanced scanning in diagnosis of liver masses.Methods The paper chose 56 suspected liver mass patients in Radiology Department of Jiangyin City the Third People's Hospital from January 2018 to December 2022 as study subjects,treated with CT plain scan,multi row spiral CT enhanced scan,and surgical pathological examination,analyzed and compared difference in diagnosis of liver mass between CT plain scan and multi row spiral CT enhanced scan with gold standard of results of surgical pathological examination.Results①Through surgical and pathological examination,45 cases suspected liver masses were diagnosed among 56 cases,including 7 cases of liver abscess,5 cases of liver metastasis,6 cases of primary hepatocellular carcinoma,16 cases of liver cyst,2 cases of focal liver hyperplasia,and 9 cases of liver hemangioma.The remaining 11 cases with no liver masses were diagnosed with fatty liver through pathological diagnosis.②Through multi row spiral CT enhanced scanning,43 cases suspected liver masses were diagnosed among 56 cases,including 6 cases of liver abscess,5 cases of liver metastasis,6 cases of primary hepatocellular carcinoma,15 cases of liver cyst,2 cases of focal liver hyperplasia,and 9 cases of liver hemangioma through CT plain scan.③Based on CT plain scan,37 cases out of 56 suspected liver mass patients were diagnosed,including 5 cases of liver abscess,4 cases of liver metastasis,5 cases of primary hepatocellular carcinoma,13 cases of liver cyst,and 10 cases of liver hemangioma.④By comparing results of different examination methods in diagnosis of liver masses,it was found that diagnostic sensitivity,specificity,and accuracy of multi row spiral CT enhanced scan was higher than CT plain scan(P<0.05).⑤By comparing image quality of different examination methods,it was found excellent rate of multi row spiral CT enhanced scan images was higher than CT plain scan,with(P<0.05).Conclusion Multi row spiral CT enhanced scanning has advantages of high sensitivity,specificity,and accuracy in diagnosis of liver masses,and image quality of the examination method is higher,doctors can determine liver masses of patients better,which has higher application value.
