摘要
目的探讨多层螺旋CT(MSCT)增强扫描用于肝癌诊断的价值及符合率。方法选取2019年1月—2022年1月盐城市第一人民医院收治的原发性肝癌患者66例(均经过手术病理检查确诊),给予MSCT平扫、增强扫描,分析不同扫描方法的应用价值。结果CT增强扫描与平扫的诊断符合率分别为96.97%与65.15%,CT增强扫描符合率明显高于CT平扫(P<0.05)。手术病理得知病灶数共计84个;CT增强扫描动脉期检出病灶81个,占比96.43%,静脉期检出病灶78个,占比92.86%,平衡期检出病灶79个,占比94.05%,CT增强扫描相比CT平扫的检出病灶数占比均明显更高(P<0.05)。CT增强扫描对弥漫型、结节型、巨块型患者的诊断符合率分别为95.24%、96.55%、100.00%,CT平扫的符合率分别为52.38%、55.17%、100.00%,CT增强扫描对于弥漫型、结节型患者的检出率均明显高于CT平扫(P<0.05)。CT平扫主要表现为低密度;CT增强扫描动脉期多数为不均匀明显强化,静脉期病灶强化减退,主要为低密度,少数为等密度,平衡期继续减退强化程度,主要为低密度,少数等密度或者稍高密度。结论对肝癌患者而言,加强多层螺旋CT增强扫描具有较高的诊断符合率,便于明确具体病变分型,为疾病的诊疗提供科学的影像学依据,值得采纳并推广。
Objective To explore value and coincidence rate of multi-slice spiral CT enhanced scanning in diagnosis of liver cancer.Methods The paper chose 66 patients with primary liver cancer admitted to Yangcheng City the First People's Hospital from January 2019 to January 2022,confirmed with surgical and pathological examinations,and analyze application value of different scanning methods with multi slice spiral CT plain and enhanced scanning.Results Diagnostic accuracy of contrast-enhanced CT scan and plain CT scan was 96.97%and 65.15%respectively.Accuracy of contrast-enhanced CT scan was significantly higher than plain CT scan(P<0.05).Surgical pathology revealed 84 lesions.CT enhanced scanning detected 81 lesions in arterial phase,accounting for 96.43%,78 lesions were detected in the venous phase,accounting for 92.86%,and 79 lesions were detected in balance phase,accounting for 94.05%.CT enhanced scanning showed significantly higher proportion of detected lesions than CT plain scanning(P<0.05).Diagnostic accuracy of CT enhanced scan for diffuse,nodular,and massive patients was 95.24%,96.55%,and 100.00% respectively.Accuracy of CT plain scan was 52.38%,55.17%,and 100.00%respectively.Detection rate of CT enhanced scan for diffuse and nodular patients was significantly higher than CT plain scan(P<0.05).Main manifestation of MSCT plain scan was low density,while MSCT enhanced scan showed,most of the arterial phase had uneven and obvious enhancement,at venous phase,enhancement of lesion decreased with low density mainly,a few showed equal density.During equilibrium period,degree of enhancement decreased,with low density mainly,a few showed equal density or slightly high density.Conclusion Enhanced multi-slice spiral CT enhanced scanning can achieve high diagnostic accuracy,facilitate identification of specific lesion types,and provide scientific imaging basis for disease diagnosis and treatment of liver cancer patients,which is worthy of application and promotion.
