早期肝癌患者在临床诊断期间使用肝脏超声造影诊断其病灶位置和转移中的应用效果

目的分析肝癌患者在临床诊断期间使用肝脏超声造影诊断病灶位置以及转移中的应用效果。方法随机选取我院有既往肝癌手术史的156例术后门诊检查患者为研究对象,对其实施肝脏超声造影诊断(CEUS)检查和CT检查,分析患者的病灶位置、病灶特征、转移情况以及检查准确度、灵敏度、特异度。结果经过对156例患者实施病理活检和甲胎蛋白检测以患者既往病灶位置为参考后,发现复发或转移病灶共236个,其中肝左叶共123个,肝右叶共113个,有165个病灶为恶性肿瘤病灶,71个病灶为良性病灶,其中22例为肝血管瘤,36例为肝局灶性结节性增生,13例为肝脏腺瘤;直径<1 cm病灶共157个,直径≥1 cm病灶共79个。检查后发现超声造影检查准确度、灵敏度、特异度、病灶位置检出度、对于直径<1 cm的检出率明显较CT检查更高,(P<0.05),对于直径≥1 cm的病灶,两种检查方法检出率相差无几,(P>0.05)。结论早期肝癌患者实施肝脏超声造影诊断,可有效提升对患者的疾病准确度、灵敏度与特异度,同时,有效确诊患者病灶位置,对于直径<1 cm的病灶检出率较高,可对病情早期确诊,是一种具有...

Application of Contrast-enhanced Ultrasonography in the Diagnosis of the Location and Metastasis of Early Liver Cancer

Objective To analyze the application effect of contrast-enhanced ultrasound(CEUS)in the clinical diagnosis of liver cancer.Methods 156 outpatients with a history of liver cancer surgery in our hospital from were randomly selected as the study objects.CEUS and CT were performed to analyze the location,characteristics,metastasis,accuracy,sensitivity and specificity of the patients.Results A total of 236 recurrent or metastatic lesions were found in 156 patients after pathological biopsy and alpha fetoprotein detection,including 123 in the left lobe,113 in the right lobe,165 in malignant lesions,71 in benign lesions,22 in hemangioma,36 in nodular hyperplasia and 13 in liver There were 157 lesions with a diameter of less than 1 cm and 79 lesions with a diameter of more than 1 cm.After the examination,it was found that the accuracy,sensitivity,specificity,detection degree of focus location and detection rate for lesions with diameter less than 1 cm were significantly higher than those of CT(P<0.05).For lesions with diameter more than 1 cm,the detection rates of the two methods were almost the same(P>0.05).Conclusions Contrast-enhanced ultrasound can effectively improve the accuracy,sensitivity and specificity of the disease in patients with early liver cancer.At the same time,it can effectively diagnose the location of the lesions.The detection rate of the lesions with diameter less than 1 cm is high,and it can be diagnosed in the early stage of the disease.It is a diagnostic method with high practical value.
