摘要/Abstract

摘要： 目的对比多层螺旋CT与高场强磁共振肝脏三维容积快速扫描(LAVA)增强诊断乙型肝炎肝硬化背景小肝癌的准确度。方法回顾性分析苏州高新区人民医院2019年7月—2021年12月收治的72例乙型肝炎肝硬化背景小肝癌患者的临床病历,以病理学检测为诊断金标准,另选100例乙型肝炎肝硬化背景肝脏良性结节患者进行对照分析。分析多层螺旋CT和MRI扫描在小肝癌病灶中的检出率。分析多层螺旋CT和MRI扫描在肝脏良性病变中的检出率。ROC分析多层螺旋CT和MRI扫描对小肝癌的诊断价值。结果在72例乙型肝炎肝硬化背景小肝癌患者中共检出80个病灶,多层螺旋CT和MRI扫描分别检出65个和74个病灶,MRI扫描病灶检出率高于CT(χ²=4.440,P=0.035)。100例肝脏良性病变患者中肝囊肿63例、肝血管瘤27例、肝脏炎性包块10例。多层螺旋CT扫描检出83例,MRI扫描检出91例,两组肝脏良性病变检出率无差异统计学意义(χ²=2.829,P=0.093)。CT增强扫描动脉期阳性检出率高于CT平扫(P<0.05)。MRI增强扫描动脉期阳性检出率高于T2WI和T1WI(均P<0.05)。MRI较CT扫描对小肝癌的诊断效能更高(P<0.05)。结论相对于多层螺旋CT扫描,LAVA序列应用在高场强MRI扫描中可更为准确地诊断小肝癌。

Abstract: Objective To compare the accuracy of multi-slice spiral CT and high field magnetic resonance imaging (MRI) liver acceleration volume acquisition (LAVA) in the diagnosis of small hepatocellular carcinoma (HCC) in the background of hepatitis B cirrhosis.Methods The clinical records of 72 patients with small HCC with hepatitis B cirrhosis background treated in our hospital from July 2019 to December 2021 were analyzed retrospectively. The diagnosis was confirmed by pathological test as the gold standard, and 100 patients with benign liver nodules with hepatitis B cirrhosis background were selected as control. The detection rates of multi-slice spiral CT and MRI in small HCC lesions and benign liver lesions were compared. ROC analysis was used to evaluate the diagnostic value of multi-slice spiral CT and MRI in small HCC.Results A total of 80 lesions were detected in 72 patients with small HCC in the background of hepatitis B cirrhosis. 65 and 74 lesions were detected by multi-slice spiral CT and MRI respectively. The detection rate of lesions by MRI was higher than that by multi-slice spiral CT (χ²=4.440, P=0.035). Among the 100 patients with benign liver lesions, there were 63 cases of hepatic cyst, 27 cases of hepatic hemangioma and 10 cases of hepatic inflammatory mass. 83 cases were detected by multi-slice spiral CT and 91 cases by MRI. There was no significant difference in the detection rate of benign liver lesions between the two groups (χ²=2.829, P=0.093). The positive rate of arterial phase in CT scan was higher than that in plain scan (P<0.05). The positive detection rate of arterial phase in MRI was higher than that in T2WI and T1WI (both P<0.05). MRI was more effective than CT in the diagnosis of small HCC (P<0.05).Conclusion Compared with multi-slice spiral CT scanning, the application of LAVA sequence in high field MRI scanning can more accurately diagnose small HCC.
