背景:β-连环蛋白突变的肝细胞腺瘤(β-HCA)在磁共振成像(MRI)的肝胆阶段(HBP)可以出现等强度到高。鉴于β-HCA的患病率相对较低,先前的研究显示不同亚型之间HBP信号强度的统计学显著差异的能力有限.
目的:评估HBPMRI鉴别β-HCA与其他亚型的诊断效能。
方法:系统综述和荟萃分析。
方法:纳入了10项原始研究,产生266例397例HCA患者(9%,36/397β-HCA和91%,361/397非β-HCA)。
■1.5T和3.0T,HBP。
结果:PubMed,WebofScience,我们在2000年1月1日至2023年8月31日的Embase数据库中搜索了所有报道组织病理学证实的HCA亚型患者HBP信号强度的文章.QUADAS-2用于评估偏倚风险和对适用性的担忧。
方法:使用单变量随机效应模型计算合并估计值。异质性估计用I2异质性指数进行评估。使用Meta回归(混合效应模型)来检验HCA组之间HBP信号患病率的差异。统计学意义的阈值设定为P<0.05。
结果:高强度HBP与β-HCAs相关(β-HCAs合并患病率为72.3%,非β-HCAs为6.3%)。合并的敏感性和特异性分别为72.3%(95%置信区间54.1-85.3)和93.7%(93.8-97.7),分别。由于一项研究,特异性具有相当大的异质性,I2为83%,但不是灵敏度(I2=0)。排除这项研究后,合并的敏感性和特异性分别为77.4%(59.6-88.8)和94.1%(88.9-96.9),没有实质性的异质性。一项研究对患者选择有很高的偏倚风险,两项研究在两个领域被评为不清楚。
结论:HBPMRI的等高强度可能有助于将β-HCA亚型与其他HCA区分开,具有较高的特异性。然而,汇总估计值存在异质性.

BACKGROUND: Beta-catenin-mutated hepatocellular adenomas (β-HCAs) can appear iso- to hyperintense at the hepatobiliary phase (HBP) at magnetic resonance imaging (MRI). Given the relatively lower prevalence of β-HCAs, prior studies had limited power to show statistically significant differences in the HBP signal intensity between different subtypes.
OBJECTIVE: To assess the diagnostic performance of HBP MRI to discriminate β-HCA from other subtypes.
METHODS: Systemic review and meta-analysis.
METHODS: Ten original studies were included, yielding 266 patients with 397 HCAs (9%, 36/397 β-HCAs and 91%, 361/397 non-β-HCAs).
UNASSIGNED: 1.5 T and 3.0 T, HBP.
RESULTS: PubMed, Web of Science, and Embase databases were searched from January 1, 2000, to August 31, 2023, for all articles reporting HBP signal intensity in patients with histopathologically proven HCA subtypes. QUADAS-2 was used to assess risk of bias and concerns regarding applicability.
METHODS: Univariate random-effects model was used to calculate pooled estimates. Heterogeneity estimates were assessed with I2 heterogeneity index. Meta-regression (mixed-effect model) was used to test for differences in the prevalence of HBP signal between HCA groups. The threshold for statistical significance was set at P < 0.05.
RESULTS: HBP iso- to hyperintensity was associated with β-HCAs (pooled prevalence was 72.3% in β-HCAs and 6.3% in non-β-HCAs). Pooled sensitivity and specificity were 72.3% (95% confidence interval 54.1-85.3) and 93.7% (93.8-97.7), respectively. Specificity had substantial heterogeneity with I2 of 83% due to one study, but not for sensitivity (I2 = 0). After excluding this study, pooled sensitivity and specificity were 77.4% (59.6-88.8) and 94.1% (88.9-96.9), with no substantial heterogeneity. One study had high risk of bias for patient selection and two studies were rated unclear for two domains.
CONCLUSIONS: Iso- to hyperintensity at HBP MRI may help to distinguish β-HCA subtype from other HCAs with high specificity. However, there was heterogeneity in the pooled estimates.
