The most typical findings helpful in diagnosing HEHE are: Presence of multiple, confluent nodules located at the liver periphery (in young to middle-aged woman), retraction of the liver capsule, marked hyperintensity on T2-weighted images, \"target-sign\" appearance, progressive centripetal contrast enhancement, and relatively high Apparent Diffusion Coefficient (ADC) values. More than ≥50% of nodules are hyper- or isointense on Hepatobiliary Phase (HBP) images.
The imaging features suggestive of PHA are: Occurrence of metastases (lungs, spleen) at the time of diagnosis, presence of a large dominant mass with smaller satellites, heterogeneity and areas of haemorrhage in a dominant mass, progressive contrast enhancement, slightly elevated ADC values as compared to other malignant liver tumours.
有助于诊断HEHE的最典型发现是:存在多个,位于肝脏外围的融合结节(年轻至中年女性),肝包膜的收缩,T2加权图像上明显的高强度,“目标标志”外观,渐进式向心对比度增强,和相对较高的表观扩散系数(ADC)值。在肝胆相(HBP)图像上,超过50%的结节是高信号或等信号。
提示PHA的影像学特征是:转移的发生(肺,脾脏)在诊断时,存在一个大的主导质量和较小的卫星,主要肿块的异质性和出血面积,渐进式对比度增强,与其他恶性肝肿瘤相比,ADC值略有升高。
