The aim of this study was to assess quantitatively the Kupffer-phase enhancement patterns of hepatic hemangiomas in contrast-enhanced ultrasound (CEUS) with Sonazoid. A total of 46 patients with 46 hepatic hemangiomas (17.1 ± 6.2 mm in diameter, 34 typical type and 12 high-flow type) underwent CEUS in the Kupffer phase. The lesion-to-liver contrast ratio in the Kupffer phase was quantitatively assessed for both types of hemangioma. Most of the hepatic hemangiomas, whether or not they were the high-flow type, were iso- to hypo-echoic relative to the surrounding liver parenchyma. The contrast ratio was -5.33 ± 6.70 dB for the high-flow hemangiomas and -4.54 ± 6.28 dB for the typical hemangiomas. There was no significant difference in contrast ratio between the two types of lesions (p = 0.73). All of the hemangiomas, whether of typical or high-flow type, are iso- to hypo-echoic relative to the surrounding liver parenchyma on Kupffer-phase imaging.
本研究旨在利用声诺维通过超声造影(CEUS)对肝血管瘤的库普弗期增强模式进行定量评估。共有46例患者的46个肝血管瘤(直径17.1±6.2毫米,34个典型型和12个高流量型)接受了库普弗期CEUS检查。对两种类型的血管瘤均定量评估了库普弗期的病灶-肝脏对比率。大多数肝血管瘤,无论是否为高流量型,相对于周围肝实质均呈等回声至低回声。高流量血管瘤的对比率为-5.33±6.70dB,典型血管瘤的对比率为-4.54±6.28dB。两种类型病灶的对比率无显著差异(p = 0.73)。在库普弗期成像中,所有血管瘤,无论是典型型还是高流量型,相对于周围肝实质均呈等回声至低回声。
