This study was undertaken to compare the performance of colour Doppler (CDS), power Doppler (PDS) and 3-D power Doppler sonography (3-D PDS) in the assessment of vascular pattern and vessel displacement of cervical lymph nodes. Colour Doppler (2-D CDS), power Doppler (2-D PDS) and 3-D power Doppler sonograms (3D PDS) of 145 cervical nodes were reviewed (metastases n=60, lymphoma n=30, tuberculosis n=23, reactive n=25, Kimura disease n=7). Sonograms of the three imaging modes were reviewed separately with an interval of 2 weeks. Lymph nodes were assessed for the vascular pattern (hilar, peripheral or mixed) and the presence or absence of displacement of hilar vascularity. For the assessment of displacement of hilar vascularity, only lymph nodes that showed hilar or mixed vascularity in the three imaging modes were included in the analysis. Results showed that there was a high level of agreement between CDS and PDS in assessment of vascular patterns (kappa=0.914), whereas the level of agreement between CDS and 3-D PDS (kappa=0.484) and between PDS and 3-D PDS (kappa=0.452) was low. There was a high level of agreement in the assessment of displacement of hilar vascularity among the three imaging modes (CDS and PDS, kappa=0.942; CDS and 3-D PDS, kappa=0.808; PDS and 3-D PDS, kappa=0.865). In the assessment of vascular patterns of cervical lymphadenopathy, CDS and PDS have a similar performance. However, accurate assessment of the vascular pattern of cervical nodes may be difficult using 3-D PDS. In the assessment of displacement of hilar vascularity, the performances of CDS, PDS and 3-D PDS are similar.
本研究旨在比较彩色多普勒超声(CDS)、能量多普勒超声(PDS)和三维能量多普勒超声(3-D PDS)在评估颈部淋巴结血管形态及血管移位方面的性能。回顾了145个颈部淋巴结的彩色多普勒超声(二维CDS)、能量多普勒超声(二维PDS)和三维能量多普勒超声图像(3D PDS)(转移瘤60例、淋巴瘤30例、结核23例、反应性增生25例、木村病7例)。三种成像模式的超声图像分别进行回顾,间隔2周。评估淋巴结的血管形态(门型、周边型或混合型)以及门部血管是否存在移位。对于门部血管移位的评估,仅纳入在三种成像模式中显示门型或混合型血管的淋巴结进行分析。结果显示,在评估血管形态方面,CDS和PDS之间的一致性较高(kappa=0.914),而CDS与3-D PDS之间(kappa=0.484)以及PDS与3-D PDS之间(kappa=0.452)的一致性较低。在三种成像模式中,对门部血管移位的评估一致性较高(CDS和PDS,kappa=0.942;CDS和3-D PDS,kappa=0.808;PDS和3-D PDS,kappa=0.865)。在评估颈部淋巴结病变的血管形态时,CDS和PDS具有相似的性能。然而,使用3-D PDS准确评估颈部淋巴结的血管形态可能较为困难。在评估门部血管移位方面,CDS、PDS和3-D PDS的性能相似。
