摘要:
目的 探究斑块的18F-NaF摄取与斑块的纤维帽破裂(FCR)间的相关性,以及18F-NaF摄取阳性与FCR是否存在相关性。 方法 选取我院神经外科在1年内收治的确诊颈动脉分叉处粥样硬化的患者共31例,行高分辨磁共振血管壁成像检查(HR-VWI)并用MR-VPD软件对斑块FCR情况进行分析,并于检查后1周内行18F-NaF PET/CT检查。根据18F-NaF在颈动脉的摄取程度,将患者分为18F-NaF摄取阳性组和18F-NaF摄取阴性组,分析组间斑块FCR的差异。 结果 31例患者中,双侧颈动脉分叉处均有斑块的患者为23例,其余8例为单侧颈动脉斑块,共收集54枚斑块。在54条动脉粥样硬化的颈动脉中,18F-NaF显影阳性的颈动脉为33条,18F-NaF显影阴性的颈动脉为21条,颈动脉显像阳性率为61.11%,阴性率为38.89%。18F-NaF阳性组存在FCR的斑块数量占比为58%,18F-NaF阴性组存在斑块FCR占比为19%,两组间斑块FCR情况的差异有统计学意义,18F-NaF摄取阳性的斑块FCR的占比较18F-NaF摄取阴性的斑块更多(t=2.034,P=0.045)。 结论 18F-NaF摄取阳性的斑块较18F-NaF摄取阴性的斑块FCR几率更大,18F-NaF摄取在一定程度上反映了斑块FCR情况,进而评估斑块易损性。 -

Abstract:Objective To investigate the correlation between 18F-NaF uptake of plaques and fibrous cap rupture (FCR) of plaques, and the correlation between 18F-NaF uptake positivity and FCR. Methods Thirty-one patients with confirmed atherosclerosis at the carotid bifurcation who were admitted to our hospital within a year of diagnosis were selected. The patients underwent high-resolution magnetic resonance vessel wall imaging with MR-VPD software. The plaque FCR conditions was analyzed. The 18F-NaF PET / CT was performed with in 1 week after high-resolution magnetic resonance vessel wall imaging examination. Based on the extent of 18F-NaF uptake in carotid arteries, patients were divided into 18F-NaF uptake positive and 18F-NaF uptake negative groups. Differences of plaque FCR between groups were analyzed. Results There were 23 patients with both plaques in bilateral carotid bifurcations out of 31 patients and the remaining 8 patients with unilateral carotid plaques were included in this study. Fifty-four plaques were collected. Among 54 atherosclerotic carotid arteries, 33 carotid arteries were positive by 18F-NaF imaging and 21 carotid arteries were negative by 18F-NaF imaging, showing 61.11% positive and 38.89% negative carotid artery images. The proportion of plaques with FCR present was 58% in the 18F-NaF positive group and 19% in the 18F-NaF negative group. The difference in the FCR situation of plaques between the two groups was statistically significant, with a higher proportion of plaques positive for 18F-NaF uptake having FCR than plaques negative for 18F-NaF uptake.(t=2.034, P=0.045). Conclusion Plaques positive for 18F-NaF uptake has greater odds of FCR than plaques negative for 18F-NaF uptake. 18F-NaF uptake to some extent reflects plaques with FCR, which in turn assesses plaque vulnerability. -
