We examined the capability of a gray-scale arterial spin labeling blood flow pattern variation (BFPV) map with two different post labeling delay (PLD) times to discriminate pannus in patients with rheumatoid arthritis (RA) at 3T. There was a statistically significant difference in the BFPV values between artery, pannus, and surrounding tissue. Furthermore, the color-coded BFPV map was able to accurately distinguish pannus from other tissues. These results suggest this approach may be capable of identifying pannus noninvasively.
我们研究了具有两种不同标记后延迟(PLD)时间的灰度动脉自旋标记血流模式变化(BFPV)图在3T场强下鉴别类风湿性关节炎(RA)患者血管翳的能力。动脉、血管翳及周围组织的BFPV值存在统计学显著差异。此外,彩色编码的BFPV图能够准确地将血管翳与其他组织区分开来。这些结果表明,这种方法可能能够无创地识别血管翳。
