Eur Radiol:颈动脉出血性斑块那可是易损斑块,得好好检查检查!

本研究旨在探究即时非强化血管造影和斑块内出血(SNAP)成像在显示斑块内出血(IPH)的特点,并将其与磁化率准备快速采集梯度回波(MP-RAGE)序列进行比较,研究人员将研究结果发表在Eur Radiol上。

本研究旨在探究即时非强化血管造影和斑块内出血(SNAP)成像在显示斑块内出血(IPH)的特点,并将其与磁化率准备快速采集梯度回波(MP-RAGE)序列进行比较,研究人员将研究结果发表在Eur Radiol上。

本研究共纳入了54例有症状的颈动脉粥样硬化的患者(平均年龄:63.1 ± 5.7,男性38例),并行颈动脉MR成像。测量SNAP和MP-RAGE图像上IPH的有无及相应面积。分析SNAP和MP-RAGE间检出IPH的一致性及其面积。

本研究共纳入了54例患者的1368层质量良好的图像资料,分别在MP-RAGE和SNAP图像中共检出IPH分别为13%、22.6%。MP-RAGE和SNAP序列鉴别IPH具有较好的一致性(κ = 0.511, p = 0.029)。在SNAP序列中IPH的面积要明显大于MP-RAGE图像(17.9 ± 18.2 mm 2 vs. 9.2 ± 10.5 mm 2, p < 0.001)。对于SNAP检出的IPHs,MP-RAGE序列检出的IPH的面积要明显大于MP-RAGE未检出的IPH (17.9 ± 19.2 mm 2 vs. 6.4 ± 6.2 mm 2, p < 0.001)。

本研究表明,与MP-RAGE序列相比,SNAP成像能够检出更多的IPH,尤其是小IPH,这表明SNAP可能作为检出颈动脉出血性斑块更为敏感的序列。
