目的 对比径向采集逐点编码缩短时间MR血管成像(PETRA-MRA)、时间飞跃法MRA (TOF-MRA)及CT血管成像(CTA)评估颅脑前循环动脉狭窄程度及长度的效能。方法 回顾性分析56例经颅脑数字减影血管造影(DSA)确诊颅脑前循环动脉狭窄患者的颅脑PETRA-MRA、TOF-MRA和CTA资料,采用组内相关系数(ICC)及Bland-Altman法观察PETRA-MRA与TOF-MRA、CTA评估颅脑前循环动脉狭窄程度及长度与DSA结果的一致性,以及分析上述评估结果与DSA的相关性。结果 Bland-Altman分析显示,以DSA为标准,PETRA-MRA评估颅脑前循环动脉狭窄程度的变异系数、偏差及一致性限度范围分别为13.30%、1.04及(-13.37,15.46),TOF-MRA分别为15.89%、2.81及(-14.68,20.29),CTA分别为20.17%、11.19及(-12.66,35.04)。PETRA-MRA、TOF-MRA及CTA评估颅脑前循环动脉狭窄程度(ICC=0.92、0.89、0.80),以及PETRA-MRA、TOF-MRA评估颅脑前循环动脉狭窄长度与DSA结果的一致性均好(ICC=0.99、0.97),而CTA评估颅脑前循环动脉狭窄长度与DSA结果的一致性差(ICC=0.30)。PETRA-MRA、TOF-MRA及CTA评估颅脑前循环动脉狭窄程度(rs=0.94、0.86、0.80)及其长度(rs=0.98、0.97、0.70)均与DSA结果呈正相关(P均<0.01)。结论 PETRA-MRA评估颅脑前循环动脉狭窄的效能优于TOF-MRA及CTA。 |

Objective To compare the efficacies of pointwise encoding time reduction with radial acquisition MR angiography (PETRA-MRA), time of flight MRA (TOF-MRA) and CT angiography (CTA) for assessing the degree and length of stenosis of intracranial anterior circulation arteries. Methods Data of cranial PETRA-MRA, TOF-MRA and CTA of 56 patients with stenosis of intracranial anterior circulation arteries confirmed by digital subtraction angiography (DSA) were retrospectively analyzed. Intra-class correlation coefficient (ICC) and Bland-Altman plots were used to explore the consistencies of PETRA-MRA, TOF-MRA and CTA with DSA for assessing the degree and length of stenosis of intracranial anterior circulation artery, and the correlations with DSA results were analyzed. Results Bland-Altman plots showed that taken DSA results as the gold standard, the coefficient of variation, Bias and limits of agreement of PETRA-MRA for evaluation on the degree of anterior cerebral circulation artery stenosis was 13.30%, 1.04 and (-13.37, 15.46), respectively, of TOF-MRA was 15.89%, 2.81 and (-14.68, 20.29), while of CTA was 20.17%, 11.19 and (-12.66, 35.04), respectively. The degree of stenosis of anterior cerebral circulation artery assessed with PETRA-MRA, TOF-MRA and CTA were in good agreement (ICC=0.92, 0.89, 0.80) with DSA results, so were the length of stenosis assessed with PETRA-MRA, TOF-MRA (ICC=0.99, 0.97), but the length of stenosis assessed with CTA was in bad agreement (ICC=0.30) with DSA results. The degree (rs=0.94, 0.86, 0.80) and length (rs=0.98, 0.97, 0.70) of stenosis of anterior cerebral circulation artery assessed with PETRA-MRA, TOF-MRA and CTA were all positively correlated with DSA results (all P<0.01). Conclusion The efficacy of PETRA-MRA was higher than that of TOF-MRA and CTA for assessing stenosis of intracranial anterior circulation artery. |
