OBJECTIVE To investigate the correlation between carotid artery stenosis (CAS) measured by magnetic resonance imaging (MRI) and the coronary stenosis (CS) determined by computed tomography angiography (CTA). METHODS In this prospective study, 42 subjects diagnosed with coronary artery disease (CAD) underwent MRI and CTA examinations. The severity degree and number of CAS, the score, detection rate and type of carotid plaque, and also the severity degree and number of CS were assessed. Spearman's rank correlation test was used to evaluate the correlation between CAS and CS. RESULTS CS was detected in 42 (100%) subjects, while CAS was detected in 36 (85.7%) subjects. Distribution of CAS severity grades in multiple-vessel group was significantly different from other groups, which with more moderate and severe stenosis (p < 0.05). A positive and significant correlation between the CAS severity and CS severity (r = 0.612, p < 0.05), and the number of involved coronary vessels (r = 0.572, p < 0.05) were observed, respectively. Both detection rate (r = 0.587, p < 0.05) and score (r = 0.735, p < 0.05) of carotid plaque showed a good correlation with the number of involved coronary vessels. After carotid MRI, 71 carotid plaques were detected in 42 subjects, with an incidence rate of 9.9% in subjects with mild CS, 18.3% in moderate CS and 71.8% in severe CS. CONCLUSION Correlation between CAS measured by MRI and CS determined by CTA was identified in present study. These results indicated that the non-invasive CAS evaluation employing the MRI may be clinically useful for the assessment of CS.

通过计算机断层扫描血管造影术检测到的颈动脉磁共振成像与冠状动脉狭窄之间的关联。

目的探讨磁共振成像(MRI)测量的颈动脉狭窄(CAS)与计算机断层血管造影(CTA)测定的冠状动脉狭窄(CS)之间的相关性。方法在这项前瞻性研究中,对42位诊断出患有冠状动脉疾病(CAD)的受试者进行了MRI和CTA检查。评估CAS的严重程度和数量,颈动脉斑块的评分,检出率和类型,以及CS的严重程度和数量。用Spearman秩相关检验评估CAS和CS之间的相关性。结果在42位(100%)受试者中检测到CS,而在36位(85.7%)受试者中检测到CAS。多支血管组的CAS严重度等级分布与其他组明显不同,后者的中度和重度狭窄程度更高(p <0.05)。分别观察到CAS严重度和CS严重度之间的正相关和显着正相关(r = 0.612,p <0.05)和冠状动脉受累血管数量(r = 0.572,p <0.05)。颈动脉斑块的检出率(r = 0.587,p <0.05)和得分(r = 0.735,p <0.05)均与冠状动脉受累血管数目相关。颈动脉MRI后,在42位受试者中检测到71个颈动脉斑块,轻度CS患者的发生率为9.9%,中度CS患者的发生率为18.3%,重度CS患者的发生率为71.8%。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。分别观察到612例(p <0.05)和冠状动脉受累血管数(r = 0.572,p <0.05)。颈动脉斑块的检出率(r = 0.587,p <0.05)和得分(r = 0.735,p <0.05)均与冠状动脉受累血管数目相关。颈动脉MRI后,在42位受试者中检测到71个颈动脉斑块,轻度CS患者的发生率为9.9%,中度CS患者的发生率为18.3%,重度CS患者的发生率为71.8%。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。分别观察到612例(p <0.05)和冠状动脉受累血管数(r = 0.572,p <0.05)。颈动脉斑块的检出率(r = 0.587,p <0.05)和得分(r = 0.735,p <0.05)均与冠状动脉受累血管数目相关。颈动脉MRI后,在42位受试者中检测到71个颈动脉斑块,轻度CS患者的发生率为9.9%,中度CS患者的发生率为18.3%,重度CS患者的发生率为71.8%。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。05)和颈动脉斑块评分(r = 0.735,p <0.05)显示与受累冠状动脉数量有很好的相关性。颈动脉MRI后,在42位受试者中检测到71个颈动脉斑块,轻度CS患者的发生率为9.9%,中度CS患者的发生率为18.3%,重度CS患者的发生率为71.8%。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。05)和颈动脉斑块评分(r = 0.735,p <0.05)显示与受累冠状动脉数量有很好的相关性。颈动脉MRI后,在42位受试者中检测到71个斑块,轻度CS患者的发生率为9.9%,中度CS患者的发生率为18.3%,重度CS患者的发生率为71.8%。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。结论本研究确定了MRI测定的CAS与CTA测定的CS之间的相关性。这些结果表明采用MRI的无创CAS评估在临床上可能对CS评估有用。
