目的探讨磁共振在颈动脉狭窄和颈动脉斑块性质中的诊断意义。方法 42例颈动脉狭窄和颈动脉粥样硬化斑块患者,均给予磁共振检查,实施手术治疗,并取相关动脉标本进行病理组织学检查。结果 42例患者中,共存在66支颈动脉狭窄,轻度狭窄16支(24.2%)、中度狭窄26支(39.4%)、重度狭窄22支(33.3%)、闭塞2支(3.0%)。磁共振共检出斑块内纤维帽个数为24个。本组患者通过病理组织学检查观察到的硬斑块15例,软斑块10例;通过磁共振观察到的硬斑块13例,软斑块11例。经统计学检验,采用磁共振和病理组织学检查对斑块性质(软斑块和硬斑块)诊断,差异无统计学意义(P>0.05)。结论磁共振在颈动脉狭窄和颈动脉斑块性质诊断方面具有重要的临床意义,值得推广应用。
Objective To investigate the diagnostic value of magnetic resonance in carotid artery stenosis and carotid plaque. Methods 42 cases of carotid artery stenosis and carotid atherosclerosis plaque were given magnetic resonance imaging, the implementation of surgical treatment, and take relevant arteries for histopathological examination. Results There were 66 carotid stenoses, 16 mild stenoses (24.2%), 26 moderate stenoses (39.4%), 22 severe stenoses (33.3%) and 2 occlusions (3.0%) in 42 patients . The total number of fibrous caps detected by MRI was 24. This group of patients by pathological examination of the observed 15 cases of plaque, soft plaque in 10 cases; by magnetic resonance imaging observed in 13 cases of soft plaque in 11 cases. Statistically, the use of magnetic resonance and histopathological examination of plaque properties (soft plaque and hard plaque) diagnosis, the difference was not statistically significant (P> 0.05). Conclusion MRI has important clinical significance in the diagnosis of carotid artery stenosis and carotid plaque. It is worth to be popularized and applied.
