- Abstract:
- Objective To analyze and observe the application value of three-dimensional T1 weighted sampling perfection with
application-optimized contrast using different flip angle evolutions (3D T1-SPACE) high-resolution magnetic resonance vessel
wall imaging in the diagnosis of cerebrovascular diseases. Methods Atotal of 100 patients with ischemic cerebrovascular diseases
who received 3D T1-SPACE high-resolution magnetic resonance vessel wall imaging were enrolled and then divided into
symptomatic group (n=61) and asymptomatic group (n=39) according to whether they were symptomatic or not. The quantitative
indicators of blood vessels and plaques were compared between two groups of patients, and the indicators included vessel area
at lesion level (VAMLN), lumen area at lesion level (LAMLN), vessel area at reference level (VARL), lumen area at reference level (LARL),
stenosis rate, plaque load, remodeling index (RI), eccentricity index (EI) and the proportions of positive remodeling, eccentric
plaque, irregular plaque surface and plaque at the anterior wall. Logistic regression model was used to analyze the independent
risk factors affecting middle cerebral artery stenosis of symptomatic atherosclerosis. Results No statistical difference was found
between two groups in VAMLN, LAMLN, VARL, LARL, stenosis rate and plaque load (P>0.05). The RI and EI of symptomatic group
were significantly higher than those of asymptomatic group (P<0.05), and the proportions of positive remodeling, eccentric plaque,
irregular plaque surface and plaque at the anterior wall were also significantly higher than those of asymptomatic group (P<0.05).
Logistic regression analysis results revealed that lumen positive remodeling, irregular plaque surface and plaque at the anterior
wall were the independent risk factors affecting middle cerebral artery stenosis of symptomatic atherosclerosis. Conclusion 3D
T1-SPACE high-resolution magnetic resonance vessel wall imaging can be used to effectively assess the characteristics of arterial plaques in patients with cerebrovascular diseases. The middle cerebral artery stenosis of symptomatic atherosclerosis is usually
accompanied by lumen positive remodeling, irregular plaque surface and plaque at the anterior wall, having a guiding significance
for predicting the risk and classification of cerebrovascular accidents in patients.
