摘　　要：目的:探究3.0T磁共振增强检查技术对于脑血管斑块诊断分级的研究价值。方法:选取我院2019年2月1日至2022年12月31日符合条件的70例存在脑血管斑患者,根据脑血管斑块诊断分级分为Ⅰ级组(n=23)、Ⅱ级组(n=25)、Ⅲ级组(n=22),所有患者均进行3.0T磁共振增强检查,以数字减影血管造影(DSA)检查结果为金标准。评估斑块检出情况、诊断效能。结果:Ⅰ级组23例患者检出42处斑块,其中环形斑块最多,检出10例,占比23.81%;其次是前下壁斑块,检出6例,占比14.29%。Ⅱ级组25例患者检出62处斑块,其中环形斑块最多,检出15例,占比24.19%;其次是前下壁斑块检出10例,占比16.13%。Ⅲ级组22例患者检出80处斑块,其中环形斑块最多,检出28例,占比35.00%;其次是前下壁斑块检出20例,占比25.00%。由此可知,脑血管斑块诊断分级越高,检测出的斑块越多,病情越严重。ROC曲线结果表明,子宫体积、卵巢体积、卵泡直径及卵泡个数诊断的曲线下面积分别为0.905、0.924、0.982,其中Ⅲ级准确度(94.47%)和灵敏度(100.00%)高于Ⅰ级准确度(86.31%)和灵敏度(92.45%)与Ⅱ级准确度(90.88%)和灵敏度(95.32%)。结论:3.0T磁共振增强检查技术对于脑血管斑块诊断分级具有较高的诊断价值,可为临床医生下诊断和制定治疗方案带来有利的证据。Objective:To explore the value of 3.0T enhanced magnetic resonance examination in the diagnosis and classification of cerebrovascular plaque.Methods:70 eligible patients with cerebrovascular plaques in our hospital from February 1,2020 to December 31,2022 were selected and divided into gradeⅠgroup(n=23),gradeⅡgroup(n=25)and gradeⅢgroup(n=22)according to the diagnosis grade of cerebrovascular plaques.All patients underwent 3.0T MRI enhancement examination.The result of digi⁃tal subtraction angiography(DSA)is the gold standard.Evaluate the plaque detection and diagnostic effi⁃cacy.Results:42 plaques were detected in 23 patients in gradeⅠgroup,of which annular plaques were the most,with 10 cases,accounting for 23.81%;followed by anterior inferior wall plaque,6 cases were de⁃tected,accounting for 14.29%.In the gradeⅡgroup,62 plaques were detected in 25 patients,of which annular plaques were the most,with 15 cases,accounting for 24.19%.The anterior inferior wall plaque was detected in 10 cases,accounting for 16.13%.In the gradeⅢgroup,80 plaques were detected in 22 patients,of which annular plaques were detected in 28 patients,accounting for 35.00%;20 cases(25.00%)were detected in anterior inferior wall plaque.In conclusion,the higher the cerebrovascular plaque diagnostic grade,the more plaques detected and the more serious the disease.ROC results showed that the areas under the curve of uterine volume,ovarian volume,follicle diameter and number of follicles were 0.905,0.924 and 0.982,respectively.The accuracy(94.47%)and sensitivity(100.00%)of gradeⅢwere higher than those of gradeⅠaccuracy(86.31%)and sensitivity(92.45%)and gradeⅡaccuracy(90.88%)and sensitivity(95.32%).Conclusion:The 3.0T MRI enhancement technique has high diagnos⁃tic value for the diagnosis and classification of cerebrovascular plaque,which can bring favorable evi⁃dence for clinicians to make diagnosis and treatment plan.
