摘要
目的探讨增强MRI与超声造影用于评估高强度聚焦超声(HIFU)治疗子宫肌瘤的消融情况。方法回顾性分析我院60例HIFU治疗子宫肌瘤患者(肌瘤60个)的临床病历资料,并于治疗前及治疗后1 d分别采用MRI、超声造影检查。统计两组图像质量评分、治疗前后肌瘤体积等。结果增强MRI图像质量评分、术后无灌注区体积及平均消融率分别为(3.9±0.3)分、(81.9±82.7)cm3、(80.7±18.4)%与超声造影(2.0±0.7)分、(65.7±66.1)cm3、(71.5±19.4)%比较,差异具有统计学意义,P<0.05;增强MRI肌瘤图像显示总分为114分明显高于超声造影62分,差异具有统计学意义,P<0.05。应用增强MRI扫描检查可清晰显示肌瘤边界、大小及其与周围组织的关系;然超声造影显示边界较模糊,10例患者无法确定肌瘤边界。结论应用增强MRI可较好地评估HIFU治疗子宫肌瘤的消融程度,从而为临床治疗方案的选择及预后判断提供有力依据。
Objective To investigate the ultrasound contrast-enhanced MRI and high intensity focused ultrasound for assessment （HIFU） ablation treatment of uterine fibroids. Methods A retrospective analysis of our hospital 60 cases of HIFU treatment of uterine fibroids （myoma 60） clinical medical records, and before and after treatment 1 d respectively MRI, ultrasound imaging. Statistical two sets of image quality scores before and after treatment fibroid volume and so on. Results Enhanced MRI image quality score, patients without perfusion volume and average ablation rate was （3.9 ±0.3） points, （81.9 ± 82.7） cms, （80.7± 18.4）% and ultrasound contrast （2.0± 0.7） points , （65.7 ± 66.1） cm^3, （71.5±19.4）%, the difference was statisticaIly significant, P〈0.05, enhanced MRI fibroids total score of 114 points image display ultrasound contrast significantly higher than 62 points, the difference was statistically significant, P〈0.05. Applications enhanced MRI scan can clearly show the relationship between fibroids border, size and with the surrounding tissue; however ultrasound contrast display blurry boundary, 10 patients could not be determined fibroids border. Conclusion Enhanced MRI can better assess the extent of HIEU ablation treatment of uterine fibroids, thus providing a strong basis for the selection of clinical prognosis and treatment options.
