Abstract

Objective: To study the feasibility of magnetic resonance elastography (MRE) for the evaluation of myoma uteri in Thai patients. Materials and Methods: A prospective descriptive study was conducted between September 2020 and October 2021. Twenty-six myoma uteri patients were performed in a 3.0-Tesla MRI scanner, added with a pneumatic system generating mechanical waves. For the MRE assessment, the number of acquired slices, mean stiffness with standard deviation (SD), minimum, and maximum stiffnesses (kPa) were recorded. Results: The mean stiffness of the myoma uteri was 3.02 kPa (range 1.83 to 5.06, SD 0.79). Their volume ranged from 56.24 to 716.35 cm³ (mean 237.74, SD 187.63. The proportion of lesions ranged from 31.87% to 74.36% of the whole uterus (mean 44.94, SD 16.98). Conclusion: Uterine MRE is a feasible diagnostic tool for studying the tissue stiffness of the myoma uteri, which is higher than normal uterine tissue. The mean stiffness of Thai patient myoma uteri was lower than other ethnicities. Keywords: Myoma uteri; Uterine fibroid; Uterine leiomyoma; MRE; Tissue stiffness

子宫肌瘤:泰国患者磁共振弹性成像的硬度:一项初步研究

目的:探讨磁共振弹性成像(MRE)评价泰国子宫肌瘤的可行性。材料和方法:一项前瞻性描述性研究于2020年9月至2021年10月进行。26例子宫肌瘤患者在3.0特斯拉MRI扫描仪上进行了检查，并增加了产生机械波的气动系统。对于MRE评估，记录获得的切片数、平均标准差(SD)、最小和最大刚度(kPa)。结果:子宫肌瘤的平均硬度为3.02 kPa(范围1.83 ~ 5.06,SD 0.79)。体积范围为56.24 ~ 716.35 cm³(平均237.74 cm³，标准差187.63 cm³)。病变占全子宫的比例为31.87% ~ 74.36%(平均44.94%，标准差16.98)。结论:子宫磁振造影是研究子宫肌瘤组织硬度高于正常子宫组织的一种可行的诊断工具。泰国患者子宫肌瘤的平均僵硬度低于其他民族。关键词:子宫肌瘤;子宫肌瘤;子宫平滑肌瘤;绝笔;组织刚度
