摘要目的脑实质多频MR弹性成像(MMRE)在视神经脊髓炎谱系疾病(NMOSD)病人与年龄匹配健康对照组(HC)中的应用研究。方法 15例NMOSD病人与17名年龄和性别匹配的健康对照者进行MMRE检查。通过30~60 Hz的7个谐波激励频率、同步反转全波场数据,采用1.9 mm各向同性
Abstract Objective To investigate the clinical application of brain real-time multi-frequency MR elastography (MMRE) in patients with optic neuromyelitis spectrum (NMOSD) and age-matched healthy controls (HC). Methods 15 patients with NMOSD and 17 age and sex matched healthy controls were examined by MMRE. Through the seven harmonic excitation frequencies of 30 ~ 60 Hz, the full-wavefield data are inverted synchronously, and the isotropy of 1.9 mm
