概括

扩散张力成像 (DTI) 可以检测肌肉,类似于运动单元MRI (MUMRI). 在健康个体的下腿上,纹更常见,更大,随着时间的推移分布一致.

科学领域:

神经成像是一种神经成像.
肌肉骨的MRI是指肌肉骨的MRI.
神经学神经学

背景情况:

结在运动神经元疾病中很常见,但在健康个体中也会发生.
了解结的强度和分布至关重要.
运动单元MRI (MUMRI) 可以评估结,但未被广泛使用.

研究的目的:

评估扩散张力成像 (DTI) 是否可以检测出.
将DTI的灵敏度和精度与MUMRI进行比较.
为了确定健康个体下肢的结强度和分布.

主要方法:

在健康受试者的上腿肌肉中对MUMRI和DTI进行系统比较 (n=5).
使用DTI.对健康受试者 (n=30) 的下肢肌肉中带强度和分布的回顾性分析.
为低信号噪声比率和DTI中的信号变异性进行校正.

主要成果:

DTI的灵敏度 (75%) 和精度 (80%) 与MUMRI相似.
在健康受试者的下腿部比上腿部更为普遍和更大.
在8个月的时间里,囊分布保持一致.

结论:

肌肉DTI是一种可行的方法来检测结.
在现有的MRI数据集中,DTI可以进行囊的回顾性分析.
如果已经获得了DTI,可能会减少对专门的MUMRI研究的需求.

关键词:

扩散张力成像的成像方法这种方式是fasciculation. fasciculation.磁共振成像技术的使用发动机单元的发动机单元.这是骨肌肉的骨架肌肉.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
