- 医疗成像医学成像
- 放射学 放射学是一门学科.
- 神经成像是一种神经成像.
背景情况:
- 新生儿臂成像受到长时间的扫描时间和运动器件的挑战.
- 需要加速成像技术来提高诊断准确度和成功率.
研究的目的:
- 为了评估压缩灵敏度编码 (CS) 新生儿手臂成像.
- 在图像质量和扫描时间方面,将CS与传统的灵敏度编码 (SENSE) 进行比较.
主要方法:
- 45名怀疑有臂损伤的新生儿使用CS和SENSE3D神经视图序列进行了MRI.
- 平行收购加速系数为SENSE的1.3和CS的6 .
- 图像质量由两个儿科放射科医生进行了定量 (SNR,CNR) 和定性评估.
主要成果:
- CS将获取时间缩短了大约30% (3:36比5:08分钟).
- 在CS和SENSE之间没有观察到SNR或神经到肌肉CNR的显著差异.
- 放射科医生的定性评估显示,CS和SENSE之间的图像质量可比,评价者之间有很强的一致性.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
942
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Spinal Nerves: Plexus I
1.3K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
