- 评估定量磁共振成像 (MRI) 帕金森症指数在区分PSP与MSA方面的有效性.
- 开发一种新的尺度 (PMS尺度) 来增强诊断歧视.
主要方法:
- 在PSP和MSA患者中计算了定量MRI测量,包括上大脑脚的宽度,第三心室的宽度,pons/mesencephalon (P/M) 比率和磁共振帕金森症指数 (MRPI).

01:24Magnetic 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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
