主要方法:
- 在怀疑PAS的美国初步评估后,对41例被转诊MRI的病例进行回顾性分析,超过13年.
- 评估MRI准确性 (灵敏度,特异性) 在诊断PAS.
- 仅使用美国和使用MRI的美国之间的诊断结果的比较.
主要成果:
- 确诊了11个PAS病例.
- 核磁共振扫描显示了PAS诊断的高准确性 (灵敏度为81.8%,特异性为86.6%).

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...
