由于年龄的因素,老年人肺部疾病有比较鲜明的自身特点,其发生、发展和影像学表现不同于其他年龄组。近年来,医学影像设备发展迅速,特别是多排螺旋CT和MR的发展,对疾病的诊断和治疗评价提供了更丰富的影像学信息,主要表现在普通X线检查图像数字化,CT检查图像薄层化和快速化,MR检查信息功能化。因此,医学影像学发展为形态影像学、功能影像学和分子影像学三大方面,这不仅为 Due to the age factor, elderly patients with lung disease have their own distinct features. Their occurrence, development and imaging manifestations are different from those of other age groups. In recent years, the rapid development of medical imaging equipment, especially the development of multi-slice spiral CT and MR, provides a richer imaging information for the diagnosis and treatment evaluation of diseases, which is mainly manifested in digitization of common X-ray examination images, CT examination of image thinning Layered and fast, MR inspection information functional. Therefore, the development of medical imaging morphomorphology, functional imaging and molecular imaging of the three major aspects, not only for
