[Diagnostic Imaging and Radiomics for Glioma]

Radiographic imaging enables minimally invasive observation of internal organs and is an indispensable medical technique for modern medicine. Just as histopathological findings reveal a lesion in the microscopic world, a radiographic image is an observation of the lesion from a macroscopic perspective. Since the discovery of X-rays, the progress of radiographic imaging technology has been remarkable. Radiographic images, which could only be expected to show structural images in the early days, are able to reveal brain functioning and are now anticipated to accomplish the qualitative diagnosis of lesions. However, clinicians will need to return to technical theory for critical evaluation from a neutral perspective. In this paper, we have summarized the "common knowledge," which is indispensable in radiographical diagnosis of glioma, emphasizing the theory of basic neuroradiography and predict the "near future" of radiological images of glioma imaging.
