グリオーマの画像診断とradiomics

Diagnostic Imaging and Radiomics for Glioma

Point

・グリオーマ診療でCTやMRIなどの放射線画像を正しく理解するためにはある程度の基礎・理論を知っておくことが望まれる．

・定性画像と定量画像それぞれの利点と欠点，ならびに撮影条件の基本をおさえよう．

・Radiomicsなどの新規技術はこれからもますます発展すると思われるが，過度の期待は禁物である．

　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.
