頭部・脊椎領域の単純X線写真

Head and Spine X-Rays: Clinical Value and Practical Use

頭部および脊椎領域における単純写真の撮影機会は減少しており，その臨床的意義は限定的である。しかし，単純写真は全体像の把握に有用であり，血液疾患，薬剤性疾患，骨代謝性疾患，骨系統疾患，先天奇形，骨腫瘍などにおいては，いまだ単純写真には高い診断的価値がある。本論では，偶発的に発見され得るものを含め，単純写真が診断の契機となる代表的疾患を概説する。

Abstract

Radiographs of the head and spine are now obtained less frequently, and their clinical significance has become limited. Nevertheless, they remains useful for the overall assessment of the cranial and spinal structures. In particular, X-rays still provide high diagnostic value in hematologic disorders, drug-induced conditions, metabolic bone diseases, skeletal dysplasia, congenital anomalies, and bone tumors. This article reviews representative diseases in which a radiography can serve as the initial clue for diagnosis, including conditions discovered incidentally.
