radiation-induced lung injury
acute(1-3months)
impaired gas exchange due to exudative alveolitis → ☆hyaline membrane formation, pneumocyte sloughing(slúː)
chronic(6-12months)
radiation fibrosis(dense fibrous bands) results in decreased lung volume and dilated bronchi and bronchioles(ie traction bronchiectasis)
(predisposition to chronic infections)

late stage radiation dermatitis
(months to years, acute<90 days after radiotherapy)
fibrosis= ☆homogenization of dermal collagen, vascular damage→ chronic hypoxia and ulceration, ☆abnormal dilatied microvasculature(ie telangiectasias)

腎障害をもつ患者へのガドリニウム造影剤使用
●腎性全身性線維症（NSF：nephrogenic systemic fibrosis）
重篤な腎障害をもつ患者へのガドリニウム造影剤使用に関連して発症する．ガドリニウム投与から数ヵ月，数年の期間を経て，全身性かつ左右対称性の皮膚の膨張や硬化が顕著にみられ，進行すると四肢関節の拘縮を呈する．透析によってもガドリニウム造影剤は除去できないためNSFのリスクは低下しない．
