KKKoichiro Kaneko YMYui Maekawa SNSayaka Nemoto

Key Points

The study aims to evaluate the efficacy of FDG-PET/CT imaging in assessing sarcoidosis, particularly cardiac lesions.
Utilized static FDG-PET/CT for baseline evaluation, therapy effectiveness, and recurrence diagnosis.
Implemented dynamic FDG-PET imaging with semiconductor detection for clinical applications.
Analyzed differences in imaging results between cardiac and extrapulmonary lesions.
Static imaging is effective for assessing the activity of cardiac lesions.
Dynamic imaging may offer enhanced insights for various conditions, including cancer and inflammatory diseases.
Distinct metabolic activity patterns were observed between cardiac and extrapulmonary lesions.

Abstract

サルコイドーシスは，全身臓器に非乾酪性類上皮細胞肉芽腫を形成する疾患で，本邦では呼吸器病変，眼病変，心臓病変の頻度が高く，死亡例の多くは心臓病変に起因する．病変の糖代謝を反映するFDG PET／CT検査は，心臓病変の活動性評価において保険適用となっているが，一度に全身撮像を行うため，心外病変の評価にも適している．通常FDG投与約60分後より撮像するstatic画像を用いて，治療前評価，免疫抑制療法の効果判定，再発診断を行うが，半導体検出器を備えたPET／CT撮像機器の登場によりdynamic PET撮像が可能となり，がんや炎症性疾患への臨床応用が期待される．本稿ではサルコイドーシスにおける治療前のFDG-PET／CT所見，FDG高集積を呈する他疾患との鑑別，治療後の集積変化，予後に関して心臓病変，心臓外病変の相違を含めて概説し，当施設のdynamic FDG-PET／CTにおけるサルコイドーシスを含むいくつかの臨床的知見を紹介する．
