금속이 삽입된 수술 부위에 발생한 염증 부위에서 18F-Sodium Fluoride 뼈 양전자 방출 단층촬영 기법을 사용한 염증의 조기 발견 및 치료 평가: 증례 보고

Abstract

We report a case of a 76-year-old woman with elevated serum C-reactive protein levels for two weeks after spinal surgery. 99mTc-labeled white blood cell scan and dual 18F-sodium-fluoride (18F-NaF) bone positron emission tomography/computed tomography (PET/CT) were used to detect the site of inflammation. Using non-attenuation corrected images, soft tissue inflammation was detected without metal artifact. Antibiotic treatment attenuated inflammation as seen in an early-phase scan using follow-up 18F-NaF bone PET/CT. This case demonstrates the role of 18FNaF bone PET/CT in the detection of inflammation sites, and can be used to evaluate treatment response in patients with metallic implants.
