골경화성 골전이를 동반한 유방암 환자에서 F-18 fluoride PET/CT의 유용성
Bone metastasis is an important factor for treatment and prognosis of breast cancer patients. Whole body bone scintigraphy can be used to evaluated bone metastases and also F-18 FDG PET/CT seems to exhibit high specificity and accuracy to detect skeletal metastases. However there is the limitation …

Improving Quantitative Treatment Response Monitoring With Deformable Image Registration
Quantitative imaging with 18F-FDG PET/CT has the potential to provide an in vivo assessment of response to radiotherapy (RT). However, comparing tissue tracer uptake in longitudinal studies is often confounded by variations in patient setup and potential treatment induced gross anatomic changes. …
