The use of fluorine-18-fluorodeoxyglucose-positron emission tomography/computed tomography as an effective method for staging in dogs with primary appendicular osteosarcoma.

摘要: Fluorine-18-fluorodeoxyglucose (18 F-FDG) positron emission tomography/computed tomography (PET/CT) has been utilized in veterinary medicine to improve the detection and characterization of primary, recurrent, secondary neoplasms; but its use as a staging tool for dogs diagnosed with appendicular osteosarcoma not published. The purpose this retrospective, case series, descriptive study was detail 18 F-FDG PET/CT population osteosarcoma, report rate neoplastic lesions, compare findings published rates other historically used imaging modalities. Seventy-one client-owned confirmed diagnosis staged whole-body scan near time initial were included. Each re-evaluated malignancy distinct from primary disease entity based on collective qualitative quantitative assessment uptake, CT appearance, contrast enhancement characteristics. Following re-evaluation each study, information pertaining tissue sampling performed identified lesions retrieved medical record when available. Staging 17 71 (23.9%) 12 (16.3%) high suspicion or confirmation metastatic comorbid malignant neoplasm respectively, eight (11.3%) having both lesions. results are suggestive that is effective identifying osseous soft afflicted yielding an increased all compared those previously reported skeletal scintigraphy CT.
