Whole-body MRI vs bone scintigraphy in the staging of Ewing sarcoma of bone: a 12-year single-institution review

摘要: To compare whole-body MRI (WB-MRI) at 1.5/3T and bone scintigraphy in the skeletal staging of Ewing sarcoma (ES) bone. All patients with a histological diagnosis ES between 2007 2018 were retrospectively reviewed. The analysis included gender, mean age, distribution, prevalence metastases on WB-MRI scintigraphy. study group comprised 182 age 18.0 years (range 2–56 years), 126 males 56 females. Skeletal detected overall 30 (16.5%), 23 96 (24%) who underwent WB-MRI, 20 118 (16.9%) Of 71 both scintigraphy, modalities 13 (18.3%), while 4 patients, identified alone. There no whom studies, showed greater number metastatic foci 10 (76.9%). However, was superior to detecting skull vault lesions, but did show false-positive results around long growth plates. is more sensitive than bone, exception metastases. Consideration should be given replacing WB-MRI. • Whole-body bone. can safely replace for skeleton, acknowledgement possibility missing clinically occult metastasis.
