Semiquantitative assessment of skeletal response to enzyme replacement therapy for Gaucher's disease using the bone marrow burden score

Abstract

OBJECTIVE: The purpose of this study was to evaluate the use of a recently described assessment tool to quantify bone marrow response to enzyme replacement therapy in a cohort of adult patients with type 1 Gaucher's disease. MATERIALS AND METHODS: Serial MR images of the femurs, lumbar spine, or both of 57 subjects with a diagnosis of Gaucher's disease, 44 of whom were being treated with enzyme replacement therapy, were evaluated by two musculoskeletal radiologists using the bone marrow burden (BMB) scoring system. This system gives a score out of a possible 8 for the lumbar spine and a score out of a possible 8 for the femurs, so the total BMB score is out of 16. RESULTS: The mean total BMB..
