Publikováno v: EJNMMI Physics, Vol 8, Iss 1, Pp 1-16 (2021)

Abstract Background Accurate quantification of radioactivity, measured by an integrated positron emission tomography (PET) and magnetic resonance imaging (MRI) system, is still a challenge. One aspect of such a challenge is to correct for the hardwar

MRI T2 and T1ρ relaxation in patients at risk for knee osteoarthritis: a systematic review and meta-analysis

Autor: Hayden F. Atkinson, Trevor B. Birmingham, Rebecca F. Moyer, Daniel Yacoub, Lauren E. Kanko, Dianne M. Bryant, Jonathan D. Thiessen, R. Terry Thompson

Publikováno v: BMC Musculoskeletal Disorders, Vol 20, Iss 1, Pp 1-18 (2019)

Abstract Background Magnetic resonance imaging (MRI) T2 and T1ρ relaxation are increasingly being proposed as imaging biomarkers potentially capable of detecting biochemical changes in articular cartilage before structural changes are evident. We ai
