Codari M, Zanardo M, di Sabato ME, et al. - In order to summarize the role of MRI as a noninvasive method for the recognition of in vivo surrogate biomarker of sarcopenia, a systematic review 69 records recognized through search query was done. The sample size varied from nine to 284 individuals, for a total of 1,706 recruited individuals. The proposed biomarkers were evaluated via various MRI sequences for distinctive body regions in different individual/patient cohorts, pointing toward a lack of standardization on this issue. Further studies should examine and contrast the performance of proposed MRI biomarkers for sarcopenia characterization and quantification using a standardized experimental setup.
