Towards defining muscular regions of interest from axial magnetic resonance imaging with anatomical cross-reference: A scoping review of lateral hip musculature

Introduction: Measures of hip muscle morphology and composition (e.g., size fatty infiltration) are possible with magnetic resonance imaging (MRI). Standardised protocols or guidelines do not exist for evaluation characteristics, hindering reliable valid inter-study analysis. This scoping review aimed to collate synthesise MRI methods measuring lateral infiltration inform the future development standardised protocols. Methods: Five electronic databases (Medline, CINAHL, Embase, SportsDISCUS AMED) were searched. Healthy musculoskeletal pain populations that used assess included. Lateral muscles interest included tensor fascia late (TFL), gluteus maximus, medius, minimus. Data on parameters, axial slice location, infiltrate measures collected analysed. Cross referencing anatomical locations made between E-12 plastinate sections. Results: From 2692 identified publications, 79 studies contributed data volume (n=31), cross sectional area (CSA) (n=24), (n=40). Heterogeneity was observed parameters boundaries scrutinizing infiltration. Seven single level slices provided consistent CSA measurement, including three both maximus TFL, four medius For assessment infiltration, six two each gluteal muscles. Discussion: Several levels MR facilitate at hip, providing basis accurate synthesis improvements in validity analyses. Further into whole required further optimise methodological assessment. Impact application field: work establishes platform musculature will aid examination conditions around joint.
