Estimation of individual thigh muscle volumes from a single-slice muscle cross-sectional area and muscle thickness using magnetic resonance imaging in patients with knee osteoarthritis

Abstract

These simple methods could be applied in prospective research with a larger number of patients with KOA.

Quantifying skeletal muscle volume and shape in humans using MRI: A systematic review of validity and reliability

“…The primary aim of seventeen articles was to determine the metrological properties of a measurement technique. Ten articles had a score above 70/100 [9,27,28,45–51], fifteen articles had a score between 60 and 70/100 [25,26,52–64] and five articles had a score below 60/100 [29,65–68]. Details of the scores of each article are provided in S2 Table.…”

“…The articles included primarily focused on segmentation techniques. Manual techniques (including slice by slice cross sectional area (CSA) segmentation, segmentation of CSA in a reduced number of slice(s), segmentation of CSA on one slice and muscle length use) were evaluated in twenty-four articles [9,25–28,45–58,60–64] and partially or completely automatic segmentation techniques (deformation of a parametric specific object, semi-automated and automated atlas-based, image-based and shape-based, atlas-based and statistical shape-based, and interactive-segmentation using shape priors and statistical shape modelling methods) were evaluated in ten articles [27,29,48,53,59,64–68].…”

“…Muscle volume was evaluated in twenty-six articles [9,25–28,45–54,56–64,66,68], changes in muscle volume were evaluated in three articles [26,50,55] and 3D shapes were evaluated in seven articles [29,48,59,64,65,67,68].…”

“…Seventeen articles included only healthy subjects [26,27,45–50,52,53,57–60,62,64,67] and six included subjects with a muscular pathology of which five were on adults with: low back pain, total unilateral arthroplasty, anterior cruciate ligament reconstruction, chronic obstructive pulmonary disease or knee osteoarthritis [9,28,61,63,65]; the fifth article was on children with cerebral palsy [51]. Three articles evaluated cadavers [25,54,56].…”

“…Forty different muscles were examined: upper limb muscles were assessed in six articles [25,29,50,54,56,62] and lower limb muscles in twenty-four articles [9,26–28,45–49,51–53,55,57–61,63–68]. The rectus femoris muscle was the most frequently evaluated (n = 13 articles).…”
