BACKGROUND AND PURPOSE: Normative age-related decline in paravertebral muscle
quality is important for reference to disease and risk identification in patients. We aimed to …

Study Design. Retrospective chart analysis of 199 individuals aged 18 to 80 years
scheduled for lumbar spine surgery. Objective. The purpose of this study was to quantify …

Purpose To determine the association of paraspinal muscles and psoas relative cross-
sectional area (RCSA) and fat signal fraction (FSF) with sex, age, and intervertebral disc …

Study Design. Cross-sectional. Objective. We quantified fatty infiltration (FI) geography of the
lumbar spine to identify whether demographics, temporal low back pain (LBP), and disability …

Background There is increasing interest in paravertebral muscle composition as a potential
prognostic and diagnostic element in lumbar spine health. As a consequence, it is becoming …

Background Fatty infiltration, as a result of aging, is an essential biomarker of muscle
degeneration. This research aimed to investigate the age-dependent change of fatty …

Background The spinal column including its vertebrae and disks has been well examined
and extensively reported in relation to age-aggregated degeneration. In contrast …

Abstract Background Context Spinal degeneration can occur not only in the bone and disc
but also in muscles. Fatty infiltration (FI) and decreased volume have been described as …

This narrative review investigated imaging parameters of the paraspinal muscles and their
association with spinal degenerative features and low back pain (LBP) found in the …

Purpose: To prospectively evaluate the fat content of paraspinal muscles by using proton
magnetic resonance (MR) spectroscopy in patients with chronic low back pain (LBP) and in …
