Fatty Degeneration of the Paraspinal Muscle in Patients With Degenerative Lumbar Kyphosis

Abstract

Quantitative analysis using magnetic resonance imaging and computed tomography scanning showed differences in paraspinal muscle volume and fatty degeneration between patients with DLK and healthy volunteers. This evaluation method may be useful for measuring the extent of paraspinal muscle degeneration.

Magnetic resonance spectroscopic analysis of multifidus muscles lipid content and association with spinopelvic malalignment in chronic low back pain

“…6,24,25 We previously reported that IMCLs using MRS analysis in the Mm of patients with CLBP were significantly higher than in asymptomatic volunteers. 26 Some reports have described the associations of spinopelvic alignment with LBP [27][28][29] and fatty atrophy of Mm; 7,30 however, the association of IMCLs and EMCLs with spinopelvic alignment in patients with CLBP remains unclear. The aims of the present study were to analyze IMCLs and EMCLs of the Mm using MRS in CLBP and control groups and to identify possible correlations with spinopelvic alignment.…”

Cross‐sectional area and fat content in dachshund epaxial muscles: an MRI and CT reliability study

“…By contrast, a human study on paraspinal muscle size and fat infiltration showed higher intrarater (0.910) and inter-rater reliability (0.890) for MRI than for CT (intrarater reliability 0.780, inter-rater reliability 0.650). 14 Not surprisingly the CSA is more reliably measured by MRI than by CT in human subjects because human muscles are larger and high-field scanners (1.5–3.0 T) are generally used. 14 22 …”

“…Atrophy (decreased CSA) and fat infiltration are two signs of muscle degeneration that can be evaluated with MRI and CT. 7–9 The CSA measured by MRI and CT is determined by the total quantity of muscle fibres and provides an objective measure of muscle size. 14 Fat infiltration may decrease the contractile ability of a muscle when muscle fibres are replaced by non-contractile fat tissue, resulting in altered muscle function. 9 Intramuscular fat is reliably quantified using the signal intensity obtained by MRI.…”

Radiology methods of the sarcopenia diagnosis

“…Имеются также данные об оценке массы паравертебральных мышц как на протяжении всего поясничного отдела позвоночника, так и на уровне отдельных межпозвонковых дисков [19,20]. Наибольшее распространение в количественной оценке мышечной ткани получил подход с определением площади всех поперечнополосатых мышц, входящих в зону сканирования на уровне LIII позвонка (m. psoas major, m. erector spinae, m. quadratus lumborum, m. obliquus externus abdominis, m. obliquus internus abdominis, m. transversus abdominis, m. rectus abdominis).…”
