The aim of this study was to characterize the lumbar paravertebral muscles (multifidus, longissimus, ilio-costalis, quadratuslumborum) using diffusion tensor imaging (DTI). Specifically, tensor eigenvalues (位1, 位2, 位3), mean diffusivity (MD), fractional anisotropy (FA), and relative dispersion...
The signal intensity of the multifidus muscles on MRI was retrospectively measured by two radiologists, and the fat content of patients with unilateral articular lumbar disc herniation was visually graded using a 5-point grading system. The temporal and contralateral performance was compared and the ...
Myoelectric activity, lumbar extensor strength, and cross-sectional magnetic resonance imaging appearance of the lumbar paraspinal extensor muscles was assessed at the beginning and end of the program. Initial baseline and final extensor strength measurements were done isometrically at seven points through...
Magnetic resonance imaging (MRI) is a highly sensitive and specific imaging technique that yields comprehensive images of the structure, function, and composition of tissues in the body.1Balasubramanya R, Selvarajan SK.

up in patients who had been treated for sciatica and lumbar-disk herniation did not distinguish between those with a favorable outcome and those with an unfavorable outcome. Moreover, they stated that further research is needed to evaluate the value of MRI in clinical decision-making for patients...

who reported a 40% reduction in measurement time for lumbar spine MRI while maintaining image quality in a prospective multicenter study [27]. In general, due to the inherently higher signal-to-noise ratios at 1.5 T and 3 T, much higher acceleration factors can be used than 0.55 T...
so it was impossible for us to calculate subcutaneous fat area. Instead, perianal fat thickness was applied. Finally, most pelvic CT or MRI images didn’t reach the height of umbilical level or the third lumbar vertebrae level, which was often used in measuring the abdominal fat distribution....
The need for long-term cohort studies on this matter has been addressed1. Previous studies have shown that muscle mass decreases with age10,11. The CSA of the paraspinal muscles also tends to decrease with age, especially among the elderly, and lumbar muscle CSA is larger among men than ...
