Abstract:
PurposeTo investigate the physical characteristics of the lumbar bone marrow fat content by analyzing the correlation of the lumbar bone marrow fat content with age, gender, body mass index (BMI) and waist circumference. It may be helpful to deepen the understanding the occurrence regularity of osteoporosis. Materials and Methods A total of 144 subjects were recruited including both healthy volunteers and the patients with chronic low back pain. The height, weight and waist circumference were measured, and the body mass index was calculated. All the subjects took spectroscopy sequence at the third lumber vertebra with single-voxel point resolved spectroscopy (PRESS) method. Lipid (1.3 ppm) to water (4.67 ppm) ratio (LWR) and lipid fractions (FF%) were measured. LWR and FF% of L3 were compared among the patients with different gender, age, BMI and waist circumference. The correlation of LWR and FF% of L3 and age were analyzed.Results The LWR and FF% of L3 showed no signiifcant difference between the male and female (t=-0.267 and-0.993,P>0.05). There was statistical difference of LWR and FF% among the different age groups (F=3.723 and 5.478,P<0.05). LWR and FF% of female in 61-70 year-old group showed signiifcant higher than that in 20-30, 31-40, 41-50 and 51-60 year-old group (P<0.05). FF% of L3 in 20-30 year-old female group showed signiifcant lower than that in >70 year-old group (P<0.05). LWR of L3 for both male and female in 60-70 year-old group also showed signiifcant higher than that in 20-30, 31-40, 41-50 and 51-60 year-old group (P<0.05). FF% for both male and female in 20-30 year-old group showed signiifcant lower than that in 31-40, 41-50, 51-60, 61-70 and>70 year-old group (P<0.05). FF% of 61-70 year-old group was signiifcant different from that in 31-40, 41-50, 51-60 year-old group (P<0.05). The LWR and FF% of L3 showed no signiifcant difference between the different BMI groups and waist circumference groups (P>0.05). Age was positive correlated with FF% of L3 (r=0.321,P<0.05).Conclusion The lumbar bone marrow fat content is correlated with age, but is not correlated with gender, BMI and waist circumference.
