Disc herniation is one of the most common conditions of the lumbar spine.More and more people are suffering from this symptoms.Our study focused on fat infiltration of bilateral lumbar multifidus muscle in patients with lumbar disc herniation. Based on the IDEAI-IQ technology, proton density fat fraction of lumbar multifidus muscle is evaluted. The preliminary results show that the degree of fat infiltration in the lumbar spine protrusion is relatively higher in the herniated side than contralateral side.Our results can reflect the degree of fat infiltration quantitatively, which can be further expanded into the quantitative classification of different populations and different causes.
