[|Human|] What does this mean, Delayed planar images demonstrate mild uptake within the left L4-L5 region.SPECT -CT of the lumbar spine was obtained. This demonstrates no evidence of disc uptake however, there is very mild facet uptake at L4-L5 on the left. Hypertrophic facet degenerative changes seen in the region on nondiagnostic CT.
[|AI|]  Hi, Thanks for writing in. The uptake seen at L4 - L5 with hypertrophic facet changes are indicative of degeneration because of aging. Such changes occur with age and can cause mild lower back pain and spasm of muscles. A pinched nerve can also arise from this condition. You must consult a neurologist and probably also get a lumbar spine MRI scan done to know if there is a disc herniation or nerve impingement which is not seen clearly on SPENT CT should you experience severe pain in the region. It is important to know why you got a spent CT done and if it is related to any cancerous condition for which you are taking treatment. There is no serious concern for the above findings.
