The vacuum phenomenon in spinal imaging. In this study, metagenomic analysis was used to find out the distribution characteristics of ARGs in two WWTPs equipped with the same D-Type fiber filters. Gas production or "vacuum phenomenon" in the intervertebral space may be a byproduct of disc degeneration. A vacuum phenomenon is caused by negative pressure within the joint due to the position of the patient, which results in the accumulation of nitrogengas. The vacuum phenomenon (VP) refers to collection of gas within the joint space . - Severe degenerative changes with discogenic sclerosis, vacuum phenomenon, large osteophytes & disc space narrowing - Low T2 signal & lack of enhancement in disc & surrounding tissues - Facet joints may be affected Abnormal laxity of the joint capsule can be demonstrated in CT as an abnormally wide joint space or as gas in the facet joint (vacuum joint).
