Lumbar MRI usually takes 10-20 minutes to complete. Lumbar MRI is usually used for the diagnosis of lumbar disc herniation, lumbar spinal stenosis, lumbar spine malignancy and other diseases. When considering lumbar spine MRI, it should be noted that no metal objects should be worn on the body, and the time for each examination is mostly 10-20 minutes. However, due to the closed space, if the patient has claustrophobia, it will have a certain degree of psychological impact. With the development of science and technology, MRI is gradually becoming open, and the psychological impact of patients will be significantly reduced. If there are lumbar spine related diseases, MRI of the lumbar spine should be considered, which can clearly show the lumbar spine lesions.
