Magnetic resonance imaging (MRI) is possible only because of some very advanced technology and the skills of some highly-trained specialists. An MRI is much more complex than an X-ray or CT scan, for example, and there are some built-in reasons why MRIs will always be more expensive than other imaging techniques.
Subsequently, Where is the lumbar spine located? Your lumbar spine consists of the five bones (vertebra) in your lower back. Your lumbar vertebrae, known as L1 to L5, are the largest of your entire spine. Your lumbar spine is located below your 12 chest (thoracic) vertebra and above the five fused bones that make up your triangular-shaped sacrum bone.
Is MRI harmful? Risks of the Procedure Because radiation is not used, there is no risk of exposure to radiation during an MRI procedure. However, due to the use of the strong magnet, MRI cannot be performed on patients with: Implanted pacemakers. Intracranial aneurysm clips.
Yet, What is the side effect of MRI? The magnetic fields that change with time create loud knocking noises which may harm hearing if adequate ear protection is not used. They may also cause peripheral muscle or nerve stimulation that may feel like a twitching sensation. The radiofrequency energy used during the MRI scan could lead to heating of the body.
Why is MRI so loud? The MRI machine uses a combination of a strong magnet, radio transmitter and receiver. When the sequences are performed, electric current is sent through a coiled wire-an electromagnet. The switching of the currents causes the coils to expand making loud clicking sounds.
Is lumbar spine pain serious?
