MRI DORSAL LUMBER SPINE

Magnetic Resonance Imaging (MRI) of the dorsal lumbar spine is a meticulous clinical evaluation of the thoracic (dorsal) and lumbar spine portions. It employs potent magnets and radio waves to produce precise images of the vertebral column, intervertebral spaces, spinal cord, and other delicate structures in the vicinity.  

What is MRI Dorsal Lumbar Spine? 

With MRI, the dorsal (thoracic) and lumbar regions of the spine can be viewed using inductively coupled radiation to produce sound waves at varying frequencies. MRI is particularly useful in visualizing soft tissues because of the high level of contrast between tissues, particularly in the spinal cord, intervertebral discs, and nerve roots. 

Types of MRI Dorsal Lumbar Spine 

• Conventional MRI: It is the standard imaging technique which provide details of the spine. 
• Contrast-Enhanced MRI: This is done with gadolinium bound contrast to enhance visibility of tumours and other infections. 
• Functional MRI (fMRI): This type focuses on measuring the response of the spinal cord to different stimuli. 

• Posture of Bones 
• Disks 
• Spinal Cord Shape and Nerve Root Shape 
• Lesions, tumours or infections presence 
• Opening of neural foramen and spinal canal 

• Tumours or tumour-like lesions of the spinal column 
• Disc displacement or degenerative disc disease 
• Compression of the spinal cord or nerves (myelopathy/radiculopathy) 
• Evaluation after surgery peripheral) 
• Spondylarthrosis inflammatory conditions 

When and Who Needs an MRI Dorsal Lumbar Spine? 

Indications:  

• Ongoing and chronic mid or lower back pain 
• Neurological symptoms such as weakness, tingling or numbness 
• Possible chances of spinal cord or nerve root compression 
• In case of multiple sclerosis or any other form of demyelinating disease 
• Evaluation of congenital or degenerative changes in the spine 

Patient Demographics:  

• Adults with chronic back pain accompanied by sciatica 
• Patients with prior history of spinal tumours or infections 
• People suffering from unexplainable neurological deficits 

Benefits of Taking the Test

• Non-invasive procedure with no exposure to radiation 
• Captured images of soft tissues have excellent clarity 
• Identification of spinal disorders is uncomplicated 
• Pivotal in planning operations and conducting assessments after surgery 

Illnesses Diagnosed with MRI Dorsal Lumbar Spine

• Disc herniation 
• Osteochondrosis with intervertebral foraminal stenosis  
• Spinal cord neoplasms or cystic lesions  
• Cancers (osteomyelitis, discitis) 
• Demyelination processes like multiple sclerosis 
• Compression of the nerve root or sciatica

• Leave watches, rings and electronic gadgets at home 
• Don comfortable attire that does not restrict movement 
• Inform the technologist about certain devices on the body, pregnancy 
• Removal of undergarments and immobilization who have with the use of contrast, fasting may be needed 

Pre-requisite 

• Absence of allergy to contrast media (for MRI with contrast) 
• Preferable to have medication with sedatives because of anxiety or claustrophobia 

Best Time to Take the MRI Dorsal Lumbar Spine 

• Anytime, as long as directed by their physician  
• Restrict booking MRI to ensure no appearances 

Eligibility 

• Almost always safe with the exception of patients with metal implants or pacemakers. 

Procedure for Taking an MRI Dorsal Lumbar Spine 

• The patient lies on an MRI table. 
• A coil is fitted around the patient's thoracic and lumbar region.  
• The machine captures images using magnetic fields and radio waves. 
• The procedure lasts between 30 - 60 minutes.  
• If required, a Contrasting agent may be injected. 

Caution Before Taking the Test 

• The Radiologist should be informed of pregnancy, any disorders of the kidneys, or metal implants.  
• Do not move from your position for best results during the scan.
