To diagnose diseases in the cervical spine, many patients are prescribed magnetic resonance imaging of the cervical spine without injection of magnetic contrast. This is a diagnostic method with a very high accuracy and safety rate, so it is widely applied today.

Magnetic resonance imaging is an imaging technique that does not use X-rays, is non-invasive, and does not contain ionizing radiation. It is the most effective method when compared with other imaging methods because of its ability to clearly and detailed evaluation of the cervical spine. In particular, this method can also help doctors assess the condition of the spinal cord and nerves (something other diagnostic techniques cannot do).
Magnetic resonance imaging can evaluate areas that are hidden by bone or difficult to see in other imaging methods. This is also a particularly useful technique in diagnosing compression, acute myelitis (clinical manifestations of paralysis or numbness). Spinal diseases such as damage to discs, vertebral bodies, spinal cord and soft tissues around the spine,... can all be diagnosed accurately by MRI.

In case the patient presents with severe arm pain, unresponsive to long-term treatments; In case the patient has long-term neck pain, shoulder pain, poor response to treatment;

Help detect disc diseases such as degenerative, bulging or herniated discs; Detection and evaluation of congenital malformations of the spinal cord; Detecting multiple sclerosis or diseases of the spinal nerves; Diagnosis of sensory disorders such as numbness, tingling or paresthesia, ... in the shoulder and neck, hands,...; Help the doctor assess the condition of the cervical spine before surgery; Help doctors accurately assess the patient's post-surgery condition of the cervical spine, especially detecting new abnormalities that occur after surgery; Assess for signs of suspected vertebral fracture or evaluate for old vertebral fractures; Diagnosis and assessment of spinal tuberculosis (need to combine with injection of contrast agent to make lesions more obvious); Diagnosis or evaluation of cervical spine injury; Diagnosis of cancer or tumor in the cervical spine (need to combine with injection of contrast agent to make the lesion more visible).

3.1 Absolute contraindications Severe patients, requiring resuscitation equipment on the body; People who have been implanted with electronic devices on the body such as cochlear implants, automatic drug pumping devices under the skin, pacemakers, anti-vibration machines,...; People with metal clips in the blood vessels, intracranial or orbit for less than 6 months; Pregnant women under 12 weeks of age. Pregnant women over 12 weeks can have an MRI without affecting the fetus.

3.2 Relative contraindications Patients with metal surgical clamps over 6 months: Using metal in orthopedic surgery, orthopedic surgery, fitting dentures or braces; Young patients, hyperactive or people weighing over 250kg; People who are afraid of the dark or afraid of being alone.

4.1 Preparation of Implementation Personnel: Including specialists, nursing assistants and imaging technicians; Technical facilities: Including MRI machine; film, film printers and image storage systems; Patient: Received detailed explanation of necessary technical information by the doctor; checked for contraindications; no need to fast; change the clothes of the magnetic resonance imaging room, remove the items on the list of contraindications; bring the doctor's request for magnetic resonance imaging or medical records if available; 4.2 Conducting MRI of cervical spine Patient position: Lying supine on the scanning table; Doctor's choice - position the receiver coil. Then, the doctor moves the table into the correct magnetic field of the magnetic resonance imaging machine and locates the imaging area; Location capture; Capture the T1W, T2W vertical and transverse T2W pulse sequences through the required position. Stir can be shot vertically if needed; At the end of the magnetic resonance imaging process, the medical staff removed the signal receiver coil and invited the patient out of the imaging room, waiting for the results; The technician will process the images, print the film and transfer the obtained images and data to the doctor; The doctor performs image analysis and makes a diagnosis.

4.3 Returning diagnostic results Magnetic resonance imaging results allow doctors to clearly observe anatomical structures of the cervical spine; Films can show images of damage caused by diseases in the cervical spine, if any; The doctor reads the injury and gives professional advice to the patient - family. 4.4 Possible complications and how to deal with the patient being scared or agitated: The doctor should encourage and comfort the patient; The patient is too scared and worried: The doctor can give the patient a sedative under the supervision of the anesthesiologist. If the patient strictly follows the safety instructions of the doctor and technician during the cervical spine magnetic resonance imaging procedure, the risk of this technique is almost zero. Therefore, this is a very good technique. Because it is safe, patients and relatives do not need to worry too much when they are assigned to perform this imaging method.
