Magnetic resonance imaging (MRI) is a safe and painless research method, which is based on the principle of interaction of the magnetic field with the human body.
If the patient is a small child, then MRI for children can be performed to diagnose various diseases that are difficult or impossible to determine using x-rays or computed tomography.
In recent years, the use of magnetic resonance imaging has increased in the neonatal period. Improved care of extreme preterm infants has increased their survival, but at the same time there is great concern about the neurological prognosis of large premature infants and seriously ill newborns.
Pointing out that the advances in imaging methods have increased the need for anesthesia outside the operating room in recent years, experts state that infants and children should be treated precisely when taking MRI.
Anesthetized MRI is performed in infants and children, especially since it is not possible for babies to remain completely still while taking MRI.
The need to obtain good quality images has forced the use of sedation and anesthesia in these patients to avoid artifacts due to their movement. This involves exposing newborns to the possible risks associated with sedative anesthetic medication.
In addition, it implies the need for a scheduled admission to control possible side effects, which leads to an increase in the health cost, and is a nuisance for the newborn and his family.
In recent years there are some studies carried out in large neonatal units that show the possibility of performing an MRI without sedation, using a series of measures focused on neurodevelopment. These studies conclude that these procedures are safe for both full-term and preterm infants.
An MRI scan is a test that uses powerful magnets and radio waves to make detailed images of the body. Your child will lie on an MRI scanner while the images are taken.
Children in the first year of life are tested if:
- Birth trauma;
- Infectious and inflammatory diseases;
- Abnormalities with ultrasound screening of the brain, heart, or hip joints;
- Suspected tumor;
- Foreign objects in the digestive tract or airways.
For older children, MRI is prescribed in the presence of the following complaints:
- Frequent headaches and dizziness;
- General weakness, fainting;
- Decreased vision or hearing;
- Poor posture, curvature of the spine;
- Pain syndrome (suspected injury).
Contraindications for the examination
Despite the safety of the technique, MRI has limitations. Absolute contraindications include:
- The presence in the patient’s body of implants or pins containing ferromagnetic alloys;
- Established pacemaker, defibrillator, insulin pump;
- The presence of hearing aids and other complex devices that may fail under the influence of a magnetic field created by the tomograph.
All kinds of food intake are stopped 3 to 6 hours before the examination according to the age of the patient. The patient can drink water up to 3 hours ago. After the procedure is completed, the Anesthesiologist monitors the patient until he wakes up completely, and is then allowed to leave the MRI scan center in Noida.
Performing MRI for children from 5-6 years old without anesthesia is really possible. This requires the presence of mom or dad during the examination procedure, if with the help of persuasion, holding the head and torso you can provide immobility to your child.
