How to make a brain CT scan children?


Computed tomography — a new diagnostic method in relation to the other, allowing to obtain reliable information on pathological changes in the human body. CT of the brain the doctor will receive images of the scanned layers of the body. This method of diagnosis for certain diseases is considered the most informative and less safe compared to MRI.

What is a CT scan differs from an MRI

CT and MRI are quite different diagnostics. They differ in the principle of the scanning of internal organs.

The doctor can be different reasons to a child to send for a CT scan.

Mostly assigned to:

  • when benign or malignant neoplasms (cysts, astrocytoma, ependymoma, and so on)
  • if symptoms of intracranial pressure (headaches, frequent nausea, Central paralysis, sleep disorders, attention, memory),
  • in the presence of deformation of the skull bones as the result of abnormalities of fetal development (carniolans, Cephalonia, and others),
  • when signs of inflammation of the brain as a result of disease (abscess of the brain, meningitis, encephalitis, and so on)
  • when receiving intracranial injury,
  • if you suspect hydrocephalus of the brain
  • if you identify signs of mental disorders.


Computed tomography of the brain administered to children when it is impossible to put a definite diagnosis and while receiving serious head injuries. If your doctor has prescribed to undergo this diagnostic method, it’s necessary. This inspection allows to detect abnormalities in the early stages of development.

What shows CT scan

This research method allows us to study the relationship between clinical and morphological expression after injury. Also with the help of CT it is possible to predict the anticipated consequences that may occur because of violations of certain functions of the brain. A detailed study and analysis of the structures, extent of injury, as well as the localization of possible pathological changes allows the doctor to prescribe the necessary treatment and subsequent rehabilitation program individually for each child.

What changes can be diagnosed by CT:

  1. The clarity of the boundaries of the ventricles, cortex and the skull bone due to pathological or traumatic injuries.
  2. Possible displacement of the location of the ventricles because of the tumors large size.
  3. Pathological changes in nerve fibers and blood vessels due to injury or disease.
  4. Excessive fluid accumulation, hemorrhages resulting from injury or pathological changes in the tissues of the brain.
  5. The presence of a foreign body after trauma.


Follow all recommendations of the attending physician, this will avoid more serious consequences from his injuries or to detect the disease at an early stage of development. After the conducted procedure of examination of the brain in children by CT, the doctor will be able to deliver error-free diagnosis. Then decide on the appointment of drugs for the treatment and rehabilitation of children.

Computer tomography does not need any special training, only the last meal should be 4 hours before the procedure. When using an x-ray contrast agent must be reported on the presence of diagnosis of diabetes, medication allergies in the medical history of the child.

How is the procedure of CT

Due to the fact that the child can not keep still during the whole procedure, they give him General anesthesia. Therefore, it is weighed before diagnosis to determine the exact required dosage of anesthesia. If it is necessary to study the cerebral vessels (angiography), then the contrast medium injected intravenously for the diagnosis of blood vessels, which contains iodine. Then it is placed on the table in the correct position, if necessary, under a head enclose the stand. Then the head fixed with special belts, the diagnostic table with the patient is pushed into the chamber of the device and scans of the brain.

Contraindications and limitations to the diagnosis

Before you can assign a CT examination, the doctor explores the patient’s history for contraindications to the diagnosis.

Contraindications include:

  • Renal failure in severe form.
  • The presence of surgical staples, clips, implants.
  • Expressed mental deviations.
  • Allergic reactions to drugs and iodine-containing drugs.
