CT scan of the skull

What is it?

Skull CT is a computed tomography (CT or CAT) scan of the skull or cranium (head). It is a diagnostic imaging exam that allows the study of the encephalon.
It is very important in the study of various pathologies (diseases), such as cerebral thrombosis, cerebral aneurysm, benign or malignant tumors (cancer), neurological alterations, among others. In general, the CT (computed tomography) is one of the most reliable and safe examination methods available today.
It is quick, simple and completely painless.
CT scans use a device that emits X-rays, taking highly detailed axial images of your body.
Therefore, with a CT scan, the inside of your body can be portrayed with complete precision and confidence for later analysis by your doctor.

X-radiation in CT scans is minimal due to modern technology and the short duration of the scan.
However, in women of childbearing age, please inform the doctor/technician if you are pregnant or suspect pregnancy.

The NRD has a new Philips 128-slice CT scanner with state-of-the-art technology.
The new 128-slice CT scanner provides examinations with low radiation dose and high image quality for all patients.
With an innovative platform and workflows, the scanner enables excellence in CT imaging studies with consistently high image quality for all patients.

CT scan of the skull with contrast

In this examination, to complement the study and/or on medical advice, it may be necessary to administer a small injection of a contrast product (intravenous contrast), with which you may feel a sensation of warmth that will soon disappear.
Some allergic reactions to contrast have been reported. To avoid this, it is important to inform the doctor/technician of any possible allergies to medication, food or if you suffer from any allergic disease (asthma or allergic rhinitis).

If the test is to be carried out with intravenous contrast, a 4-hour fast is required.

You will receive this information when you book the exam.

Preparing for a CT scan of the skull

If the examination is to be carried out with intravenous contrast, the main preparation is a 4-hour fast.
In the case of pediatric exams, fasting will be between 4 and 6 hours (if performed with anesthetic support).

If the examination is to be carried out with oral contrast, you should come to the Clinic between 1 and 2 hours before the examination appointment to make the appropriate oral preparation.
Oral contrast does not require fasting.

You will receive this information when you book the exam.

You must bring all previous exams.

Orientation during the CT scan of the skull

The CT scan is carried out with the patient lying on a table (bed) which enters a small tunnel (apparatus), open at both ends.
You always have the opportunity to communicate with the Medical/Technical staff via intercom during the examination (5 to 15 minutes, depending on the area of the body being studied); however, it is only advisable to do so in between the examination sequences, in order to avoid any movement artifacts that could hinder the Medical reading.

  • Please remain still during the examination.
  • For examinations of the neck area, please avoid swallowing during the examination.
  • When examining the head and neck, please remove all jewelry, staples, glasses, hearing aids and dentures.
  • For thoracic, abdominal and pelvic examinations, please follow the instructions (e.g. hold or inhale your breath) recommended by your healthcare professional.
