CT Scan - Brain


What is a CT scan of the brain?

(Head CT Scan, Intracranial CT Scan)

 CT scans can offer more precise information on the brain's tissue and brain structures than conventional X-rays of the head. This results in offering more details about brain injuries and diseases. Brain.

When undergoing a CT, the beam of X-rays is positioned in a circle around the body, allowing numerous perspectives of the brain.

Brain CT scans can be conducted using or with no "contrast." Contrast is a term used to describe a substance taken orally or injected in one's intricate (IV) line, which results in the specific organ or tissue in question being observed more clearly. Contrast exams might require you to fast for a specified duration before the procedure, and your doctor will inform the patient ahead of time before your procedure.

Other procedures that can be used to determine the presence of brain disorders are imaging with Xrays, magnetic resonance imaging (MRI) of the brain, positron emission tomography (PET) scan of the brain and brain arteriograms.

What's the function that the brain plays?

It is a component of our Central Nervous System (CNS). The brain is a vital organ responsible for thinking, emotion, memory, and the motor abilities of our eyes, breathing, temperature, hunger, and all other processes that regulate the body.

What are the various components in the brain?

The brain may be split into cerebrum cerebellum, brainstem, and brainstem.

  • Cerebrum. The cerebrum (supratentorial or frontal part of the brain) is comprised of left and right hemispheres. Its main functions are movements, initiation and coordination of movement temperature and touch, vision hearing and judgment, reasoning, emotional reactions, problem-solving and learning.

  • Brainstem. It is the brainstem (midline or middle of the brain) that comprises the midbrain, the pons, and the medulla. Its functions include the movements of the eyes and mouth, transmitting sensory signals (hot and painful and so on. ) hungry and respirations, conscious heart function and body temperature, involuntary muscular movements, coughing, sneezing or vomiting, as well as swallowing.

  • Cerebellum. The cerebellum (infratentorial or the back of the brain) is located in the back of the head. Its purpose is to regulate voluntary muscle movements and to ensure balance, posture and balance.

In particular, other areas of the brain comprise the following:

  • Pons. A part of the brain that is located in the brainstem. The pons houses several controlling areas that control facial movements and the eye and facial sensation and hearing and balance.

  • Medulla. The tiniest section of the brainstem. The medulla is the most vital component of the brain and is home to important control centres for the heart and the lung.

  • The spinal cord. A huge cord of nerve fibres in the back. It extends from the brain's top-down to the lower back. The spinal cord transmits messages between the brain as well as the other parts of the human body.

  • Frontal lobe. The largest area of the brain, located at the top of your head. The frontal lobe has a major role in the development of personality traits and movements.

  • Parietal lobe. The middle of your brain. This area assists in identifying objects and comprehending spatial relationships (where the body's position is compared with objects surrounding the body). The parietal brain lobe is involved in the interpretation of pain and touching within the body.

  • Occipital lobe. The occipital region is the part behind the brain which is associated with vision.

  • Temporal lobe. The brain's sides are the temporal lobes involved in speech, memory, and the sense of smell.

What are the main reasons behind the need for CT imaging of the brain?

  • The CT exam of your brain can be done to examine the condition of your brain, for example, tumours, as well as other lesions, injuries or intracranial bleeding, as well as structural abnormalities (e.g., hydrocephalus or infections) and brain function) or other disorders) in particular when another kind of test (e.g. scans, X-rays, or physical examination) aren't conclusive.

  • A brain CT could also be used to determine the impact of treatments on cancerous brain tissue and determine clots within the brain, which could cause strokes. Another reason to use the brain CT is to offer guidelines for surgery for the brain or biopsies.

  • There could be additional reasons why your doctor should suggest the use of a CT for the head.

What are the potential risks associated with the CT imaging of your brain?

  • It is possible to inquire with your doctor about the quantity of radiation used during your brain CT procedure and the risk specific to your situation. It is important to keep a log of any previous radiation exposure, like prior CT scans, and other types of X-rays, in the order that you can notify your physician. The risks related to radiation exposure could be due to the cumulative amount of X-ray tests or treatments over a lengthy time.

  • To protect your health, you should take the following tips before scheduling a CT scan of your brain:

Pregnancy If you're pregnant or suspect you might be pregnant, it is important to inform your physician. If it is required to undergo a CT of your brain, specific precautions must be taken to limit your exposure to radiation for the foetus. Media with contrast: If contrast media is employed in the brain CT the patient could have an anti-inflammatory reaction to the medium. Some patients should not use contrast media containing iodine. People who are allergic or sensitive to medicines should inform their doctor. When scheduling your CT scan for the brain, you should inform your doctor. CT scan, be sure to notify the representative from the access centre whether you've had the reaction of an allergy to contrast medium or if you suffer from kidney failure or any other kidney-related issues.

Diabetic: Patients taking Metformin, a diabetes medicine (Glucophage), must notify their doctor before having the IV injection of contrast because it could trigger a rare condition known as metabolic acidosis. If you are taking Metformin, you'll be asked to discontinue the medication during the procedure. You should wait for at least 48 hours following the procedure before you can resume taking this medication. The results of a blood test are used to determine kidney function might be needed before resuming your use of Metformin.

  • There are other potential risk factors based on your specific medical health condition. Make sure you discuss any concerns you have with your physician before performing the procedure.

How can I prepare for the CT exam of the brain?

  • If you're scheduled for computed tomography (CTA), you will be given specific directions before you schedule your appointment. The following guidelines will assist in preparing you for the brain CT

  • The clothing you may be asked to put on an appropriate gown for patients. If this is the case, a gown will be provided to you. Remove all piercings and keep all jewellery and valuables at home.

    Medication All patients can use their prescribed medication at the regular rate unless ordered.
  • People with diabetes: Diabetics need to have a light breakfast and lunch at least three hours before their scheduled CT scan. If you take an oral medication for the condition, you could be asked to cease your treatment for 48 hours following the Brain CT scan. If you've undergone a CT scan using sarwarpro radiology, detailed instructions will be provided after the exam.
  • Food and drinks If your doctor has ordered the CT scan of the brain CT exam that was not accompanied, by contrast, you may drink, eat and take your prescribed medication before the exam. If your doctor recommended the CT scan of your brain with contrastdo not consume anything for 3 hours before the brain CT. It is recommended to drink clear fluids.
  • Media with contrast: You must sign a consent document that outlines the risks, and potential side-effects of contrast media injected into small tubes placed into the intravenous (IV) vein. The most popular kind that uses a brain CT scan with contrast is the double-contrast which requires the consumption of contrast media before the test begins, along with the contrast IV. If you've experienced mild or mild reactions previously, you'll likely require medications before your CT scan. CT scan.
  • Based on your medical conditions, Your physician may suggest specific steps to assist with your brain CT preparation.

What happens when you take what happens during a CT imaging of your brain?

  • Brain CT scans are conducted on an outpatient basis or during your hospitalization. The procedure may differ based on your medical condition and physician's guidelines.

  • In general, an MRI or CT scan of the brain CT scan is a process that involves these steps.

  • If you have an operation that requires contrast, the IV line will be inserted within the arm or hand to inject the contrast medium. If you have oral contrast, the patient will receive an injection of contrast liquid from taking in.

  • Once the process is completed, after which, you will be removed from the scanner

  • Inform the technologist if you experience any breathing problems such as sweating, numbness, sweating and heart palpitations.
