CT Head (Computerized Tomography) Test

Computed tomography (CT) of the head utilises specialised x-ray equipment to assess head injuries, severe headaches, dizziness, and other symptoms of aneurysm, bleeding, stroke, and brain tumours. It also assists your doctor in evaluating your face, sinuses, and skull, as well as planning radiation therapy for brain cancer. In an emergency, it can reveal internal injuries and bleeding quickly enough to help save lives.

Inform your doctor if you suspect you are pregnant. Discuss any recent illnesses, medical conditions, medications, and allergies you've had. If your exam requires intravenous contrast, your doctor may advise you to fast for a few hours beforehand. Your doctor may prescribe medications to reduce the risk of an allergic reaction if you have a known allergy to contrast material. Wear loose, comfortable clothing and leave your jewellery at home. For the procedure, you may need to change into a gown.

Head CT scans are commonly used by doctors to detect:

• Patients with head injuries may experience bleeding, brain injury, and skull fractures.
• A ruptured or leaking aneurysm causes bleeding in a patient who has a severe headache.
• a blood clot or bleeding within the brain in a patient experiencing stroke symptoms
• a stroke, particularly with a technique known as CT Perfusion of the Head.
• Tumours of the brain
• enlarged brain cavities (ventricles) in hydrocephalus patients
• Skeletal diseases or malformations

Wear loose-fitting, comfortable clothing to your exam. For the procedure, you may need to change into a gown.

Metal objects, such as jewellery, eyeglasses, dentures, and hairpins, can interfere with CT images. Leave them at home or take them off before your exam. Some CT scans will necessitate the removal of hearing aids and removable dental work. Women will be required to remove bras with metal underwire. If possible, you should remove any piercings.

If your exam will use contrast material, your doctor may instruct you not to eat or drink anything for a few hours before the exam. Inform your doctor about all medications you are taking, as well as any allergies you may have. If you have a known allergy to contrast material, your doctor may prescribe medications (usually a steroid) to reduce your chances of having an allergic reaction. Contact your doctor well in advance of your exam date to avoid unnecessary delays.

Inform your doctor of any recent illnesses or other medical conditions, as well as any family history of heart disease, asthma, diabetes, kidney disease, or thyroid problems. Any of these conditions may increase the likelihood of a negative effect.

The radiologist should also know if you have asthma, multiple myeloma, or any heart, kidney, or thyroid gland disorder, or if you have diabetes—especially if you are taking Metformin.

CT scans are generally painless, quick, and simple. The amount of time the patient must lie still is reduced with multidetector CT.

 

The technologist will remove your intravenous line following a CT scan. They will use a small dressing to cover the tiny hole made by the needle. You can resume your normal activities right away. 

A CT Head (Computerized Tomography) Test is typically performed in a hospital's radiology department or an outpatient imaging facility. So, for the best services and reliable results, schedule your test at Ganesh Diagnostic in Yamuna Vihar.
