Computed tomography (CT) of the head uses special x-ray equipment to help assess head injuries, severe headaches, dizziness, and other symptoms of aneurysm, bleeding, stroke, and brain tumors. It also helps your doctor to evaluate your face, sinuses, and skull or to plan radiation therapy for brain cancer. In emergency cases, it can reveal internal injuries and bleeding quickly enough to help save lives.

Facial CT differs from noncontrast head CT in several ways. Thinner CT sections are routinely performed to increase sensitivity for fracture. In facial CT, both axial and coronal views are routinely provided for interpretation; in noncontrast head CT, axial images are the routine series. Facial CT for trauma is performed without intravenous (IV) contrast, as findings of trauma such as bony fracture, blood in sinus spaces (forming air–fluid levels), and soft-tissue swelling do not require IV contrast for identification. When CT is used for evaluation of nontraumatic facial complaints, IV contrast should be administered if possible. Neoplasms, vascular malformations, and infectious and inflammatory conditions all may show enhancement with IV contrast, aiding diagnosis. As a consequence, if brain injury or nonfacial skull fracture is suspected, noncontrast head CT should be obtained.

CT PNS helps to diagnose sinusitis. This evaluates sinuses that are filled with fluid or thickened sinus membranes and detect the presence of inflammatory diseases.

Temporal bone CT is a limited kind of head CT that focuses on the lower part of the skull and the surrounding soft tissues, and is often used in patients with hearing loss, chronic ear infections, and middle and inner ear diseases.

CT HEAD PLAIN is used for diagnosis of possible damage after trauma to the head, such as soft tissue injuries, brain bleeding, and bone injuries assessing a person having stroke-like symptoms to see whether there are signs of a blood clot or brain bleeding looking for a possible brain tumor or other brain abnormality,checking the effectiveness of medical treatments in shrinking a brain tumor, assessing birth conditions that cause the skull to form abnormally and evaluating a person with a history of hydrocephalus, a condition in which an accumulation of cerebrospinal fluid causes the enlargement of the brain ventricles

CT scanning is painless, noninvasive and accurate. It's also the most reliable imaging technique for determining if the sinuses are obstructed and the best imaging modality for sinusitis.

A CT (computed tomography) scan uses X-rays to make detailed pictures of your body and structures inside your body. A CT scan of the neck can give your doctor information about your neck, throat, and tonsils and other structures in the neck area.

High-resolution computed tomography (HRCT) is a method of examination which is more precise than chest 2-rat in the diagnosis and monitoring of diseases

amount of radiation is higher than the amount used with an X-ray. As a result, an abdominal CT scan slightly increases your risk of cancer.

An abdominal and pelvic CT scan can diagnose obstructions, kidney stones, hernias, masses, tumors, infections, aneurysms and many other problems

Image result for KUB PLAIN Computed tomography of kidneys, ureters and bladder (CT KUB) is a quick non-invasive technique for diagnosis of urolithiasis. It is usually considered the initial imaging modality for suspected urolithiasis in an emergency set

The CT scanner looks like a large circle with a hole in the middle, called a gantry. During the scan, you'll lay flat on a table,

3D CT is used to visualize the fracture of bone.
