During a CT scan, the patient lies on a bed that slowly moves through the gantry while the x-ray tube rotates around the patient, shooting narrow beams of x-rays through the body.
Instead of film, CT scanners use special digital x-ray detectors, which are located directly opposite the x-ray source..

It uses X-ray and computer technology to make detailed pictures of the organs and structures inside your chest.
These images are more detailed than regular X-rays.
They can give more information about injuries or diseases of the chest organs..
What is computed tomography CT in lungs?
Computed tomography (CT) of the chest uses special x-ray equipment to examine abnormalities found with other imaging tests and to help diagnose the cause of unexplained cough, shortness of breath, chest pain, fever, and other chest symptoms.

- A CT scan of your thoracic spine allows the radiologist to look at different levels or slices of the middle back using a rotating X-ray beam.
The radiologist is able to view each slice to assess for injuries, including ruptured disks and other bony abnormalities. - CECT (Contrast Enhanced Computerized Tomography) chest scan is used to create a detailed three-dimensional image of the chest or thorax to identify problems associated with the heart, lungs, food pipe, rib cage, spinal column, and surrounding soft tissues.
- Chest imaging includes use of plain x-rays, computed tomography (CT) scanning, magnetic resonance imaging (MRI), nuclear scanning, including positron emission tomography (PET) scanning, and ultrasonography.
- For a ventilation scan, you will breathe in a gas with the tracer in it through a face mask or a tracer may be injected.
You will then be asked to hold your breath for a short time.
The radiologist will use the scanner to take images of your lungs while you are holding your breath. - Normal CT scans of the lungs create three to five millimetre slices of the lung tissue for evaluation.
These slices are great for looking at the lung tissue for nodules or masses but not for appreciating the fine details.
HRCT scans take one millimetre slices.
The thinner slices allow for a much more detailed analysis.
