Computed tomography of the lungs is a method of X-ray examination, which is based on the reproduction of images obtained by circular scanning of the object by a directed beam of X-rays. In the study of lungs, CT provides an opportunity to determine the location of interlobar gaps, intersegmental septa clearly, and assess the state of bronchi and pulmonary vessels. Computerized tomography of the lungs is the fastest and most accurate method of diagnosing diseases in this area.
The Primary Indications for the CT Scan Cost in Delhi NCR Are:
- Tumor Education
- Metastasis of tumors
- Parasitic cysts of the lungs
- Lung disorders caused by rheumatoid diseases
- Suspicion of pulmonary arterial thromboembolism
Computer tomography of the lung can be performed on a conventional tomography or spiral. Traditional CT of the lung is performed to visualize pathological processes in the lungs. The study time is approximately 20 minutes. During the scan, the patient must repeatedly hold his breath. CT of the lungs, carried out on a spiral tomograph lasts only about 15 seconds and it is necessary to delay breathing only once. This method makes it possible to evaluate the state of the lymph nodes of the mediastinal organs as well.
No preliminary preparation is necessary before carrying out a computed tomography of the lungs to the patient. The only exception is when the CT scan cost in Delhi is performed with contrast. In this case, it is recommended to refrain from eating for 5-6 hours before the study, as when injecting a contrast agent, a feeling of nausea may appear.
Contrast substance helps to visualize soft tissues and blood vessels better. During the study, the patient is on the movable table of the apparatus, which moves inside the tunnel, and at this time a tomography ring rotates around it. After the end of the procedure, the patient expects results.
The doctor concludes within 10-15 minutes, then all the data (pictures and their description) are given to the patient's hands or sent by e-mail to the treating doctor. Depending on the type of pathology detected, the treatment can be prescribed by doctors: an oncologist, a surgeon, or a pulmonologist.
HOW TO SCAN?
The specialist helps the patient to take the correct position on the computer tomography table. It is possible to use soft straps or ribbons to help keep the neck in the right place.
During the scan, the patient will be inside the computer tomograph. Many X-rays will pass through the patient's body when the X-ray tube rotates around it. The machine will take pictures from many sides, forming transverse images (slices) of the neck.
The technologist leaves the room. During the scan, the patient will be alone in the place, but the technologist can always see, hear and talk with him through the intercom.
For the first few checks, the table quickly moves through the scanner. The schedule will proceed slower for the rest of the scan. Neck scanning can take up to 15 minutes. Then the doctor looks at the pictures on the computer.
Some patients need a contrast study. Patients will receive a contrast (X-ray dye) during the scan. The difference makes the tissues and blood vessels more visible to the doctor's view to see them in CT images.
