Computed Tomography Of The Chest

Modern diagnostic methods play a key role in medicine. One of the fastest and most reliable ways to diagnose lungs, as well as studies with a segmental dimming syndrome, is a chest CT. This is one of the x-ray diagnostic methods that allow you to achieve a highly accurate, reliable picture of the condition of internal organs and bone tissue.


The benefits of chest tomography

CT of the lungs is one of the most advanced diagnostic methods to make an accurate diagnosis regarding tuberculosis. An increase in the incidence of this contagious disease has shown that the usual x-ray quite often gives inaccurate, hypothetical results.

The tomography will help not only in diagnosis, but also as an evaluation tool to determine the effectiveness of therapy. The specialist will be able to compare the ongoing antibacterial therapy with the dynamics of the course of the disease and give a forecast of the expected outcome. CT will clearly show changes at the parenchyma level.

Thus, the method used compares favourably with both X-ray and magnetic resonance imaging due to the affordable cost, accuracy and other factors described above. When conducting computed tomography, an object is scanned from all sides by a beam of x-rays. The tomography sensors record the speed of the beam. The information received is transmitted to a computer, where it is processed by special programs, and subsequently, three-dimensional images of the scanned area are displayed on the screen.

In such images, pathological formations are well visualized. The main advantage of computed tomography is that it allows you to detect various diseases even in the early stages, which subsequently significantly affects the entire treatment process.

What feelings does the patient experience during the procedure?

Without the use of the contrast medium, the chest CT scan is a painless procedure, which takes place fairly linearly (i.e. it does not induce particular sensations).

With the contrast medium, however, it could cause discomfort, when inserting the needle for the injection of the contrast medium, and a strange metallic taste in the mouth, starting from a couple of minutes after the injection of the above contrast medium.

In some cases, computed tomography of the chest is performed with preliminary contrast. In CT with contrast, an iodine-containing contrast agent is administered intravenously to the patient immediately before the start of the scan. Such a technique makes it possible to more thoroughly evaluate the work of the investigated organ, the condition of its vessels and tissues. However, CT with contrast cannot be used in some groups of patients, as they have diseases in which the use of a contrast medium is contraindicated. Such diseases include:

  • Epilepsy
  • Thyrotoxicosis
  • Cardiopulmonary failure
  • Renal failure
  • Iodine allergy

Today, computed tomography of the chest is one of the most accurate and affordable diagnostic methods. Due to the short research time and minimal x-ray load, computed tomography is increasingly used to diagnose various diseases.

Chest CT Scan: The Best Way To Detect Lung Cancer

Lung cancer treatment is a process planned according to the patient's condition, type and stage of cancer. The treatment plan also takes into account factors such as the patient's general health and age.

If lung cancer is diagnosed at an early stage, surgical treatment is applied first and the recovery rate is very high. However, if the patient is not eligible for surgery, radiotherapy and / or chemotherapy may be recommended to destroy cancerous cells. Promising results can be obtained from targeted drug therapies in advanced stages of the disease. Deciding which treatment method to use will be increased by a group of specialists.

Lung cancer ranks first among cancer deaths worldwide. Despite the most advanced treatment methods, 86% of the patients die within five years. In the early stage, the probability of five-year survival is around 70%. For this reason, the world of science is making serious efforts to catch lung cancer in the very early stages period when it does not cause any complaint and the person does not need to consult a doctor.


Tests that examine the lungs are used to detect (find), diagnose and stage non-small cell lung cancer. Tests and procedures to detect, diagnose and stage non-small cell lung cancer are often performed simultaneously. Some of the following tests and procedures can be used:

  • Physical examination and history: A body exam to check the common signs of health including control sings such as lumps, nodes or anything unusual. The doctor will also check the patient’s habits like smoking, work stress, illness and previous treatments or medicine if taken.
  • Laboratory tests- medical procedures that help test blood, urine, tissue or other substances from the body. These tests help in the diagnosis of diseases and further planning and controlling the treatment to monitor the disease over time.
  • Chest X-ray: An x-ray of the organs or bones located inside the chest. These energy beams help creating an image of the areas inside the body.
  • Chest CT scan cost in Delhi: A procedure that helps creating a series of detailed images of different areas within the body such as abdomen, chest. It is taken from different angles.

Who should have a CT scan?

Any patient over 40 years of age and who has smoked significantly (10 cigarettes or more, for 40 years, 20 or more cigarettes a day for 20 years or 40 or more cigarettes a day for 10 years) or smoked less, but with factors of risk of lung cancer: family history of lung cancer, residence for more than one year in the polluted region, occupational or environmental exposure to asbestos or arsenic or personal history of fibrosis and pulmonary emphysema.


Screening for lung cancer is a complex subject. Despite the encouraging results of the NLST study, many uncertainties remain. For this reason, lung cancer screening should not be promoted publicly outside of study protocols. Patients seeking individual screening should be informed in detail of the benefits and risks of screening, and sent at their own expense to multidisciplinary teams experienced in the diagnosis and treatment of lung cancer, who have established standardized procedures to ensure adequate screening. Coordinated and optimal care throughout the screening process.

Despite recommendations published by some expert groups, chest CT scans are still partially experimental and are not currently validated at the population level. It is important to know chest CT scan cost in Delhi before having one.

Various Tests to Detect Lung Cancer

X-ray exam is used to determine if there are lung nodules. Then you have to determine if they are malignant.

The computed tomography of the thorax (CT scan chest cost in Delhi) is a method of imaging by X-rays, which is commonly used for the diagnosis of lung diseases and is the only proven to reduce the number of deaths per test lung cancer, associated with early detection of the disease. The chest CT is indicated in all patients in which a pulmonary pathology is being studied. In recent years, it has also been shown to be effective as a screening method in lung cancer, similar to mammography for breast cancer screening.

It is not an annoying examination and practically does not have risks, except those related to the minimum radiation exposure. The CT, basically takes many pictures of the inside of the body using x-rays, allows to examine in a few minutes the entire thoracic cavity, so, including the necessary preparation, takes between 15 and 30 minutes.

According to the specialist, it is recommended as a lung cancer screening to perform a normal initial chest CT scan and subsequently a low-contrast, no-dose chest CT scan in the follow-up studies.

Tests and studies to detect lung cancer

If your doctor thinks you might have lung cancer based on the results of a screening test or because of the symptoms you have, other tests and tests will be done to confirm the suspicion.

Medical history and physical examination

Your doctor will ask about your medical history to learn more about any symptoms you have and possible risk factors. You will also be tested for signs of lung cancer or other health problems.

If the results of the history and physical examination suggest that you may have lung cancer, more tests will be done.

Tests to detect lung cancer

Sputum cytology

For this test, a sample of mucus that coughs from the lungs (sputum) is examined under a microscope to determine if it contains cancer cells. The best way to do sputum cytology is to obtain the samples early in the morning for three consecutive days.

Chest x-ray

If you have symptoms that can cause lung cancer, the chest x-ray will often be the first study that the doctor will order. Simple chest x-rays can be done in imaging centers, hospitals, and even in some doctors' offices. If something looks suspicious, your doctor may order other tests.

Computed tomography

A CT (CT scan chest cost in Delhi) uses X- rays to produce detailed cross- sectional images of the body. Instead of taking a picture, like conventional radiography, CT scans take many pictures while a device rotates around you while you lie on a stretcher. Then, a computer combines these photographs to form cross sectional images of the part of the body being studied.

Lung tumors are more likely to be detected on computed tomography (CT) than on conventional chest radiographs. CT scans can also show the size, shape, and position of any tumor in the lung, and can help find enlarged lymph nodes that may contain cancer that has spread from the lung.
