Benefit of CT Scan of the Chest

Computed tomography occupies an essential place in the diagnosis of diseases of the lungs and mediastinal organs. The procedure is based on the use of X-rays with further reproduction of the obtained data in the form of images on a computer screen. In contrast to conventional X-rays, computed tomography shows color images on the screen, which makes it possible to more correctly assess the state of scanned objects and diagnose diseases of the lungs, blood vessels, heart, and esophagus. Computed tomography of the chest is an indispensable method for diagnosing lung cancer, tuberculosis, and pneumonia. This method is also highly informative when diagnosing diseases of the mediastinum organs: lymphomas, aneurysms, thromboembolism, etc.

When conducting computed tomography, an object is scanned from all sides with an X-ray beam. The tomograph sensors record the speed of passage of the beam. The received information goes to a computer, where individual programs process it, and later on, three-dimensional images of the scanned area are displayed on the screen. On such pictures, pathological educations are well visualized. The main advantage of computed tomography is that it allows you to identify various diseases even in the early stages, which further significantly affects the entire process of treatment.

The main indications for chest CT scan are:

•       Infectious diseases

•       Inflammatory diseases

•       Pulmonary embolism

•       Tumor diseases

•       Pathologies of large blood vessels of mediastinal organs

•       Lymph node lesions

In some cases, computed tomography of the chest is performed with prior contrasting. With CT with contrast, immediately before the start of the scan, an iodine-containing contrast agent is injected intravenously. This method of carrying out makes it possible to more thoroughly evaluate the work of the studied organ, the state of its vessels and tissues. However, CT with contrast cannot be used in some groups of patients, since they have diseases in which the use of a contrast agent is contraindicated.

Benefits of Chest Tomography

High image clarity, since the resolution of most modern devices, is at least 1-1.5 millimeters. This greatly facilitates the work of the diagnostician, allows you to interpret the data accurately.

The ability to obtain images in three-dimensional mode, thanks to the function of volumetric imaging computed tomography. The appearance of artifacts caused by the involuntary movements of patients is minimized.

Viewing images of chest slices in retrospective mode at any time after the study, subject to preservation of data on a hard disk or CD. The reconstruction step can vary widely.

The undoubted advantages that can be assessed not only by diagnosticians but also by patients who have undergone a study with a tomograph include

•       Efficiency diagnostics, which takes no more than 15-20 minutes.

•       The painless method that does not even cause discomfort.

•       The accuracy of the diagnosis, based on the data obtained.

•       The relatively low price of chest CT, especially in comparison with MRI.

Today, Computed Tomography of the chest is one of the most accurate and accessible diagnostic methods. Due to the short study time and minimal X-ray load, computed tomography is increasingly used to diagnose various diseases.
