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.

Is CT Scan Imaging Same as MRI?

Both MRI and CT are two of the significant advances in current medicine since they allow the examination and detection of diseases using non-invasive methods, without the use of pesky and aggressive techniques such as lumbar punctures or arthrography for the patients.

For both reviews, the patient should lie on a stretcher and enter a relatively narrow cylindrical tunnel. The difference is that in MRI test the tube is a large electromagnetic magnet that allows you to take pictures of the inside of the body by subjecting it to a magnetic field. In a CT, the images are taken using an X-ray beam that makes a circular movement that surrounds the area to be investigated (multiple X-rays from various angles).

With the CT tests, it is possible to reconstruct in three dimensions the area explored, which is very useful when planning a surgery and is the order of the day to locate and treat tumors. Both are image tests, but they are not the same. The CT Scan cost is highly dependent on the scan center and clinic you are going for!

Magnetic resonance uses powerful magnetic fields to produce and detect changes at the molecular level of substances like the hydrogen that contains our body. These changes are very subtle and disappear when we leave the machine, but the machine can detect them and translate them into images of the interior of the body.

Both CT and resonance allow us to explore the inside of the body, but each one is more sensitive to a particular type of injury, so your doctor will indicate the one that is most appropriate as the case may be.

What is a CT Scan Test? What Does it Consist of?

The CT scan test is performed with a device called a scanner. During this test, the body is subjected to multiple rays released simultaneously from different angles, and then a computer assembles them to generate an image of the area to be studied. CT scanning is more detailed than an x-ray since only a beam of light is used on the current x-ray.

Because CT scan is a non-invasive procedure that provides detailed cross-sectional views of all tissue types, it is becoming the ideal method to diagnose many intestinal diseases such as diverticulitis and appendicitis and to visualize the liver, spleen, pancreas and the kidneys.

And Magnetic Resonance- What Does it Consist of?

On the other hand, Magnetic Resonance is a machine that allows obtaining an image of the soft tissues of a patient using the use of a magnetic field. Powerful magnets and radio waves are used to create body images. The main difference between CT and MRI test is that the second one does not use X-rays. Other differences are that the CT scan is faster to perform but has a lower resolution.

Because MRI test can give such clear images of the soft tissues around the bones, it is the most appropriate examination for spine and joint problems. It is also widely used to diagnose sports injuries, especially in the knee, shoulder, hip, elbow, and wrist. The images allow the doctor to see even tiny tears and lesions in the ligaments and muscles.
