Interpretation of Chest X-rays in Tuberculosis | Lets Talk TB

35 hours ago  · However, TB may mimic other diseases on x-rays, and non TB conditions may look like TB. Thus, chest x-rays are neither specific nor sensitive, and so remain a supplement to microbiological tests such as microscopy, PCR and culture. Treatment of TB purely on the basis of x-rays can result in significant over-treatment with adverse consequences for patients. … >> Go To The Portal

Chest X-Rays are a simple procedure to confirm the presence of TB in the patient. During the procedure, the clinician will take X-rays of the chest from multiple angles. A clinician will analyze the results to determine if the lung X-rays show any signs of advance pulmonary tuberculosis.

Full Answer

What do chest X-rays show with TB?

Chest x-rays are a common test that you may be asked to have when you visit your Tuberculosis (TB) Service. Chest x-rays are used to look for evidence of TB disease in your lungs.

Should we mandate chest X-rays for tuberculosis detection?

Mandated chest x-ray examinations, as a condition of initial or continued employment, have not been shown to be of sufficient productivity to justify their continued use for tuberculosis detection (5).

What is the history of X-ray screening for tuberculosis (TB)?

Until 1972, the use of diagnostic x-ray screening was the unquestioned detection tool for the diagnosis of tuberculosis. Prior to that time, it was felt that properly conducted x-ray screening, including follow-up of the positive finding, would lead to prompt diagnosis and treatment.

What is the role of imaging in the evaluation of TB?

Because of these limitations, imaging plays an important role in evaluation of chest TB (CTB) patients and CT is more sensitive than CXR in this regard.[3,4] For optimal management, the radiologists are often expected to deliver important information, while limiting the radiation exposure and costs to the patients.


Should I schedule a TB Chest X-Ray?

Clinicians frequently recommend tuberculosis X-rays to confirm the presence of TB or damage to the lungs. These X-rays should only be scheduled if:

What will a TB Chest X-Ray show me?

Chest X-Rays are a simple procedure to confirm the presence of TB in the patient. During the procedure, the clinician will take X-rays of the chest from multiple angles. A clinician will analyze the results to determine if the lung X-rays show any signs of advance pulmonary tuberculosis.

Where can I schedule a TB Chest X-ray?

Patients can schedule a TB Chest X-Ray at our Manhattan or Hempstead locations or at many of our nationwide network offices. To find a location that’s most convenient check our location finder page.

Which lobe is most affected by post-primary TB?

Post-primary TB (secondary TB or reactivation TB) is more common in immunocompromised individuals – for example those with HIV/AIDS, those on immunosuppressing drugs, or those with malnutrition or diabetes. The upper lobes are more commonly affected.

Is chest X-ray normal for TB?

Note: The chest X-ray may be normal in primary TB, in fact most patients infected are never unwell enough to require a chest X-ray.

Is TB a radiological disease?

There are no radiological features which are in themselves diagnostic of primary mycobacterium tuberculosis infection (T B) but a chest X-ray may provide some clues to the diagnosis. This image shows consolidation of the upper zone with ipsilateral hilar enlargement due to lymphadenopathy. These are typical features of primary TB.

What is a chest X-ray classification worksheet?

The chest X-ray and classification worksheet by the Centers for Disease Control and Prevention (CDC) of the United States is designed to group findings into categories based on their likelihood of being related to TB or non-TB conditions needing medical follow-up.

Why is B3 TB omitted from the classification scheme?

This was considered a Class B3 TB in the past; however, Class B3 has been omitted from the classification scheme because it has not been found to be associated with active TB. Minor musculoskeletal findings - Minor findings needing no follow-up. Minor cardiac findings - Minor findings needing no follow-up.

What does blunting of costophrenic angle mean?

Blunting of costophrenic angle (in adults)—Loss of sharpness of one or both costophrenic angles. Blunting can be related to a small amount of fluid in the pleural space or to pleural thickening and, by itself, is a non-specific finding (except in children, when even minor blunting may suggest active TB).

What is the color of the arrows on a chest x-ray?

Chest X-ray of a person with advanced tuberculosis: Infection in both lungs is marked by white arrow-heads, and the formation of a cavity is marked by black arrows. 3. Nodule with poorly defined margins - Round density within the lung parenchyma, also called a tuberculoma.

Is CT of the thorax feasible?

X-ray of the thorax in tuberculosis is generally the initial choice of investigation. CT of the thorax is feasible if: There is also suspicion of extrapulmonary tuberculosis, such as gastrointestinal or urogenital tuberculosis. Clinical suspicion remains after a normal X-ray.


More than one hundred years after the discovery of the tubercle bacillus by Robert Koch, tuberculosis is still a major disease in the world. But in the United States, cases and case rates have declined. New cases continue to be found, but most often in urban areas, with increasing numbers prevalent among recent immigrants.


A chest x-ray examination should always be obtained whenever a specific medical indication exists (e.g., relevant history, symptoms and/or significant tuberculin skin test reaction). However, there are several situations where x-ray examinations have traditionally been performed solely because of administrative mandate, protocol, or by routine.

How far away do you stand for chest X-rays?

For a chest X-ray, you will be asked to stand in front of a special panel. The technician aims the X-ray tube at you from about 6 feet away. You may be asked to stand in different positions to ensure a good view of your lungs.

How long do you hold your breath during a CT scan?

The technologist will give you instructions during the test, asking you to raise your arms sometimes and to hold your breath for 10 to 12 seconds.

What are the structures of the thoracic cavity?

The thoracic structures include your lungs and heart and the bones around these areas. Before the study, you will need to remove all clothing and jewelry from the waist up. You will be given a hospital gown to wear. Avoid having any barium studies done two to three days before the CT scan.

What is a CT scan of the chest?

A computed tomography (CT or CAT) scan takes many X-ray pictures to build detailed images of the chest. The pictures are more detailed than a typical X-ray. During a CT scan of the chest, pictures are taken of cross sections or slices of the thoracic structures in your body.

Does X-ray radiation increase the risk of cancer?

The radiation from an X-ray does slightly increase the risk of cancer, but this tiny increase in risk is outweighed by the benefits of looking at the lungs. Be sure to inform your physician and the technician if there is any chance you are pregnant.

How many cases of TB were there in 2012?

TB is a global health problem and the second leading infectious cause of death, after human immunodeficiency virus (HIV). As per the World Health Organization (WHO) reports, 6.1 million cases of TB were notified by national TB programs in 2012, of which 5.4 million were new cases.[5] .

What is the parenchymal zone of TB?

Parenchymal disease in primary TB commonly affects the middle and lower lung zones on CXR, corresponding to the middle lobe, basal segments of lower lobes, and anterior segments of upper lobes. Generally, the primary disease is self-limiting and immune-competent persons remain asymptomatic.

How big are foci in EPTB?

Initially, the foci are about 1 mm in diameter . Untreated, they may reach 3-5 mm in size and may become confluent, presenting a “snow-storm” appearance. Pleural involvement . Involvement of the pleura is one of the most common forms of EPTB and is more common in the primary disease.

Is CTB a disease?

Chest tuberculosis (CTB) is a widespread problem, especially in our country where it is one of the leading causes of mortality. The article reviews the imaging findings in CTB on various modalities.

Does CXR show TB?

Chest radiograph (CXR) finds its place in sputum-negative patients not responding to a course of antibiotics. Though computed tomography (CT) is frequently employed in the diagnosis and follow-up of TB, it does not find a place in the national and international guidelines.

Is there consensus on ultrasound for TB?

Literature is lacking and no consensus exists on use of ultrasound (USG), CT, and magnetic resonance imaging (MRI) in such patients. With India having a large burden of TB, it is important to have established imaging criteria and recommendations.

Can a tuberculous cavity rupture into pleural space?

Tuberculous cavities can rupture into pleural space, resulting in empyema and even bronchopleural fistula. Erosion into the pulmonary artery branches can lead to massive hemoptysis (Rasmussen pseudoaneurysm). Erosion into systemic vessels or pulmonary veins can lead to hematogenous dissemination and miliary TB.
