Background: Chest x-ray is commonly used for pulmonary abnormality screening. However, since the image characteristics of x-rays highly depend on the machine specifications, an artificial intelligence (AI) model developed for specific equipment usually fails when clinically applied to various machines. To overcome this problem, we propose an image manipulation pipeline.

Article Synopsis
  • Lung cancer incidence and mortality rates are notably higher in Asia, particularly East Asia, necessitating improved early detection and treatment strategies compared to Western countries.
  • A virtual meeting of 19 healthcare advisors from 11 Asian countries led to the recommendation of annual low-dose computed tomography screening for those at high risk, along with tailored reassessment intervals based on individual risk factors.
  • Challenges such as economic constraints and insufficient government programs hinder the implementation of effective lung cancer screening in Asia, prompting the need for strategic solutions.

Pulmonary arteriovenous malformation, also known as an arteriovenous fistula, is typically a congenital disease caused by structural deficiencies, particularly the lack of capillary wall development, leading to the abnormal dilation of the pulmonary capillaries. The majority of pulmonary arteriovenous malformation cases are associated with Rendu-Osler-Weber syndrome, also known as hereditary hemorrhagic telangiectasia. Pulmonary arteriovenous malformation rarely occurs due to chest trauma.

Tuberculosis bacilli can enter the human body through the respiratory system, digestive system, or skin and mucous membranes, with the respiratory tract representing the primary point of entry. Once inside the body, tuberculosis bacilli can enter the bloodstream and attack other organs, including the lymphatic system. One manifestation associated with lymphatic tuberculosis infiltration is the presence of large hilar and mediastinal lymph nodes, which are common in children and classified as primary tuberculosis.

Tuberculosis bacilli can enter the human body through the digestive system, the skin, and the mucous membranes, although they mainly enter through the respiratory tract. TB bacilli can enter the bloodstream and attack other organs including the lymphatic system. The TB bacillus can cause miliary tuberculosis once they have entered the bloodstream and infiltrated the lymphatic system, which can then manifest as large lymph nodes in the hilum, mediastinum, and lung.

Lymphangioleiomyomatosis is a rare multisystem disease associated with genetic mutations. The disease usually occurs in women of childbearing age and is characterized by infiltration of immature smooth muscle cells into the lungs, airways, and axial lymphatic systems of the chest and abdomen. The disease often destroys lung parenchyma and produces air cysts.

More than 40 different species of the parasitic flatworm have been identified worldwide, including in Vietnam, but only 10 species are known to cause disease in humans, particularly are transmitted through the ingestion of raw foods, especially freshwater shrimp, and crab. Paragonimiasis causes pneumonia, which can present as acute or chronic, with symptoms including prolonged cough, chest pain, shortness of breath, and hemoptysis. Hematologic changes include eosinophilia and the presence of specific antibodies for in the blood.

Langerhans cell histiocytosis (LCH) refers to a group of diseases of unknown etiology, typically discovered in childhood, characterized by the accumulation of Langerhans cells (white blood cells with large cell nuclei that may contain cytoplasmic histiocytosis X bodies) involving one or more organ systems, including bones, lungs, pituitary gland, skin, lymph nodes, and liver. This disease is also known as histiocytosis X or eosinophilic granuloma. Pulmonary LCH is common (identified in 40% of LCH patients) and may be isolated to the lung or involve other organs.

Sequestration is a congenital abnormality that can occur in both children and adults. The clinical presentation often manifests as recurrent pneumonia throughout the lifetime of the patient. Pathologically, sequestration is a disorganized region of lung parenchyma without a normal pulmonary artery and with no interconnecting air passage (ie, it is isolated from the bronchi and pulmonary arteries).

The unilateral absence of the pulmonary vein, known as pulmonary vein atresia, is a rare type of unilateral pulmonary venous hypoplasia caused by the congenital atrophy of the long pulmonary vein segments in one lung. The involved lung may be normal in size or present with hypoplasia and is often characterized by increased interstitial attenuation and interlobular septal thickening due to venous stasis, edema, and fibrosis. Pulmonary angiography often reveals a reduced size for the lateral pulmonary artery, peripherally sparse pulmonary vessels, contrast stasis, and the inability to visualize pulmonary veins.

Article Synopsis
  • The COVID-19 pandemic has led to a higher demand for testing methods, with RT-PCR being the most definitive but slower option for diagnosis.
  • This study explores using a deep learning-based decision-tree classifier to analyze chest X-ray images for COVID-19 detection and related pneumonia.
  • The classifier features three decision trees, achieving high accuracy rates (98% for normal vs. abnormal images, 80% for tuberculosis detection, and 95% for COVID-19), potentially speeding up patient triage before RT-PCR results come in.
