“…Therefore, RAD-AID and International Day of Radiology [65], an annual event supported by the European Society of Radiology, the American College of Radiology, and the Radiological Society of North America, have started to emphasize the importance of pediatric radiology [7]. Chest radiography is a valuable diagnostic tool in the pediatric population, and it is a key diagnostic tool in TB detection for pediatric patients in low-burden countries, due to the lower sensitivity of TB culture test (current gold standard for active TB detection) in pediatrics [66].…”

“…According to the 2015 RAD-AID Conference on International Radiology for Developing Countries report [ 7 ], approximately 3 to 4 billion people in the world do not have easy access to radiology services; among them, approximately 500 million to 1 billion are children. Therefore, RAD-AID and International Day of Radiology [ 65 ], an annual event supported by the European Society of Radiology, the American College of Radiology, and the Radiological Society of North America, have started to emphasize the importance of pediatric radiology [ 7 ].

“…Chest radiography is widely available, affordable, and has lower radiation dose compared to other imaging tools [ 1 ]. Particularly, under-resourced regions of the world that also have to face a heavy burden of infectious diseases, such as TB, commonly use chest X-ray (CXR) as frontline diagnostic imaging due to lower infrastructure setup, operational costs, and portability [ 7 , 8 ]. Automated analysis of CXR can assist in population screening as well as the radiologist in triaging and interpretation, thereby reducing their workload [ 6 , 9 ].…”

A review on lung boundary detection in chest X-rays

PurposeChest radiography is the most common imaging modality for pulmonary diseases. Due to its wide usage, there is a rich literature addressing automated detection of cardiopulmonary diseases in digital chest X-rays (CXRs). One of the essential steps for automated analysis of CXRs is localizing the relevant region of interest, i.e., isolating lung region from other less relevant parts, for applying decision-making algorithms there. This article provides an overview of the recent literature on lung boundary detection in CXR images.MethodsWe review the leading lung segmentation algorithms proposed in period 2006–2017. First, we present a review of articles for posterior–anterior view CXRs. Then, we mention studies which operate on lateral views. We pay particular attention to works that focus their efforts on deformed lungs and pediatric cases. We also highlight the radiographic measures extracted from lung boundary and their use in automatically detecting cardiopulmonary abnormalities. Finally, we identify challenges in dataset curation and expert delineation process, and we listed publicly available CXR datasets.Results(1) We classified algorithms into four categories: rule-based, pixel classification-based, model-based, hybrid, and deep learning-based algorithms. Based on the reviewed articles, hybrid methods and deep learning-based methods surpass the algorithms in other classes and have segmentation performance as good as inter-observer performance. However, they require long training process and pose high computational complexity. (2) We found that most of the algorithms in the literature are evaluated on posterior–anterior view adult CXRs with a healthy lung anatomy appearance without considering challenges in abnormal CXRs. (3) We also found that there are limited studies for pediatric CXRs. The lung appearance in pediatrics, especially in infant cases, deviates from adult lung appearance due to the pediatric development stages. Moreover, pediatric CXRs are noisier than adult CXRs due to interference by other objects, such as someone holding the child’s arms or the child’s body, and irregular body pose. Therefore, lung boundary detection algorithms developed on adult CXRs may not perform accurately in pediatric cases and need additional constraints suitable for pediatric CXR imaging characteristics. (4) We have also stated that one of the main challenges in medical image analysis is accessing the suitable datasets. We listed benchmark CXR datasets for developing and evaluating the lung boundary algorithms. However, the number of CXR images with reference boundaries is limited due to the cumbersome but necessary process of expert boundary delineation.ConclusionsA reliable computer-aided diagnosis system would need to support a greater variety of lung and background appearance. To our knowledge, algorithms in the literature are evaluated on posterior–anterior view adult CXRs with a healthy lung anatomy appearance, without considering ambiguous lung silhouettes due to pathological deformities, anatomical alte...

“…Furthermore, the absence of a national or regional Canadian GHI group makes it difficult for interested, self-directed residents to find opportunities. RAD-AID International, an American-based international organization focused on improving radiology for poor and lowresource countries, has 46 chapters at Accreditation Council for Graduate Medical Educationeaccredited academic centres [27]. To our knowledge, no Canadian RAD-AID chapters exist.…”

Since the introduction of MRI as a sustainable diagnostic modality, global accessibility to its services has revealed a wide discrepancy between populations—leaving most of the population in LMICs without access to this important imaging modality. Several factors lead to the scarcity of MRI in LMICs; for example, inadequate infrastructure and the absence of a dedicated workforce are key factors in the scarcity observed. RAD‐AID has contributed to the advancement of radiology globally by collaborating with our partners to make radiology more accessible for medically underserved communities. However, progress is slow and further investment is needed to ensure improved global access to MRI.
