    “…INTRODUCTION: Penetrating thoracic injuries are a common presentation in Emergency Departments in South Africa with pneumothorax, haemothorax and haemopneumothorax (PTX/HTX/HPTX) a cause of morbidity and mortality. Serial chest X-rays (CXRs) are used to assess patients with penetrating thoracic injury without PTX/HTX/HPTX on initial CXR in order to increase sensitivity and thus detection of PTX/HTX/HPTX. …”

    “…Four hundred and two thoracic segmentations were first generated automatically by a U‐Net based algorithm trained on chest CTs without cancer, manually corrected by a medical student to include the complete thoracic cavity (normal, pathologic, and atelectatic lung parenchyma, lung hilum, pleural effusion, fibrosis, nodules, tumor, and other anatomic anomalies), and revised by a radiation oncologist or a radiologist. …”

    “…IMPORTANCE: Both noninvasive anatomic and functional testing strategies are now routinely used as initial workup in patients with low-risk stable chest pain (SCP). OBJECTIVE: To determine whether anatomic approaches (ie, coronary computed tomography angiography [CTA] and coronary CTA supplemented with noninvasive fractional flow reserve [FFR(CT)], performed in patients with 30% to 69% stenosis) are cost-effective compared with functional testing for the assessment of low-risk SCP. …”

    “…With sensitivity comparable to reverse transcription polymerase chain reaction (RT-PCR), the absence of ground glass opacities (GGOs) on chest CT scan was useful to rule out COVID-19. We evaluated the specificity of chest CT scan findings for COVID-19 along with other clinical and laboratory findings. …”

    “…Recent research has shown radiography of COVID-19 patient, such as CT and X-ray, contains salient information about the COVID-19 virus and could be used as an alternative diagnosis method. Chest X-ray (CXR) due to its faster imaging time, wide availability, low cost, and portability gains much attention and becomes very promising. …”
