OBJECTIVE: We studied the association of occupational and environmental agents with chronic fibrosing idiopathic interstitial pneumonia (IIP) in South Korea. METHODS: We recruited 92 patients with chronic fibrosing IIP and 92 matched controls who had normal chest radiograph findings by age and gender. We used a structured exposure questionnaire to evaluate potential occupational and environmental risk factors for chronic fibrosing IIP, with adjustments for age, smoking, and clinical risk factors...

Hodgkin lymphoma (HL) commonly presents as nodal disease, but in a subset of cases, the disease primarily develops in extranodal sites. Primary classical HL of the gastrointestinal (GI) tract is an extremely rare occurrence. Primary nature of the disease is confirmed after a complete lymphoma work up including chest radiograph, computed tomography scan, peripheral blood, and bone marrow studies. Only a few cases of primary GI lymphomas with limited immunohistochemical or molecular confirmation have been reported in literature...

In recent years there has been a significant evolution in the field of cardiovascular implantable electronic devices (CIED). Pacemakers can now be leadless, implantable cardioverter defibrillators can be entirely subcutaneous and implantable loop recorders have become miniaturised. Driven by technological advances and an ageing population implant numbers have also steadily increased. These highly prevalent systems are all radio opaque and are frequently observed on chest radiographs, yet the devices are neither well recognised nor understood...

Blunt injuries to the chest wall are an important chapter on emergency room (ER) departments, being the third most common injuries in trauma patients which ominous complications could appear. This article describes different types of traumatic events affecting the chest wall, which maybe misdiagnosed with conventional X-ray. Special emphasis has been done in computed tomography (CT) and multidetector CT (MDCT) imaging. This technique is considered the "gold-standard" for those traumatic patients, due to its fast acquisition covering the whole area of interest in axial plane, reconstructing multiplanar (2D, 3D) volume-rendered images with a superb quality and angiographic CT capabilities for evaluating vascular damage...

Objectives Low-dose computed tomography lung cancer screening has been shown to reduce lung cancer mortality but has a high false-positive rate. The precision medicine approach to low-dose computed tomography screening assesses subjects' benefits versus harms based on their personal lung cancer risk, where harms include false-positive screens and resultant invasive procedures. We assess the relationship between lung cancer risk and the rate of false-positive LDCT screens. Methods The National Lung Screening Trial randomized high-risk subjects to three annual screens with low-dose computed tomography or chest radiographs...

BACKGROUND: Despite increases in imaging guidelines for other body-regions during initial trauma assessment and the demonstrated utility of chest radiographs (CXR), guidelines for use of thoracic computed-tomography (TCT) are lacking. We hypothesized that TCT utilization had not decreased relative to other protocolized CTs, and mechanism and CXR could together predict significant injury independent of TCT. METHODS: We performed a retrospective review of blunt trauma patients ≤18 y...

RATIONALE: Patients with malignant pleural effusion (MPE) experience breathlessness, which is treated by drainage and pleurodesis. Incomplete drainage results in residual dyspnea and pleurodesis failure. Intrapleural fibrinolytics lyse septations within pleural fluid, improving drainage. OBJECTIVES: To assess the effects of intrapleural urokinase on dyspnea and pleurodesis success in patients with non-draining malignant effusion. METHODS: Prospective double blind randomised trial; patients with non-draining effusion were randomly allocated 1:1 to intrapleural urokinase (100,000 IU three doses 12 hourly) or matched placebo...

Pleuritic chest pain is characterized by sudden and intense sharp, stabbing, or burning pain in the chest when inhaling and exhaling. Pulmonary embolism is the most common serious cause, found in 5% to 21% of patients who present to an emergency department with pleuritic chest pain. A validated clinical decision rule for pulmonary embolism should be employed to guide the use of additional tests such as d-dimer assays, ventilation-perfusion scans, or computed tomography angiography. Myocardial infarction, pericarditis, aortic dissection, pneumonia, and pneumothorax are other serious causes that should be ruled out using history and physical examination, electrocardiography, troponin assays, and chest radiography before another diagnosis is made...

OBJECTIVE: To identify risk factors for microbiologically confirmed intrathoracic tuberculosis in children. METHODS: Children, 6 mo to 15 y of age, attending the out-patient department of a tertiary care centre in India, with probable intrathoracic tuberculosis were enrolled. Microbiological confirmation of tuberculosis was defined as positivity on smear (Ziehl-Neelsen staining) and/or Xpert MTB/RIF and/or MGIT-960 culture. Association of various factors with microbiological confirmation were assessed by univariate and multivariate analysis...

A healthy 19-year-old man was referred to our hospital due to an elongated left heart border on chest radiograph. Transthoracic echocardiography showed a posteriorly deviated left ventricular apex, increased right ventricular dimension, and hypokinesis of the interventricular septum. Pulsed Doppler echocardiogram revealed a triphasic mitral inflow pattern. Myocardial longitudinal strain rate imaging revealed that the early diastolic strain rate abruptly decreased to a negative value and then became positive at the left ventricular apex...

OBJECTIVE: To evaluate the effectiveness of bone suppression imaging (BSI) software in lung-nodule detection on chest radiographs (CXRs) in relation to nodule location and observer's experience. MATERIALS AND METHODS: The CXRs of 80 patients, of which 40 had a lung nodule (8 to 30 mm in diameter) and 40 did not have any nodules, were interpreted by 20 observers comprising of 7 pulmonologists with >10 years of experience and 13 pulmonology residents. Each patient's image was sequentially read, first using the standard CXR and thereafter with the BSI software...

Pneumoconiosis is an occupational disease accompanied by long-term lung impairment for which prediction of prognosis is poorly understood because of the complexity of the inhaled particles. Micro-proton-induced X-ray emission (micro-PIXE) analysis, which is advantageous for high-sensitivity 2D element mapping of lung tissues, was used to investigate element-based predictive factors of prognosis in Chinese patients with welder's and coal miner's pneumoconiosis. Chest radiographs and lung function tests showed that most of the coal miners deteriorated, while symptoms in some welders were alleviated after five years, as determined by comparing percent vital capacity (VC%) and forced expiratory volume in the first second over forced vital capacity (FEV1...

We report a rare case of a large mediastinal pancreatic pseudocyst compressing the left atrium and the esophagus and causing dyspnea, palpitations, and emesis. Chest radiograph was non-diagnostic, esophagogastroduodenoscopy showed diffuse extrinsic compression of the distal esophagus and gastric corpus, but a definitive diagnosis was confirmed by computed tomography. We decided to perform surgery due to the recurrence of the pancreatic pseudocyst, a history of unsuccessful radiologically guided external drainage a few years earlier, and a very large diameter of the pseudocyst causing acute cardio-pulmonary distress syndrome...

A 22-year-old Asian woman presented with respiratory distress, cough, and wheezing for 1 week. Prior history included asthma and Turner syndrome. On presentation to the emergency department, the patient was hypotensive, tachycardic, tachypneic, with an oxyhemoglobin saturation in the mid 80% range while breathing ambient air. Chest radiograph revealed pulmonary vascular congestion and a left lower lobe infiltrate. Endotracheal intubation, mechanical ventilation, and vasopressors were initiated. Empiric therapy for community-acquired pneumonia was administered utilizing broad-spectrum intravenous antibiotics...

INTRODUCTION: The cardio-thoracic ratio (CTR) and the transverse cardiac diameter (TCD) on Plain chest radiography are the two parameters commonly used to diagnose cardiomegaly and heart disease. A CTR of greater than 50% on a PA film is abnormal and normally indicates cardiac or pericardial disease condition, whiles an increase of TCD from 1.5 to 2cm on two consecutive radiographs, taken at short interval, suggests possible cardiac pathology. The aim was to determine the suitability of using the same TCD and CTR to detect cardiomegaly for all age groups and genders respectively...

CONTEXT: The primary goal of septic shock management is optimization of organ perfusion, often at the risk of overloading the interstitium and causing pulmonary edema. The conventionally used end points of resuscitation do not generally include volumetric parameters such as extravascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI). AIMS: This study aimed to assess the prognostic value of EVLWI and PVPI by calculating their correlation with the severity of lung injury...

Lung ultrasound is increasingly being used by the bedside physicians to complement the findings of physical examination. Lung ultrasound is non-invasive, devoid of radiation exposure and can be performed rapidly and repeatedly as needed at bedside. The diagnostic accuracy of lung ultrasound for common conditions like pleural effusion, pneumothorax, pulmonary edema and pneumonia is superior to chest radiograph and is comparable to chest CT scan. Lung ultrasound is helpful to evaluate the progress of lung pathology and response to treatment, over time...

The most commonly ordered radiologic examination is the chest radiograph, and it is considered the gold standard for diagnosing pneumonia. For this reason, it is essential that radiologic technologists understand the disease and how it affects patients. This article discusses the anatomy of the lungs, along with the epidemiology, pathophysiology, risk factors, signs and symptoms, diagnosis, treatment, and complications of community-acquired pneumonia.

OBJECTIVE: Radiologic technologists may repeat images within a radiographic examination because of perceived suboptimal image quality, excluding these original images from submission to a PACS. This study assesses the appropriateness of technologists' decisions to repeat musculoskeletal and chest radiographs as well as the utility of repeat radiographs in addressing examinations' clinical indication. MATERIALS AND METHODS: We included 95 musculoskeletal and 87 chest radiographic examinations in which the technologist repeated one or more images because of perceived image quality issues, rejecting original images from PACS submission...
