Chest Imaging
Special Issue: Chest Imaging 2021
Reviewing over the journals published every month from the world on topics in chest imaging, we may feel like more than 60 % of the articles are dealing with COVID-19 issue, the most pressing threat to human life and social activities in the world. As of the beginning of December 2020, EJR Open has already published 8 articles on COVID-19 pneumonia and one article in mammography for the second wave of COVID-19. However, it is probably also important to continue to work on diverse research activities broadly including topics outside of COVID-19.RETRACTED: Connective tissue disease-related interstitial lung disease (CTD-ILD) and interstitial lung abnormality (ILA): Evolving concept of CT findings, pathology and management

A micro-CT system was developed using a 36M-pixel digital single-lens reflex camera as a cost-effective mode for large human lung specimen imaging. Scientific grade cameras used for biomedical x-ray imaging are much more expensive than consumer-grade cameras. During the past decade, advances in image sensor technology for consumer appliances have spurred the development of biomedical x-ray imaging systems using commercial digital single-lens reflex cameras fitted with high megapixel CMOS image sensors.Projected lung areas using dynamic X-ray (DXR)
Pulmonary function tests (PFTs) provide the useful information about detection as well as characteristics or severity of lung disease. Forced vital capacity (FVC) have played an important role for the diagnosis of idiopathic pulmonary fibrosis (IPF) for many years. Patients can be diagnosed as interstitial lung disease if percent vital capacity (%VC) is lower than 80 %. It also correlates with a poor outcome in patient with IPF [1,2]. Forced expiratory volume in one second (FEV1) is also an important predictor in PFTs, especially for screening of chronic obstructive pulmonary disease (COPD).Subsolid pulmonary nodules: Controversy and perspective
Subsolid pulmonary nodules, which comprise pure ground glass and part-solid nodules, are commonly identified incidentally or as part of lung cancer screening. Our detection of subsolid nodules has grown dramatically over the last decade as thin section CT has become widely available. Additionally, our understanding of these nodules has progressed recently with the updated classification of lung adenocarcinoma in 2011 [1]. Subsolid nodules present a particular dilemma for radiologists and clinicians, as they have a higher rate of malignancy than solid nodules but, when malignant, demonstrate indolent behavior compared to solid lung cancers.Simple quantitative chest CT for pulmonary edema
Pulmonary edema is one of the most common entities that is encountered on routine chest imaging in both the inpatient and outpatient settings. Cardiogenic pulmonary edema is commonly caused by acute decompensated heart failure. The chest x-ray (CXR) is one of the most frequently utilized noninvasive diagnostic tests ordered to confirm or rule out pulmonary edema. CXR assessment of pulmonary edema has been shown to correlate with volume status, total blood volume [1–3], and other indicators of heart failure [4].Pulmonary Edema: A Pictorial Review of Imaging Manifestations and Current Understanding of Mechanisms of Disease
Pulmonary edema is a common clinical entity caused by the extravascular movement of fluid into the pulmonary interstitium and alveoli. The four physiologic categories of edema include hydrostatic pressure edema, permeability edema with and without diffuse alveolar damage (DAD), and mixed edema where there is both an increase in hydrostatic pressure and membrane permeability. As radiographic manifestations and etiologies are varied, an appreciation for both the common and uncommon manifestations and causes of pulmonary edema is essential for accurate diagnosis.Contribution of FDG-PET/CT to the management of esophageal cancer patients at multidisciplinary tumor board conferences
A multidisciplinary team approach to the management of esophageal cancer patients leads to better clinical decisions.Pleuroparenchymal fibroelastosis (PPFE)-like finding on CT in daily practice ―prevalence and serial changes
To characterize the prevalence of PPFE (pleuroparenchymal fibroelastosis)-like finding on CT in daily practice and to identify the risk factors for its progression.Influenza H1N1 virus-associated pneumonia often resembles rapidly progressive interstitial lung disease seen in collagen vascular diseases and COVID-19 pneumonia; CT-pathologic correlation in 24 patients
To describe computed tomography (CT) findings of influenza H1N1 virus-associated pneumonia (IH1N1VAP), and to correlate CT findings to pathological ones.Pleuroparenchymal fibroelastosis-like lesions in patients with interstitial pneumonia diagnosed by multidisciplinary discussion with surgical lung biopsy
The present study aimed to evaluate the significance of Pleuroparenchymal fibroelastosis (PPFE)-like lesions in predicting prognosis in patients with chronic interstitial pneumonia (IP).
