Smoking-Related Interstitial Lung Disease and Emphysema.

Diagnosis and treatment of patients with smoking-related lung diseases often requires multidisciplinary contributions to optimize care. Imaging plays a key role in characterizing the underlying disease, quantifying its severity, identifying potential complications, and directing management. The primary goal of this article is to provide an overview of the imaging findings and distinguishing features of smoking-related lung diseases, specifically, emphysema/chronic obstructive pulmonary disease, respiratory bronchiolitis-interstitial lung disease, smoking-related interstitial fibrosis, desquamative interstitial pneumonitis, combined pulmonary fibrosis and emphysema, pulmonary Langerhans cell histiocytosis, and E-cigarette or vaping related lung injury.

Practice patterns in reporting interstitial lung abnormality at a tertiary academic medical center.

Purpose: Interstitial lung abnormality (ILA) is a common finding on chest CTs and is associated with higher all-cause mortality. The 2020 Fleischner Society position paper standardized the terminology and definition of ILA. Despite these published guidelines, the extent to which radiologists use this term is unknown.

How Does Pruning Impact Long-Tailed Multi-label Medical Image Classifiers?

Pruning has emerged as a powerful technique for compressing deep neural networks, reducing memory usage and inference time without significantly affecting overall performance. However, the nuanced ways in which pruning impacts model behavior are not well understood, particularly for , datasets commonly found in clinical settings. This knowledge gap could have dangerous implications when deploying a pruned model for diagnosis, where unexpected model behavior could impact patient well-being.

Screening Chest CT Prior to Allogenic Hematopoietic Stem Cell Transplantation.

Pulmonary complications constitute a major cause of morbidity and mortality in the post-allogenic hematopoietic stem cell transplantation (alloHSCT) period. Although chest X-ray (CXR) is customarily used for screening, we have used chest computed tomography (CT) scans. To characterize the prevalence of abnormalities and explore their impact on alloHSCT eligibility and outcomes post-transplantation, we conducted a retrospective analysis using real-world data collected at our center for adult patients who were evaluated for alloHSCT between January 2013 and December 2020 and identified 511 eligible patients.

Incidence, clinical associations and outcomes of intrathoracic complications with and without ARDS in COVID-19 pneumonia.

Purpose: To determine the incidence and clinical predictors of intrathoracic complications in COVID-19 patients, and the association with outcomes.

Methods: In this retrospective cross-sectional study, we included 976 patients (age 61 ± 17 years, 62% male) who tested positive for SARS-CoV-2 between March 3-April 4, 2020 and underwent chest imaging. 3836 radiographs from 976 patients and 105 CTs from 88 patients were reviewed for intrathoracic complications, including pneumothorax, pneumomediastinum, pneumopericardium, lobar collapse, pleural effusion, and pneumatocele formation.

Management of Incidental Pulmonary Nodules: Influencing Patient Care Through Subspecialized Imaging Review.

Objective: To evaluate whether thoracic radiologist review of computed tomography-detected incidental pulmonary nodules initially reported by non-thoracic imagers would change management recommendations.

Materials And Methods: The Radiology Consultation Service identified 468 computed tomography scans (one per patient) performed through the adult emergency department from August 2018 through December 2020 that mentioned the presence of a pulmonary nodule. Forty percent (186/468) were read by thoracic radiologists and 60% (282/468) were read by non-thoracic radiologists.

Imaging Utilization and Outcomes in Vulnerable Populations during COVID-19 in New York City.

Background: Coronavirus disease 2019 (COVID-19) affects vulnerable populations (VP) adversely.

Purpose: To evaluate overall imaging utilization in vulnerable subgroups (elderly, racial/ethnic minorities, socioeconomic status [SES] disadvantage) and determine if a particular subgroup has worse outcomes from COVID-19.

Materials/methods: Of 4110 patients who underwent COVID-19 testing from March 3-April 4, 2020 at NewYork-Presbyterian Hospital (NYP) health system, we included 1121 COVID-19 positive adults (mean age 59±18 years, 59% male) from two academic hospitals and evaluated imaging utilization rates and outcomes, including mortality.

Central paradiaphragmatic middle lobe involvement in nonspecific interstitial pneumonia.

Objectives: Nonspecific interstitial pneumonia (NSIP) lacks specific diagnostic guidelines or criteria for imaging diagnosis, and the need for more reliable computed tomography (CT) characterization remains. We hypothesized that central paradiaphragmatic middle lobe (ML) involvement is present in most patients with NSIP. The purpose of this study was to evaluate the prevalence of ML involvement and thus to assess its potential as a unique feature of NSIP.

Thoracic Manifestations of Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is one of the most common chronic systemic inflammatory diseases and the most common chronic inflammatory arthritis. Classically a progressive symmetric polyarthritis, RA is characterized by inflammation, erosions, bone loss, and joint destruction. Up to half of patients with RA exhibit extra-articular manifestations (EAMs), which may precede articular disease and are more common in patients with seropositive RA (patients with detectable serum levels of rheumatoid factor and/or anticitrullinated peptide antibodies).

A Case-Based Review of Vaping-Induced Injury-Pulmonary Toxicity and Beyond.

The last 10 years has seen a steady rise in the use of electronic cigarettes ("e-cigarettes" or ECIGs) or "vape pens." Though initially developed to assist with smoking cessation, use among adolescents has been particularly high. A concomitant rise in ECIG-related injuries disproportionately affecting young patients has been recognized.

Myocardial Infarction With Nonobstructive Coronary Arteries (MINOCA): Potential Etiologies, Mimics and Imaging Findings.

Myocardial infarction with nonobstructive coronary arteries (MINOCA) occurs when a patient presents with positive cardiac enzymes in the absence of obstructive atherosclerosis on coronary angiography. Several hypotheses for the pathogenesis of MINOCA have been suggested and multiple potential underlying etiologies have been reported. This review will outline the reported causes of MINOCA and associated major imaging features.

Isolated Cystic Lung Disease: An Algorithmic Approach to Distinguishing Birt-Hogg-Dubé Syndrome, Lymphangioleiomyomatosis, and Lymphocytic Interstitial Pneumonia.

Birt-Hogg-Dubé (BHD) syndrome, lymphangioleiomyomatosis (LAM), and lymphocytic interstitial pneumonia (LIP) frequently present as isolated cystic lung disease and can be challenging to distinguish. If imaging findings are otherwise unremarkable, the radiologist is unaided by ancillary CT findings in narrowing the diagnosis. We hypothesized that the distribution and morphologic features of lung cysts could be used to differentiate BHD syndrome, LAM, and LIP.

Congenital anomalies of the pulmonary arteries: an imaging overview.

Congenital pulmonary artery anomalies represent a diverse group of abnormalities, ranging from asymptomatic incidental findings to causes of sudden cardiac death. While some may be recognized in childhood, others may be found incidentally in adulthood. We review the clinical and imaging findings in patients with congenital anomalies of the pulmonary arteries, including valvular and perivavular anomalies as well as abnormal narrowing, course and communications of the pulmonary arteries.

Malignant Pleural Mesothelioma: Are There Imaging Characteristics Associated With Different Histologic Subtypes on Computed Tomography?

Objectives: Determine imaging characteristics specific to epithelioid (eMPM), sarcomatoid (sMPM), and biphasic (bMPM) subtypes of malignant pleural mesothelioma (MPM) on computed tomography.

Methods: Preoperative computed tomography scans of patients with MPM were retrospectively assessed for numerous features including primary affected side, volume loss, pleural thickness, pleural calcifications, pleural effusion, and lymphadenopathy.

Results: One hundred twenty-five patients with MPM were included.

Hepatic angiosarcomatous transformation of a mediastinal germinal cell tumor: A care case report.

Rationale: Mediastinal nonseminomatous germ cell tumor (NSGCT) is an uncommon entity. Metastatic hepatic sarcomatous transformation is rare.

Patient Concerns: We report a 24-year-old man with no previous related medical history presented with chest pain and left arm numbness.

Preliminary study of tumor heterogeneity in imaging predicts two year survival in pancreatic cancer patients.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers in the United States with a five-year survival rate of 7.2% for all stages. Although surgical resection is the only curative treatment, currently we are unable to differentiate between resectable patients with occult metastatic disease from those with potentially curable disease.

Rare case of pulmonary involvement in an adult with Kawasaki disease.

Kawasaki disease is an acute, self-limited, febrile vasculitis typically seen in early childhood. Pulmonary involvement is uncommon and is not part of the conventional diagnostic criteria. We add to the literature a unique case of a 22year-old male with Kawasaki disease and pulmonary involvement.

Fertility-sparing for young patients with gynecologic cancer: How MRI can guide patient selection prior to conservative management.

Historically, cancer treatment has emphasized measures for the "cure" regardless of the long-term consequences. Advances in cancer detection and treatment have resulted in improved outcomes bringing to the fore various quality of life considerations including future fertility. For many young cancer patients, fertility preservation is now an integral component of clinical decision-making and treatment design.
