Published ahead-of-print in JTI are two new articles:

Jordan A. Zach and colleagues on behalf of the COPDGene Investigators have published "Current Smoking Status is Associated with Lower Quantitative CT Measures of Emphysema and Gas Trapping.” This original article describes the results of analysis of 6762 current and former smokers who underwent volumetric inspiratory and expiratory chest CT. The authors used an open-source quantitative CT software to determine the amount of emphysema and gas trapping in the study subjects. The authors found that current smokers had significantly more areas of lower attenuation (defined as <= -950 HU on inspiration and <= -856 HU on expiration) after adjusting for demographics and pulmonary function.

The second article is a symposium review article by Sandra Castaños Gutiérrez and colleagues entitled, “Current Concepts on Diagnosis and Prognosis of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia”. This article reviews the pathophysiology and genetics of ARVC/D and focuses primarily of the role of cardiac MRI in management with respect to diagnosis, prognosis, and therapy. Common pitfalls encountered on cardiac MRI than can result in a misdiagnosis of ARVC/D are also discussed.

Both articles are available to subscribers or can be purchased by nonsubscribers.

The September 2015 issue of JTI has been published on-line and in print.

Venkatesh Murugan and colleagues have published their review article, “Lung Cancer Screening: Computed Tomography Radiation and Protocols”, which provides some guidance for adjusting chest CT protocols to meet specifications for lung cancer screening.

Many new original articles have also been published:

  • “Semiautomatic Analysis on Computed Tomography in Locally Advanced or Metastatic Non-Small Cell Lung Cancer: Reproducibility and Prognostic Significance of Unidimensional and 3-dimensional Measurements” by Davide Colombi and colleagues

  • “Imaging Tumor Response and Tumoral Heterogeneity in Non–Small Cell Lung Cancer Treated With Antiangiogenic Therapy: Comparison of the Prognostic Ability of RECIST 1.1, an Alternate Method (Crabb), and Image Heterogeneity Analysis” by Connie Yip and colleagues

  • “The Pseudocavitation Sign of Lung Adenocarcinoma: A Distinguishing Feature and Imaging Biomarker of Lepidic Growth” by Tina Tailor and colleagues

  • “Core Lung Biopsy for Biomarker Analysis: Is There Increased Risk Compared With Conventional Biopsy?” By Sujay Sheth and colleagues

  • “Diagnostic Yield and Safety of Computed Tomography–guided Mediastinal Core Needle Biopsies” by Constance de Margerie-Mellon and colleagues

  • “Comparison of Digital Tomosynthesis and Chest Radiography for the Detection of Noncalcified Pulmonary and Hilar Lesions” by Angela Galea and colleagues

  • “Estimation of Pleural Fluid Volumes on Chest Radiography Using Computed Tomography Volumetric Analysis: An Update of the Visual Prediction Rule” by Joseph Mammarappallil and colleagues

Four new articles, two original articles and two symposium review articles, have been published ahead-of-print in JTI.

Tina Tailor and colleagues have published “The Pseudocavitation Sign of Lung Adenocarcinoma: A Distinguishing Feature and Imaging Biomarker of Lepidic Growth.” The authors’ retrospective review of 158 non-small cell lung carcinomas showed that the presence of pseudocaviation in a lesion occurs more commonly in adenocarcinomas, especially those demonstrating lepidic growth.

Eduardo Mortani Barbosa and colleagues report on their survey results regarding reporting of intensive care unit portable chest radiographs in “Optimization of Radiology Reports for Intensive Care Unit Portable Chest Radiographs: Perceptions and Preferences of Radiologists and ICU Practitioners.” Their results indicate that clinicians surveyed felt more strongly about the value of the reports compared to the radiologists surveyed, and that radiologists favor concise, structured reports while clinicians preferred more detailed reports.

The two symposium review articles focus on minimally invasive mitral valve repair. In their review article “Imaging in Minimally Invasive Mitral Valve Repair”, Stefanie Mangold and colleagues describe recent advances in mitral valve repair and discuss the role of pre- and post-treatment imaging. Chandra Dass and colleagues describe the role of imaging for surgical planning before minimally invasive mitral valve surgery in “Preprocedural Computed Tomography Evaluation for Minimally Invasive Mitral Valve Surgery: What the Surgeon Needs to Know.”

Monday, July 13, 2015

Published ahead of print in JTI are two new articles on transcatheter aortic valve replacement (TAVR), both part of an upcoming JTI symposium.

Julian Wichmann and colleagues have published “Transcatheter Aortic Valve Replacement: Imaging Techniques for Aortic Root Sizing”, a review article. This article describes current prostheses, aortic root sizing algorithms including CT and cardiac MRI. The authors also describe methods for reducing iodinated contrast volume.

Gilat Grunau and colleagues have published the review article “Clinical Aspects and Current Evidence Base for Transcatheter Aortic Valve Implantation”. This article reviews the clinical aspects of TAVR including how the procedure is performed, and published evidence on outcomes and complications is reviewed. Furthermore, the authors describe special clinical situations including diabetes and patients with previous coronary arterial bypass grafting.

The July 2015 issue of JTI has been published in print and on line.

The Expert Opinion feature asks whether or not there is still a role for filtered-back projection in cardiothoracic CT. Check out what our experts have to say!

Three new review articles are available to readers:

  1. “Diffuse parenchymal abnormalities in acutely dyspneic patients: a pattern-based approach” by Marie-Helene Levesque and colleagues

  2. “Acute thoracic findings in oncologic patients” by Brett Carter and Jeremy Erasmus

  3. Available for 1.5 hours of self-assessment – CME (SA-CME) credit is “Imaging evaluation of mediastinal masses in children and adults: practical diagnostic approach based on a new classification system” by Paul Thacker and colleagues.

Two original research articles are also available:

  1. “Prevalence of venoatrial compression by lymphadenopathy in sarcoidosis” by Matthieu Gomes and colleagues.

  2. “Enhancement characteristics of the computed tomography pulmonary angiography test bolus curve and its use in predicting right ventricular dysfunction and mortality in patients with acute pulmonary embolism” by Caiying Li and colleagues.

Web exclusive content includes:

  1. A pictorial essay entitled “Utility of low-dose high-pitch scanning for pediatric cardiac computed tomographic imaging” by Christopher Long and colleagues

  2. Abstracts from the joint meeting of the Fleischner Society and the European Society of Thoracic Imaging, which was held June 4-6. 2015 in Barcelona, Spain.
