Published ahead-of-print in JTI is an original article by Dr. Sujay Sheth and colleagues comparing risk from core lung biopsy for biomarker analysis versus conventional biopsy. The study cohort comprised 200 patients, 23 of whom underwent core biopsy for biomarker analysis. Subjects in the biomarker biopsy arm had a mean of 5.1 core samples compared to 2.9 core samples for the control arm. The pneumothorax rates between the two arms were not statistically different with 30.4% in the biomarker group and 37.6% in the control group. Furthermore, rate of pleural drainage catheter placement were not significantly different between the groups at 16.8% for the control group and 8.7% for the biomarker group. The authors conclude that lung core needle biopsy for biomarker assessment, which typically requires more cores, is not associated with increased complication rate as compared to standard biopsy technique.

The May 2015 issue of JTI has been published in print and on line. This issue includes a symposium on cardiothoracic emergency imaging, guest edited by Drs. Sanjeev Bhalla and Ioannis Vlahos. The symposium includes the following review articles:
- “Coronary Computed Tomography Angiography for the Assessment of Acute Chest Pain in the Emergency Department: Evidence, Guidelines, and Tips for Implementation” by Dr. Alan Ropp and colleagues
- “Diagnosing Acute Pulmonary Embolism With Computed Tomography: Imaging Update” by Dr. Anand Devarak and colleagues
- “Acute Aortic Syndromes: Current Status” by Drs. Carole Ridge and Diana Litmanovich
- “Acute Traumatic Aortic Injury: Practical Considerations for the Diagnostic Radiologist” by Dr. Constantine Raptis and colleagues.
This issue’s Expert Opinion question focuses on how and when to perform CT myocardial perfusion imaging.
Also included in this issue is an original article entitled “Left Atrial Transverse Diameter on Computed Tomography Angiography Can Accurately Diagnose Left Atrial Enlargement in Patients With Atrial Fibrillation” by Dr. Sahand Sohrabi and colleagues.
Web exclusive content in this issue includes the next installment in Signs in Cardiopulmonary Imaging on the luftsichel sign by Drs. Kevin Day and Isabel Oliva. Other web exclusive content includes the ACR Appropriateness Criteria® Acute Respiratory Illness in Immunocompromised Patients by Dr. Darel Heitkamp and colleagues and the scientific and educational abstracts from the 2015 Society of Thoracic Radiology annual meeting and postgraduate course.

Published ahead-of-print in JTI are two new symposium review articles:
Drs. Brett Carter and Jeremy Erasmus from MD Anderson Cancer center have authored a review article entitled, “Acute Thoracic Findings in Oncologic Patients”. Their review article covers a variety of topics including drug toxicity, pulmonary infections, pulmonary embolism, superior vena cava syndrome, cardiac tamponade, massive hemoptysis, acute mediastinitis, and spinal cord compression.
Dr. Constantine Raptis and colleagues from Mallinckrodt Institute of Radiology at Washington University in St. Louis have written a review article entitled “Acute Traumatic Aortic Injury Practical Considerations for the Diagnostic Radiologist”. The authors review both chest radiographic and CT findings of traumatic aortic injury as well as discuss potential pitfalls encountered on CT as well as proper reporting of the injury, so as to best communicate the results with referring physicians.

The Centers for Medicare & Medicaid Services (CMS) has approved the American College of Radiology's (ACR) Lung Cancer Screening Registry. The ACR anticipates the registry will be open for registration in May 2015. Radiologists providing lung cancer screening CT for Medicare beneficiaries are required to participate in an approved registry.
More information on the ACR registry can be obtained here.
Also, we encourage you to participate in the upcoming STR course "The Essentials of CT Screening for Lung Cancer” on March 14, 2015. Registration for the live-streamed virtual course is open through March 13, 2015

The March 2015 issue of JTI has been published on-line and in print. This issue includes the very timely Lung Cancer Screening symposium guest edited by Dr. Caroline Chiles. This symposium includes seven exciting review articles covering the different aspects of lung cancer screening with low-dose CT.
- William C. Black
“Computed Tomography Screening for Lung Cancer in the National Lung Screening Trial: A Cost-effectiveness Analysis”
- Martin C. Tammemägi
“Application of Risk Prediction Models to Lung Cancer Screening: A Review”
- Marjolein A. Heuvelmans et al.
“Contributions of the European Trials (European Randomized Screening Group) in Computed Tomography Lung Cancer Screening”
- Takeshi Nawa et al.
“Low-dose Computed Tomography Screening in Japan”
- Brady J. McKee et al.
“Low-dose Computed Tomography Screening for Lung Cancer in a Clinical Setting: Essential Elements of a Screening Program”
- Geoffrey D. Rubin
“Lung Nodule and Cancer Detection in Computed Tomography Screening”
- Brian J. Bartholmai et al.
“Pulmonary Nodule Characterization, Including Computer Analysis and Quantitative Features”
In addition to the symposium article, this issue includes an original research study by Hannah Milch et al. “Computed Tomography Screening for Lung Cancer:
Preliminary Results in a Diverse Urban Population”. This screening study performed in New York City (the Bronx) and included 320 subjects, all of whom met National Lung Screening Trial enrollment criteria. This study focused on feasibility of introducing lung cancer screening in an ethnically diverse and poor population that struggles with high rates of obesity, HIV infection, and tuberculosis relative to the subjects in the NLST. The authors report a 2.2% (7/320) prevalence of lung cancer and a 78% (7/9) true positive rate for screening CT scans. Future work will determine whether any mortality benefits derive from screening this population.
