Computed Tomography Appearance of Uncorrected Congenital Heart Disease in Adults.

J Thorac Imaging 2019 Feb 7. Epub 2019 Feb 7.

Department of Radiology, University Hospital, Rutgers New Jersey Medical School, Newark, NJ.

The incidence of congenital heart disease (CHD) is about 4 to 10 per 1000 live births. While severe forms of CHD are usually diagnosed in infancy or childhood, milder and more survivable CHD may first manifest in the adult or may be discovered incidentally on imaging studies performed for other reasons. It is important to identify CHD in adults to implement appropriate treatment and prevent complications such as progression of pulmonary hypertension and development of heart failure. Read More

Noncontrast Chest Computed Tomographic Imaging of Obesity and the Metabolic Syndrome: Part II Noncardiovascular Findings.

J Thorac Imaging 2019 Jan 31. Epub 2019 Jan 31.

Departments of Radiology.

The purpose of this review article is to acquaint the reader with the current state of the art for the noncardiovascular imaging biomarkers of metabolic syndrome found on noncontrast computed tomography (NCCT) of the chest and their prognostic significance. Routine chest NCCT includes quantitative information with regard to tissue density and organ volumes in the neck, chest, and upper abdomen. The specific imaging biomarkers that may be seen in association with metabolic syndrome include low thyroid iodine organification, hepatic steatosis, sarcopenia (muscle volume and density), demineralization of the thoracic and upper lumbar vertebral bodies, loss of axial skeletal muscle mass, premature lung inflammation, and an increased deposition of subcutaneous and visceral fat.

Computed Tomography Imaging for Novel Therapies of Chronic Obstructive Pulmonary Disease.

J Thorac Imaging 2018 Dec 13. Epub 2018 Dec 13.

Department of Diagnostic and Interventional Radiology, University Hospital of Heidelberg.

Novel therapeutic options in chronic obstructive pulmonary disease (COPD) require delicate patient selection and thus demand for expert radiologists visually and quantitatively evaluating high-resolution computed tomography (CT) with additional functional acquisitions such as paired inspiratory-expiratory scans or dynamic airway CT. The differentiation between emphysema-dominant and airway-dominant COPD phenotypes by imaging has immediate clinical value for patient management. Assessment of emphysema severity, distribution patterns, and fissure integrity are essential for stratifying patients for different surgical and endoscopic lung volume reduction procedures.

Screening for Early Lung Cancer, Chronic Obstructive Pulmonary Disease, and Cardiovascular Disease (the Big-3) Using Low-dose Chest Computed Tomography: Current Evidence and Technical Considerations.

J Thorac Imaging 2018 Dec 13. Epub 2018 Dec 13.

Center for Medical Imaging North-East Netherlands (CMI-NEN), University Medical Center Groningen, University of Groningen.

Lung cancer, chronic obstructive pulmonary disease, and cardiovascular disease are highly prevalent in the general population and expected to cause most deaths by 2050. For these "Big-3," treatment might cure, delay, or stop the progression of disease at a very early stage. Lung nodule growth rate (a biomarker for lung cancer), emphysema/air trapping (a biomarker for chronic obstructive pulmonary disease), and coronary artery calcification (a biomarker for cardiovascular disease) are imaging biomarkers of early stages of the Big-3 that can be acquired with low-dose computed tomography (CT).

Computed Tomography and Magnetic Resonance Imaging of Cardiovascular Anomalies Associated With Turner Syndrome.

J Thorac Imaging 2018 Oct 29. Epub 2018 Oct 29.

Departments of Radiology.

Cardiovascular imaging plays a central role in the diagnosis, management, and follow-up of congenital and acquired cardiovascular disease in patients with Turner syndrome. Cardiovascular defects in this population may affect a single component of the cardiovascular system or exist in combination with other anomalies, and, they may present early in life or remain occult into adulthood. Careful screening and surveillance imaging are necessary for the early detection and management of cardiovascular defects, especially in cases wherein early intervention may be necessary to prevent a serious cardiovascular outcome.

Current Evidence in Cardiothoracic Imaging: Computed Tomography-derived Fractional Flow Reserve in Stable Chest Pain.

J Thorac Imaging 2019 Jan;34(1):12-17

Department of Cardiology, Aarhus University Hospital Skejby, Aarhus, Denmark.

High-accuracy diagnostic imaging is needed to diagnose and manage coronary artery disease as well as to allow risk stratification for future events. Advancements in multidetector computed tomography and image postprocessing allow for routine computed tomography coronary angiography to provide anatomic luminal assessment similar to invasive coronary angiography, and, similarly, computational fractional flow reserve derived from computed tomography facilitates determination of hemodynamically relevant stenosis comparable to invasive fractional flow reserve. In this review article, we describe the diagnostic performance and the potential impact of fractional flow reserve derived from computed tomography in clinical practice. Read More

An Update on the European Lung Cancer Screening Trials and Comparison of Lung Cancer Screening Recommendations in Europe.

J Thorac Imaging 2019 Jan;34(1):65-71

University Medical Center Groningen, Center for Medical Imaging-North East Netherlands, University of Groningen.

While lung cancer screening has been implemented in the United States, it is still under consideration in Europe. So far, lung cancer screening trials in Europe were not able to replicate the results of the National Lung Screening Trial, but they do show a stage shift in the lung cancers that were detected. While eagerly awaiting the final result of the only lung cancer screening trial with sufficient statistical power, the NELSON trial, a number of European countries and medical societies have published recommendations for lung cancer screening using computed tomography.

The Added Value of Computer-aided Detection of Small Pulmonary Nodules and Missed Lung Cancers.

J Thorac Imaging 2018 Nov;33(6):390-395

Department of Radiology, Mount Sinai School of Medicine, New York, NY.

Lung cancer at its earliest stage is typically manifested on computed tomography as a pulmonary nodule, which could be detected by low-dose multidetector computed tomography technology and the use of thinner collimation. Within the last 2 decades, computer-aided detection (CAD) of pulmonary nodules has been developed to meet the increasing demand for lung cancer screening computed tomography with a larger set of images per scan. This review introduced the basic techniques and then summarized the up-to-date applications of CAD systems in clinical and research programs and in the low-dose lung cancer screening trials, especially in the detection of small pulmonary nodules and missed lung cancers.

Are We Overdiagnosing Pulmonary Embolism? "No".

J Thorac Imaging 2018 Nov;33(6):348-349

Department of Thoracic Imaging, Hospital Calmette, CHRU et Université de Lille 2, Nord de France, Lille, France.

Diagnosis of acute pulmonary embolism currently relies on computed tomography angiography which is acknowledged as a powerful, noninvasive tool. The concept of overdiagnosis is counterbalanced by a series of unanswered questions regarding the natural history of acute pulmonary embolism and the missing links between acute and chronic thromboembolic disease. For numerous reasons, it is less than certain that this concept will survive. Read More

Radiology of Chronic Cavitary Infections.

J Thorac Imaging 2018 Sep;33(5):334-343

Pulmonary Section, Denver Veterans Affairs Medical Center.

Chronic cavitary lung disease is an uncommon manifestation of pulmonary infection, and is a pattern which worldwide is most commonly caused by reactivation tuberculosis. Other organisms, however, can cause similar radiologic patterns. Endemic fungi have long been recognized as potential causes of this pattern in North and South America, but the frequency with which these diseases present with chronic cavities in North America is relatively small.

Chronic Cavitary Infections Other than Tuberculosis: Clinical Aspects.

J Thorac Imaging 2018 Sep;33(5):322-333

Pulmonary Section, Denver Veterans Affairs Medical Center.

Lung cavitation may be due to infectious or noninfectious pathologic processes. The latter category includes nonmalignant conditions, such as granulomatosis with polyangiitis, and malignant conditions, such as squamous cell carcinoma of the lung. Infectious etiologies that produce lung cavitation usually cause chronic illness, although some, particularly pyogenic bacteria, may produce acute cavitary disease. Read More

J Thorac Imaging 2018 Sep;33(5):282-294

Hospital de Sant Pau, Universitat Autónoma de Barcelona, Barcelona, Spain.

Community-acquired pneumonia refers to an acute infection of the lung in patients who did not meet any of the criteria for health care-acquired pneumonia, and is associated with at least some symptoms of acute infection, accompanied by the presence of an acute infiltrate on a chest radiograph. Chest radiography remains an important component of the evaluation of a patient with a suspicion of pneumonia, and is usually the first examination to be obtained. The diagnosis of community-acquired pneumonia is based on the presence of select clinical features and is supported by imaging of the lung, usually by chest radiography. Read More

Clinical Approach to Community-acquired Pneumonia.

J Thorac Imaging 2018 Sep;33(5):273-281

Department of Pneumology, Hospital Clinic of Barcelona, IDIBAPS, University of Barcelona, Ciberes, Barcelona, Spain.

Community-acquired pneumonia (CAP) remains a major health problem worldwide. The incidence of pneumonia increases with both age and the presence of specific risk factors, which lead to increased health care costs. However, although there is some controversy over the observed trend in CAP mortality over recent decades, it is clear that mortality in CAP patients who require intensive care unit care remains high.

Imaging of Thoracoabdominal Aortic Aneurysms.

J Thorac Imaging 2018 Nov;33(6):358-365

Cardiothoracic Surgery, Weill Cornell Medicine, New York-Presbyterian Hospital, New York, NY.

Untreated thoracoabdominal aortic aneurysms are associated with an exceedingly high mortality rate, and surgery carries a high complication rate. Crawford's classification system of thoracoabdominal aortic aneurysms describes aneurysm morphology and stratifies patients on the basis of risk of major postoperative complications including mortality, spinal cord injury, and renal failure. Computed tomography and magnetic resonance angiography are essential for classifying thoracoabdominal aortic aneurysms and identifying other important features that impact prognosis and surgical management.
