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...

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...

Pulmonary embolism (PE) is a relatively common and potentially fatal pathology. Fear of missing the diagnosis is pervasive for physicians, including radiologists. However, as computed tomography pulmonary angiography technology and utilization have evolved over the years, we have gained an understanding that not all PEs are equal. As such, our interpretations of PE imaging studies must be enriched by this understanding and adapted to patient circumstances. Herein, we shine the light on overdiagnosis of PE, exploring the evidence, impact, costs, and consequences of overdiagnosis on the care of our patients...

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.

PURPOSE: Pulmonary hypertension (PH) parameters such as pulmonary artery or right ventricular size can be measured easily on computed tomography (CT). However, there are limited data on electrocardiographically (ECG) gated CT. We sought to determine age-specific and sex-specific normal reference values for PH parameters normalized by body surface area (BSA) using ECG-gated cardiac CT in a Chinese population. MATERIALS AND METHODS: In total, we enrolled 519 non-PH patients undergoing ECG-gated CT coronary angiography and measured PH parameters, including main pulmonary artery (MPA) and right pulmonary artery (RPA) diameters and distension, the ratio of MPA to ascending aorta (AAO) diameter (MPA/AAO), and the ratio of right ventricular to left ventricular diameter (RV/LV)...

Coronary computed tomography angiography (CCTA) is a validated technique for the evaluation of patients with suspected coronary artery disease, showing high accuracy compared with invasive coronary angiography and high negative predictive value. CCTA is also well positioned as a first-line test for the evaluation of stable chest pain. This purpose of this review is to examine the evidence behind CCTA in the setting of stable chest pain, with attention to 5 key strengths of a CCTA-based approach: (1) effective gatekeeping to cardiac catheterization, (2) selective discrimination for revascularization and tailored medical therapy, (3) advanced risk stratification, (4) improvement in outcomes, and (5) support from multisociety guidelines...

PURPOSE: To assess the prevalence of extracardiac findings (ECF) during cardiovascular magnetic resonance (CMR) examinations and their downstream effect on clinical management. MATERIALS AND METHODS: We retrospectively identified 500 consecutive patients. Trans-axial balanced steady-state free precession nongated images acquired from the upper thorax to the upper abdomen were evaluated independently by 2 radiologists. ECF were classified as nonsignificant (benign, with no need for further investigation), significant (mandatory to be reported/monitored), and major (clinically remarkable pathology, mandatory to be reported/investigated/treated)...

PURPOSE: This study aimed to assess the factors contributing toward accurate detection and erroneous interpretation of pulmonary embolism (PE). MATERIALS AND METHODS: Over 13 months, all computed tomography pulmonary angiography studies were retrospectively rereviewed by a chest radiologist. Two additional chest radiologists assessed cases with disagreement between the first interpretation and rereview. The number, extent, and location of PE and specialty training, experience, time of study, kV, resident prelim, use of iterative reconstruction, signal to noise ratio (SNR), and reports describing the study as "limited" were recorded...

The heart can manifest a spectrum of focal convexities that range from insignificant crypts and diverticula to clinically relevant aneurysms and pseudoaneurysms. The distinction of a clinically significant lesion from a minor focal convexity can be challenging. This article outlines the various types of focal convexities on the basis of location within the heart and discusses unique morphologic and functional features to further characterize these entities. We also highlight the most critical clinical consequences of cardiac aneurysms and pseudoaneurysms such as thromboembolic events, aneurysm ruptures, intracardiac shunting, hemopericardium, and arrhythmias...

Common variable immunodeficiency (CVID) is associated with significant chronic lung disease. The purpose of this paper was to describe the clinical, radiologic, and pathologic findings of CVID-associated lung diseases. These include airways' disease, interstitial lung disease, lymphoma, and mucosa-associated lymphoid tissue lymphoma. In addition, a genetic syndrome termed Kabuki syndrome results in CVID-like immune abnormalities. These patients may also present with CVID-associated lung disease. Awareness and precise identification of CVID-associated lung disease may allow for better assessment of prognosis and direction of therapy...
