RATIONALE: As pleural plaque has been reported as a risk factor in the occurrence of lung cancer and mesothelioma, a reproducible and precise method of measurement of pleural plaque volume (PPV) is needed to further describe these relationships. The aim of the study was to assess the reproducibility of a 3-dimensional computed tomography (3D-CT) volumetric analysis of PPV in patients with occupational exposure to asbestos. MATERIAL AND METHODS: A total of 28 patients were retrospectively randomly selected from the multicenter APEXS (Asbestos Post Exposure Survey) study, which was held between 2003 and 2005...

PURPOSE: The purpose of this study was to prospectively evaluate the feasibility of detecting calcified aortic plaques in apolipoprotein E knockout (ApoE-KO) mice using a state-of-the-art human computed tomography (CT) system. MATERIALS AND METHODS: Eleven ApoE-KO and 9 wild-type mice, all male, were examined in this study. After intraperitoneal injection of 6.6% ketamine all mice underwent 2 ultra-high-resolution CT protocols on a third-generation dual-source CT system at 120 kVp and 130 kVp tube voltage, both performed with a tube current time product of 1300 mAs...

Hibernomas are rare benign soft tissue tumors derived from brown fat. This case report describes an axillary hibernoma with intrathoracic extension, presenting as a thoracic outlet syndrome. A multimodality imaging series illustrates the classic radiologic features of hibernoma as well as its highly unusual pattern of growth. The latter resulted in TOS with vascular displacement and osseous remodeling, features that are generally absent in lipomatous masses. Detailed preoperative imaging allowed to plan a single surgical procedure in which an extrathoracic axillary approach was combined with intrathoracic video-assisted thoracic surgery...

PURPOSE: The prognostic value of vascular calcifications as well as of regional fat depots has been reported separately, in population-based studies, and using gated-computed tomography (CT) examinations. We, therefore, explored the interplay and prognostic value of vascular calcifications and adipose tissue depots assessed during conventional nongated chest CT. MATERIALS AND METHODS: We enrolled a consecutive series of 1250 patients aged between 35 and 74 years who underwent clinically indicated chest CT scans...

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...

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...

Cardiac masses encountered on imaging may present a diagnostic dilemma when discovered incidentally, or even when they serve as the principal reason for the examination. In this review, we present an algorithmic approach for assessing cardiac masses by integrating clinical information with radiologic findings to reach a specific diagnosis or a narrow differential diagnosis.

Proximal interruption of the pulmonary artery (PIPA) is an uncommon developmental anomaly resulting in underdevelopment of the proximal portion of the pulmonary artery with preservation of the intrapulmonary segments. Clinical presentation ranges between an asymptomatic incidental finding to massive hemoptysis. When findings suggestive of PIPA are present radiographically, the diagnosis of PIPA can be definitively diagnosed with computed tomography or magnetic resonance pulmonary angiography. Other imaging modalities, such as nuclear perfusion scan and catheter angiography can help in the diagnosis...

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: 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...
