Angiosarcoma is a rare soft tissue sarcoma that usually occurs in deep soft tissues, breast, spleen, liver, and bone. Primary thoracic parietal localization of angiosarcoma is rare and prognosis is poor. In this report, we present the CT and PET features of a patient with pseudomesotheliomatous angiosarcoma of the chest wall and pleura, which, to the best(More)
PURPOSE To determine the radiologic features, pathogenesis, and prognostic importance of sarcoidlike reaction in patients with malignancy. MATERIALS AND METHODS Radiographs and computed tomographic (CT) scans of the chests of 10 patients with known malignancy and either concurrent or subsequent development of noncaseating granulomas (NCG) were reviewed(More)
PURPOSE To evaluate the frequency and severity of pulmonary hemorrhage after transthoracic needle lung biopsy (TTLB) and assess possible factors associated with pulmonary hemorrhage. MATERIALS AND METHODS This retrospective study was approved by the institutional review board. The requirement to obtain informed consent was waived. Records from 1113(More)
OBJECTIVE The purpose of this article is to highlight the role of radiography, CT, PET/CT, and MRI in the diagnosis and management of chest wall lesions. Chest wall masses are caused by a spectrum of clinical entities. The lesions highlighted in this selection of case scenarios include neoplastic, inflammatory, and vascular lesions. CONCLUSION Imaging(More)
Medical 3-dimensional (3D) printing is emerging as a clinically relevant imaging tool in directing preoperative and intraoperative planning in many surgical specialties and will therefore likely lead to interdisciplinary collaboration between engineers, radiologists, and surgeons. Data from standard imaging modalities such as computed tomography, magnetic(More)
OBJECTIVE The purpose of our study was to assess the utility of performing routine pelvic and lower extremity CT venography (CTV) along with pulmonary CT angiography (CTA) in all patients evaluated for pulmonary embolism. MATERIALS AND METHODS Eight hundred twenty-nine consecutive patients (281 men and 548 women) underwent CTA-CTV for pulmonary embolism.(More)
Right ventricular (RV) dysfunction is an important marker to predict morbidity and mortality in patients with acute pulmonary embolism (PE) [1, 2]. Because it provides a cine assessment, echocardiography is the first-line method to evaluate RV dysfunction. However, since CT pulmonary angiography (CTPA) is the standard diagnostic modality for PE [3],(More)
The purpose of this study is to present the characteristic HRCT findings of the lung parenchyma in patients with proximal interruption of the right main pulmonary artery. HRCT findings of proximal interruption of the right pulmonary artery demonstrated reticular opacities, septal thickening, subpleural consolidation, cystic lung changes, and pleural(More)
Recent development of MR techniques has overcome many problems, such as susceptibility artifacts or motion artifact, allowing both static and dynamic MR lung imaging and providing quantitative information of pulmonary function, including perfusion, ventilation, and respiratory motion. Dynamic contrast-enhanced MR perfusion imaging is suitable for the(More)
RATIONALE AND OBJECTIVES The purpose was to evaluate clinical characteristics associated with low confidence in diagnosis of acute pulmonary embolism (PE) as expressed in computed tomography pulmonary angiography (CTPA) reports and to evaluate the effect of confidence level in PE diagnosis on patient clinical outcomes. MATERIALS AND METHODS This study(More)
