By contrast, several studies have found almost one-half of normal chest radiographs at initial presentation disagree with clinical symptoms7,8,9,10. Because of its higher sensitivity, specificity, and speed, chest computed tomography (CT) has become more useful than RT-PCR in early detection, ...
Furthermore, patients were excluded if CT scans were made with a slice thickness >3 mm, or were limited by severe breathing artifacts or incomplete coverage of the lungs. Finally, patients with more than 15 pulmonary metastases (according to the initial visual assessment) were excluded to ...
that include the lungs, heart, and surrounding bones. This method gives precise images that help to determine the presence and extent of injury. Chest CT scanning with contrast gives an in-depth view of inside the chest. This multiple-angled X-ray technique takes many sharp images of the ...

CT with contrast was performed before invasive procedures. Depending on the results of these initial procedures an individual diagnostic plan was made involving a variety of invasive procedures such as bronchoscopy, transthoracic needle aspiration biopsy, endoscopic ultrasound, endobronchial ultrasound and/or...
