Problems of screening with CT are the excessive number of false positive findings, costs, radiation burden and from a global point of view shortage of CT capacity. In contrast, chest radiography could be an ideal screening tool in the early detection of lung cancer. It is widely available, ...
Up to one-fourth of all people with lung cancer may have no symptoms when the cancer is diagnosed. These cancers usually are identified incidentally when achest X-rayis performed for another reason. The majority of people, however, develop symptoms. The symptoms are due to direct effects of ...

With the release of the survival results from the NELSON lung cancer screening trial there is now additional evidence that low-dose computed tomography (LD
In the past studies using sputum cytology and chest radiography have failed to demonstrate any reduction in lung cancer mortality through screening. One of the reasons is probably the relatively poor sensitivity of both these tests in early tumours. Low radiation dose computed tomography (CT) has ...
Having many anatomical and molecular subtypes, cancer is a group of heterogeneous diseases that can affect almost every part of the body, each requiring specific diagnostic and management strategies. Screening of cancers aims at identifying cancers or pr
In the newly released Lung-RADS 2022 classification system for computed tomography (CT) lung cancer screening, the American College of Radiology (ACR) has noted a variety of updates including new classification criteria for atypical pulmonary cysts and airway nodules, time intervals for nodule grow...

CT Randomized clinical trial During the last decade the advent of low dose multislice computed tomography (CT) scanning has generated a widespread interest in lung cancer screening.1 Early observational reports stated that lung cancer could be detected in early stages in 85% of the cases2 and su...
CT scans provide much more detailed images than X-rays, and while no major medical group recommends any type of routine lung cancer screening, several are preparing new guidelines. Screening refers to routine tests in people without symptoms; doctors say chest X-rays are still useful to help di...
