Effective Dose Estimations for Helical Computed Tomography in Lung Cancer Screening

Lung Cancer Screening by Helical Computed Tomography

Low-dose computed tomography lung cancer screening.

Lung cancers, primarily caused by tobacco smoking, are the leading cause of cancer deaths in the United States and around the world. Screening of select high-risk patients using low-dose helical computed tomography (LD-CT) has been shown to reduce lung cancer mortality by 20% compared with chest radiography. However, because there are risks to LD-CT lung cancer screening, it should be performed...

Overview of observational studies of low-dose helical computed tomography screening for lung cancer.

OBJECTIVE Lung cancer is a substantial public health problem in Western countries. Evidence from previous controlled trials of chest radiography and sputum cytology does not support lung cancer screening, but computed tomography (CT) screening has recently emerged as a more sensitive screening tool. For the present article, the available observational studies of low-dose helical CT screening fo...

Screening for lung cancer with low-dose spiral computed tomography.

Studies suggest that screening with spiral computed tomography can detect lung cancers at a smaller size and earlier stage than chest radiography can. To evaluate low-radiation-dose spiral computed tomography and sputum cytology in screening for lung cancer, we enrolled 1,520 individuals aged 50 yr or older who had smoked 20 pack-years or more in a prospective cohort study. One year after basel...

Screening for lung cancer using low dose computed tomography.

Screening for lung cancer with low dose computed tomography can reduce mortality from the disease by 20% in high risk smokers. This review covers the state of the art knowledge on several aspects of implementing a screening program. The most important are to identify people who are at high enough risk to warrant screening and the appropriate management of lung nodules found at screening. An acc...
