Technique boosts x-ray CAD results for TB

Dutch researchers have developed an algorithm to improve the robustness of computer-aided detection (CAD) to identify tuberculosis (TB) on chest x-rays -- enabling CAD to significantly improve the detection of thoracic abnormalities.

Study questions evidence that screening reduces mortality

By AuntMinnie.com staff writers

Randomized controlled trials show that few of the currently available screening tests for major diseases where death is a common outcome have documented reductions in disease-specific mortality, according to a new study published online in the International Journal of Epidemiology.

Lung plus head/neck cancer screening delivers high yields

Head and neck cancer is too rare to screen for in the general population, but using CT to screen those who are also being checked for lung cancer draws a relatively high yield of malignancies, according to an analysis published online in Cancer.

ACS: Cancer deaths drop 22% over 2 decades

The American Cancer Society (ACS) recently reported that there has been a 22% drop in mortality from cancer in the U.S. over the past two decades, a decline that translates into the avoidance of over 1.5 million cancer deaths.

AJR: CT shows evidence of lung cancer spread via airways

New research with CT supports the hypothesis that lung adenocarcinoma may spread through the airways and not just through the blood. So-called aerogenous metastasis of lung cancer has implications for staging, management, and prognosis and may be underrecognized, the authors report in the American Journal of Roentgenology.

Chest CT referrals from x-ray yield high rate of abnormalities

Nearly half of patients who receive radiologist recommendations for chest CT to evaluate abnormal findings on chest radiography have clinically relevant findings at CT, including a substantial number of new malignancies, according to a new study in Radiology.

Nonsolid lung nodules found on CT screening harbor few cancers

Nonsolid nodules detected with CT lung cancer screening are often indolent, and even when they do harbor cancer, the long lead times before such nodules develop make it safe to follow them up less often, according to new long-term data presented at the RSNA 2014 meeting.

CT ties emphysema to mortality, independent of other risks

CT scans show that people with emphysema are at risk of earlier death than those without the disease, even if they have no evidence of chronic obstructive pulmonary disease or airflow obstruction, according to a study published on Monday in the Annals of Internal Medicine.
