December 20, 2013More than 18% of all lung cancers detected by low-dose computed tomography (CT) appeared to represent an overdiagnosis, according to a recently published study.
Reduced reimbursement for imaging may negatively impact patient outcomes
December 18, 2013Drastic reimbursement cuts for image-guided breast biopsies, and other medical imaging techniques in the 2014 Medicare Fee Schedule Final Rule, may further reduce women's access to mammography and other breast cancer services.

Overdiagnosis of thyroid cancer linked to new imaging methods
August 29, 2013There has been increasing incidence of small and indolent thyroid cancer but mortality rate has been stable since 1979.
Lung screening payoff low among low-risk patients
August 07, 2013
CT less effective preventing low-risk lung cancer mortality
July 18, 2013Low-dose CT screening for lung cancer prevents very few deaths among those at lowest risk.
PET improves survival in limited-stage lung cancer
July 17, 2013Persons with limited-stage small cell lung cancer (LS-SCLC) exhibited better disease control and survival when staged with positron emission tomography (PET) than did patients who did not undergo staging with PET.

Parental concern about CT scan cancer correlation
July 08, 2013About half of parents were aware of malignancy risks associated with computed tomography (CT) scans before emergency department disclosures.
Digital chest tomography may be first stop in lung cancer screening
June 19, 2013Digital chest tomosynthesis holds promise as a first-line tool for lung cancer screening, according to the baseline results of a single-arm, observational study.
Twice as many lung cancers detected by CT as by X-ray at initial screening
June 12, 2013Centers in the United States can achieve a 20% reduction in lung cancer mortality with low-dose computed tomography (LDCT) versus chest X-ray (CXR) screening that was previously reported by the National Lung Screening Trial (NLST).

AATS: MnDCT better than chest x-ray at detecting lung cancer
May 08, 2013MnDCT has similar radiation to X-ray but greater sensitivity for detecting new and recurrent cancer.
