ARRS: Diagnostic breast tomo reduces need for US, biopsies
May 5, 2014 -- Using breast tomosynthesis in diagnostic workup -- specifically, with one- or two-view focal asymmetries found at screening mammography -- reduces ultrasound use and leads to fewer biopsies compared to diagnostic mammography alone, according to research presented at the American Roentgen Ray Society (ARRS) meeting in San Diego.  Discuss
Brassieres help cut chest CT radiation dose
May 5, 2014 -- Wearing a bra during a chest CT scan can significantly reduce dose to radiosensitive tissues by holding breast tissue within the lower-dose region created by tube-current modulation techniques, concludes a new study in the May issue of the American Journal of Roentgenology.  Discuss

AATS: Breath test tops PET for lung cancer detection
May 2, 2014 -- TORONTO - A breath test that analyzes chemical compounds could distinguish between malignant and benign tumors in the lung, according to data presented at the American Association for Thoracic Surgery (AATS) meeting. Early research indicates the test has better specificity than PET.  Discuss
Medicare panel raises doubts about CT lung cancer screening
May 1, 2014 -- Members of a Medicare advisory panel expressed a range of doubts about the benefits of CT lung cancer screening in a meeting on April 30 in Baltimore, giving screening low confidence scores. The question now becomes how the mostly negative panel meeting will shape the debate about Medicare reimbursement over the next six months.  Discuss
AATS: Is CT really better than x-ray for monitoring NSCLC patients?
May 1, 2014 -- TORONTO - There is no survival advantage to using CT over chest x-ray when monitoring patients who have undergone resection for pathologic stage I non-small cell lung cancer (NSCLC), according to a retrospective analysis presented at the American Association for Thoracic Surgery (AATS) annual meeting.  Discuss
MEDCAC panel shows low confidence in CT lung screening
April 30, 2014 -- CT lung cancer screening for high-risk individuals in the Medicare program received a vote of low confidence by a panel of medical experts meeting in Baltimore today. The vote seriously weakens the case for establishing Medicare payment for low-dose CT lung cancer screening.  Discuss
MRI shows that diabetes leads to loss of brain volume
April 30, 2014 -- MRI results suggest that the longer a patient has type 2 diabetes, the more brain volume is lost, according to research published online April 29 in Radiology. This was especially true for gray matter, which is associated with speech, motion, and memory.  Discuss
