JAMA IM: Imaging lands high on list of low-value procedures
A new list of 26 low-value medical procedures published in JAMA Internal Medicine includes a dozen imaging exams. The exams -- defined as procedures that cost a lot of money without yielding significant benefits -- could be costing Medicare as much as $8.5 billion a year, according to the authors.

Brassieres help cut chest CT radiation dose
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.

Medicare panel raises doubts about CT lung cancer screening
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.

MEDCAC panel shows low confidence in CT lung screening
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.

PET/CT reveals new infections in ICU patients
By Will Morton
F-18 FDG-PET/CT is a valuable approach for diagnosing unknown infections in intensive care unit (ICU) patients.
February 21, 2025
There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis. This is an illustrative example of a relevant dissemination investigation.
