ASTRO: AI's rad therapy future is in predicting outcomes
SAN ANTONIO - Radiation oncology is already putting artificial intelligence (AI) to work by using the technology for automating mundane tasks. But AI's real value will come when it is able to accurately predict patient outcomes, according to a Sunday talk at the American Society for Radiation Oncology (ASTRO) annual meeting.

Study gives all-clear for skin cream during radiation therapy
It's OK for patients scheduled for radiation therapy to apply topical treatments such as skin cream in moderation before their procedures, according to a study published October 16 in JAMA Oncology. That's good news for the many patients who want to use skin cream to counter skin rashes or burns caused by radiation treatments.

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.
