Week in review: CT ups brain cancer risk in children? | RSNA 2022: Predictions vs. reality | FDG uptake in vaccinated patients

Dear AuntMinnie Member,

Our most popular story on AuntMinnie.com this week featured coverage of research analyzing the potential risk of radiation dose from CT scans in pediatric patients. In a study that included data from over 650,000 patients from nine countries and 276 hospitals, a team from Germany concluded that radiation exposure from CT increased the risk of brain cancer in children by up to fivefold, depending on the level of exposure.

As a result, the authors believe that it's crucial to track children's radiation exposure from CT scans. You learn more in our article or by stopping by our CT Community.

RSNA 2022: Predictions vs. reality

Although some trends at the RSNA meeting can be easy to forecast, there are always a few surprises each year. Signify Research published some predictions prior to the show and then assessed how they turned out. How did they do? Find out how they did in a column by Steve Holloway.

Speaking of the RSNA meeting, another popular article in our Imaging Leaders Community this week featured a video interview in Chicago with Sandy Coffta of Healthcare Administrative Partners. In the short conversation, Coffta shared her thoughts on the most pressing practice management issues facing radiology today.

FDG uptake in vaccinated patients

It's a known phenomenon that cancer patients who have received COVID-19 vaccines can experience F-18 FDG radiotracer uptake not caused by malignancy in the lymph nodes on PET/CT scans. In a presentation at RSNA 2022, a team of researchers found that the increased uptake in lymph nodes was evident in over 20% of cases.

Based on these results, the researchers recommended that patients with cancer that has a propensity to spread to lymph nodes should receive COVID-19 vaccines in the hip or arm contralateral to sites suspected of cancer. Get all of the details in our coverage.

In other popular articles in our Molecular Imaging Community, researchers have also found that whole-body PET imaging can help clinicians to visualize how patients may respond to immune inhibitor therapy. Also, PET scans prior to breast cancer surgery show that patients with higher levels of visceral adipose tissue are significantly more at risk for tumor recurrence.
