Dear AuntMinnie Member,
In patients with neurodeocrine tumors (NETs), liver metastases are an indicator for poor prognosis and significantly reduced chances of survival. However, a team of researchers from Germany reported at RSNA 2022 that PET/CT imaging with the radiotracer gallium-68 DOTATATE can detect more of these metastases than invasive biopsy.
As a result, the method may be able to reduce unnecessary biopsies and optimize patient management, according to the group. Our coverage of the study was the most popular story on AuntMinnie.com this week.
Other highly viewed stories in our Molecular Imaging Community includes articles on how 3D printing could actually enable increased production of molybdenum-99 and how PET/CT imaging with a boron-based radiotracer outperformed standard F-18 FDG for differentiating malignant from benign lesions.
CT lung cancer screening dose
Just how low a dose is too low for low-dose CT lung cancer screening? Some caution may be needed in pursuing ultralow-dose CT, if a study from Brazil is any indication.
In a presentation at RSNA 2022, researchers found that although ultralow-dose CT was effective for some results such as emphysema and nodules, it did lead to poor interreader agreement for significant findings such as consolidation and ground-glass opacity.
Photon-counting CT was one of the hot topics again at the RSNA meeting. For a status update, we spoke with Cynthia McCollough, PhD, of the Mayo Clinic in Rochester, MN. You can watch our video interview in the CT Digital Community.
Reimbursement Cuts
It's taken last-minute action in recent years by the U.S. Congress to mitigate the effects of statutory cuts to Medicare reimbursement. And it'll be needed again this year, as described in a recent column by Sandy Coffta of Healthcare Administrative Partners. Read her coverage to learn more about the potential impact on radiology.
Also, virtual radiology residency match interviews have saved medical students thousands of dollars, according to another study presented at RSNA 2022. You can find all the details in our Imaging Leaders Community.
