SPECT shows causes of accelerated brain aging
Abusing marijuana can add years to your brain's age. And so can bipolar disorder, schizophrenia, and a number of other factors, according to a study published online August 3 in the Journal of Alzheimer's Disease. Researchers using SPECT found evidence of accelerated brain aging among people with various disorders and behaviors.

MRI links lifestyle factors to stroke, dementia risk
Using MRI, researchers found that lifestyle factors can increase the risk of stroke and dementia later in life among young adults with no clinical evidence of cerebrovascular disease and a seemingly healthy cardiovascular risk profile. The study was published in the August 21 issue of the Journal of the American Medical Association.

Nuclear medicine duties not always shared equally
What's in a name? Apparently a lot when it comes to nuclear medicine. Physicians who identify themselves as nuclear medicine specialists devote at least 90% of their time to nuclear medicine duties, while most who call themselves nuclear radiologists or nuclear cardiologists devote 10% or less, according to a study published online August 7 in the American Journal of Roentgenology.

Studies question link between contact sports and CTE
Are concerns about the brain health of professional athletes who played contact sports overblown? That's the implication of a new study that found no signs of brain abnormalities on MRI scans of former hockey and football players that would suggest the presence of chronic traumatic encephalopathy (CTE).

FES-PET enhances treatment for metastatic breast cancer
By identifying differences in estrogen receptor expression through PET imaging with the tracer F-18 fluoroestradiol (FES), clinicians can better direct treatment for patients with metastatic breast cancer, according to a Dutch study published in the August issue of the Journal of Nuclear Medicine.

Strongly worded PET/CT reports influence follow-up
When radiologists use strong, specific follow-up recommendations in FDG-PET/CT reports, referring physicians are more likely to follow their advice -- and find cancers, according to a Dutch study published online July 29 in the Journal of the American College of Radiology.

Who reads lower-extremity MRI exams and why?
Most lower-extremity MRI exams are still interpreted by radiologists, but those that are read by nonradiologists are more likely to have been performed during the week and to be less complex cases, according to a study published online July 31 in the American Journal of Roentgenology.

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.
