PET/CT predicts brain tumors in melanoma patients
PET/CT scans have the potential to predict brain metastasis in melanoma patients, according to a study published December 26 in Cancers.
In a retrospective study, a team at the University Hospital Salzburg in Austria studied baseline F-18 FDG-PET/CT imaging parameters in patients with melanoma and found they were associated with the development of metastatic brain tumors.
“In melanoma patients, identification of those who are at higher risk of brain metastasis occurrence can be crucial as subsequent surveillance and even prophylactic treatment options can be provided,” wrote lead author and nuclear medicine physician...

New portable PET scanner tested in humans
In this study, they aimed to establish the feasibility of the approach using an experimental scanner called CerePET (Brain Biosciences, Rockville, MD).Each of the 20 healthy volunteers underwent dynamic F-18 FDG imaging with both scanners one to 154 days apart. Standard radiotracer uptake values (SUV) in brain tissue and rates of glucose metabolism (CMRglu) were quantified and compared between the scanners at regional and voxel levels.According to the findings, outcome measures were well correlated, the group wrote. Specifically, correlation coefficients between the imaging sets across participants were 0.83 ± 0.07 fo...

Intention to leave position higher among academic radiologists
Radiology is among medical specialties at higher risk of physician turnover, according to research published on December 15 in JAMA Network Open. A team led by Dr. Jennifer Ligibel from the Dana-Farber Cancer Institute in Boston found that academic radiologists have a higher-than-average rate of intention to leave their institutions. However, professionals in nuclear medicine and neuroradiology had the lowest rates. “Burnout, lack of professional fulfillment, and other well-being factors were associated with intention to leave, suggesting the need for a comprehensive approach to reduce physician turnover,” the Ligib...

PET/MRI reveals separate Alzheimer ’s biomarkers in single scan
A PET radiotracer for diagnosing Alzheimer’s disease may also be used to measure vascular brain changes in patients during PET/MRI scans, according to a study published December 7 in the Journal of Nuclear Medicine.
The finding suggests that hybrid PET/MRI can provide a more comprehensive picture of brain pathology involved in cognitive decline, noted first author Ates Fettahoglu, an undergraduate researcher at Stanford University in Stanford, CA, and colleagues.
“Two important biomarkers may be measured in a single session in participants with memory concerns, enabling improved characterization of dementia pathophys...

ChatGPT tested on nuclear medicine cases
ChatGPT shows potential for diagnosing nuclear medicine cases, yet needs further development before it can be implemented in practice, according to a study presented November 28 at RSNA in Chicago.
Gillean Cortes, DO, a resident at the University of California, Irvine presented a study that put ChatGPT-3.5 and ChatGPT-4 to the test on nuclear medicine differential diagnoses cases transcribed from two textbooks. The chatbot versions achieved accuracies of 60% and 70%, but were prone to “hallucinations,” Cortes noted.
“While ChatGPT has shown some potential in generating accurate diagnoses, this technology requires...

New CT, MR scanners and AI top GE HealthCare highlights at RSNA 2023
CHICAGO -- GE HealthCare (GEHC) brought new CT and MRI scanners and a range of AI software applications to McCormick Place for RSNA 2023. CT In CT, GEHC shined the spotlight on its Revolution Ascend scanner, which was first introduced at ECR in March. With onsite detector upgrades, Ascend can be upgraded from a 20-mm coverage system for routine scanning to a 40-mm coverage system that delivers better low-contrast detectability, according to the vendor. The scanner also comes with True Enhance DL, an AI-based application that generates deep learning-based monochromatic-like images from a single-energy x-ray acquisition....

PET tracer shows promise in prostate cancer patients
CHICAGO – Gallium-68 (Ga-68) RM2-PET/MRI is better than MRI alone for detecting relapse in prostate cancer patients, according to research presented November 26 at RSNA 2023.
Moreover, the approach could help detect disease that other effective prostate cancer PET radiotracers may miss, said Heying Duan, MD, a nuclear medicine research scientist at Stanford University, during a November 26 scientific session.
“You've hear a lot about PSMA. I wanted to introduce a new player in the game: gallium-68 GRPR antagonist,” Duan told attendees, during a scientific session on prostate cancer imaging.
