3 days ago | auntminnie.com | Will Morton

4D flow MRI has revealed impaired cardiac blood flow in patients with chronic obstructive pulmonary disease (COPD), according to a May 12 presentation at at the International Society for Magnetic Resonance in Medicine (ISMRM) annual meeting in Honolulu, HI.

MRI has revealed that dysfunction in the brain’s glymphatic system accelerates brain aging in patients with ischemic stroke, according to research to be presented May 13 at the International Society for Magnetic Resonance in Medicine (ISMRM) 2025 meeting in Honolulu.
PET/MRI reveals how brain stimulation technique works

PET/MRI scans show that a promising new treatment for neurological and psychiatric conditions works by triggering an increase in dopamine, researchers in France have reported. The finding supports the use of what’s called transcranial direct current stimulation for patients with dopamine dysregulations, such as schizophrenia, noted lead author Clara Fonteneau, PhD, of Claude Bernard University Lyon 1, and colleagues.
Whole-body PET shows how naloxone blocks opioids

6 days ago | auntminnie.com | Will Morton

A team at the University of Pennsylvania has shown for the first time how the opioid overdose treatment naloxone blocks mu-opioid receptors throughout the whole body. The study employed the groupâ€™s prototype long axial field-of-view scanner PennPET Explorer and reveals differences among men and women in how naloxone works, noted lead author Jacob Dubroff, MD, and colleagues.

Dear AuntMinnie Member,SPECT/CT myocardial perfusion imaging is a highly accurate method for diagnosing coronary artery disease, based on its ability to detect areas of the heart with ischemia and coronary artery calcium. Now, researchers suggest the modality may be used to identify patients who are more likely to benefit from specific therapies. Click here for more details.
SPECT/CT MPI may guide medical therapy in CAD patients

SPECT/CT myocardial perfusion imaging (MPI) can identify patients with coronary artery disease (CAD) who are more likely to benefit from specific therapies, researchers have reported. The study suggests that SPECT/CT MPI may have a role in guiding medical therapy for CAD, noted lead author Waseem Hijazi, MD, of the University of Calgary in Alberta, Canada, and colleagues.
PET scans identify people at early risk for cognitive decline

Amyloid PET scans in individuals with early signs of Alzheimer’s disease can identify those who are at higher risk of progressing to cognitive decline, researchers in Germany have reported. The finding is from an analysis of 197 individuals with “subjective cognitive decline” and highlights the value of PET scans for identifying people with pre-clinical disease, noted lead author Dr. Guilherme Kolinger, of Life Molecular Imaging in Berlin, and colleagues.
PET/MRI and DECT show abnormalities in long COVID patients

1 week ago | auntminnie.com | Will Morton

PET/MRI and dual-energy CT (DECT) have revealed heart and lung abnormalities in patients with long COVID, according to a study published April 30 in the Journal of Nuclear Medicine. The findings are from patients with cardiopulmonary symptoms lasting on average 303 days after infection, noted lead author Maria Trivieri, MD, PhD, of the Icahn School of Medicine at Mount Sinai in New York City, and colleagues.
