PET/MRI may improve diagnosis of Cushing disease
By Will Morton
PET/MRI could become the diagnostic method of choice over MRI alone for identifying small pituitary tumors associated with Cushing disease.
March 29, 2024
T1-weighted postgadolinium MR images (A and C) and F-18 FET-PET/MR images (B and D) centered at pituitary before (A and B) and after (C and D) transsphenoidal surgery. This patient with Cushing disease showed clear focal uptake (B) but no clear lesion on previously obtained and accompanying MRI (A). Postoperative tissue analysis did confirm resection of small pituitary adenoma/PitNET, and postoperative F-18 FET-PET showed no residual uptake (D). Image courtesy of the Journal of Nuclear Medicine.
MRI reveals effects of risk factors on vulnerable brain regions
By Kate Madden Yee
MRI shows the effects particular risk factors such as diabetes, air pollution, and frequency of alcohol use have on "higher-order" brain regions located in the cerebral cortex, researchers have found.

To the left of the figure, the red-yellow color denotes the regions that degenerate earlier than the rest of the brain and are vulnerable to Alzheimer’s disease. These brain areas are higher-order regions that process and combine information coming from our different senses. To the right of the figure, each dot represents the brain data from one UK Biobank participant. The overall curve shows that, in these particularly fragile regions of the brain, there is accelerated degeneration with age. Image courtesy of Gwenaëlle Douaud, PhD, and Jordi Manuello, PhD.

The rise of theranostics: Part 1 -- Gaining momentum
By Liz Carey
FDA-approved radiopharmaceuticals have energized the field of theranostics. In part 1 of a series, experienced theranostics leaders offer implications of the latest clinical trials, how a theranostics clinic works, and advice for introducing theranostics.
