Researchers try to take the guesswork out of sarcoidosis
Tuesday, December 2 | 11:10 a.m.-11:20 a.m. | SSG08-05 | Room S504CDSarcoidosis can be a difficult disease to diagnose, with FDG-PET/CT scans occasionally mistaking inflammation for cancer. To address this issue, researchers from India conducted a study that included 50 cancer patients and 14 sarcoidosis patients with no malignancy.

Promising new MRI technique provides insight into stroke
Researchers from several institutions have used a 21-tesla preclinical MR spectroscopy scanner to develop a new technique for evaluating patients for stroke and possibly neurodegenerative diseases. They believe the protocol could be migrated to 3- and 7-tesla MRI scanners being used clinically.

Can AI help chest DDR achieve clinical adoption?
By Will Morton
Chest dynamic digital radiography (DDR) may have received a boost toward clinical use in patients with lung disorders, with researchers developing AI to perform time-consuming analysis involved in the technology.

(a) Raw example of a dynamic digital radiograph. (b) Contrast equalization using contrast-limited adaptive equalization shows improved anatomical visualization. (c) Training data is generated through manually labeling using SLEAP’s graphical user interface. (d-e) Neural network detection schematic. For each quadrant a series of two networks were used. The first identifies the quadrant center, the second using input of the first, then identifies individual anatomical landmarks within a quadrant. (d) Four neural networks were trained, each with the objective of identifying a chest quadrant centroid. The four separate quadrants are visualized as colored boxes (right upper quadrant, green; right lower quadrant, blue; left upper quadrant, red; left lower quadrant, yellow). (e) Serial centroid then anatomical identification. Two quadrant examples showing confidence maps of trained neural networks identifying quadrant centroids (left) and then anatomical confidence maps (right).

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.
March 27, 2024
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.
