Can Chat GPT accurately refer patients to IR for treatment?
By Chloe G. Cross, MD
In interventional radiology (IR), most of us quickly become accustomed to needing to explain what we do. But how do patients get their own information about IR, if at all?

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.
Deep learning helps distinguish benign vertebral fractures on CT
By Kate Madden Yee
A deep-learning algorithm used with CT imaging can differentiate between benign and malignant vertebral fractures, researchers have found.

Overview of the automated deep learning-based pipeline. Multidetector CT images show the (A) original data, (B, C) vertebral segmentation, and (D-F) vertebral labeling during preprocessing. Images and caption courtesy of the RSNA.
Cryoablation effective in women with breast cancer

How has virtual interviewing impacted residency matches?
By Will Morton
Virtual interviews implemented due to the COVID-19 pandemic do not appear to have shifted the geographic distribution of interventional and diagnostic radiology residents.

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.

Radiologists, RTs, and the art of forensic imaging
By Kate Madden Yee
Forensic radiologists and radiologic technologists apply their expertise to imaging exams intended to lay bare the causes of trauma. AuntMinnie.com spoke to two experts about the state of the specialty.

The axial images on soft tissue windows demonstrate the dilated bowel, a common finding in decomposition. The images with the circles denote the incarcerated hernia. The larger photo is the incarcerated and strangulated bowel at autopsy. Images and caption courtesy of Jamie Elifritz, MD.
How underrepresented are women in radiology?
By Amerigo Allegretto
Women in North America remain underrepresented in radiology subspecialties, but departments can implement strategies to address these disparities.
