Vision transformer AI model boosts PET/CT imaging of cancer
This study included imaging from 143 patients with active abdominopelvic cancer and 64 patients without any active cancer who underwent whole-body PET/CT scans at Osaka University Hospital between January 2020 and August 2021.Using this data, the researchers trained a previously developed ViT-B/16 model without modifications to classify the PET/CT images as “positive” or “negative” (malignant or benign). Next, they compared the ViT’s performance with two baseline CNN models, called DenseNet and EfficientNet, on 4,852 test PET/CT images.Predictions and Grad-CAMs of ViT-based models on sample PET/CT, PET, and CT te...

NIH: Occupational radiation dose to RTs needs careful monitoring

And although these procedures benefit patients by reducing recovery time compared with conventional surgery, they expose medical staff to significant radiation.Milder and colleagues assessed radiation dose to technologists assisting wi...

CT-FFR reduces invasive procedures for coronary artery blockages
CT fractional flow reserve (CT-FFR) imaging identifies patients with coronary artery blockage or narrowing who could benefit from revascularization -- and helps reduce the unnecessary use of invasive procedures, researchers have found.
A team led by Mangun Kaur Randhawa, MD, of Massachusetts General Hospital in Boston reported that individuals with significant narrowing and/or blockages identified on coronary CT angiography (CTA) who underwent CT-FFR had lower rates of invasive coronary angiography and ensuing percutaneous coronary intervention than patients who were not referred for a CT-FFR. The research was published A...

Experts: Consider BMI when imaging patients with chest pain
A patient’s body mass index (BMI) has a significant effect on how much radiation exposure they receive from chest imaging in cases of suspected cardiac ischemia, according to a study published April 9 in the Journal of the American Heart Association.
Cardiologists at Saint Luke's Mid America Heart Institute in Kansas City, MO, found that as BMI increases, so too does radiation exposure, although PET offers the least variability, followed by SPECT, and then coronary CT angiography (CCTA). The finding is key to providing “patient-centered” care, the group wrote.
“These data may be helpful to generate more accurate ...

CEUS adds to locoregional therapy for liver disease
Contrast-enhanced ultrasound (CEUS) can improve locoregional therapy for treating metastatic disease of the liver, according to early study results presented April 10 at UltraCon.
In her presentation, PhD candidate Corinne Wessner from Thomas Jefferson University in Philadelphia, PA, highlighted initial findings from her team’s ongoing work suggesting that microbubble destruction from CEUS triggering is safe and well-tolerated among patients with intrahepatic cholangiocarcinoma (ICC) and metastatic liver disease who also receive transarterial radioembolization with yttrium-90 (Y90-TARE).
“When we add the ultrasound-t...

Simpson Interventions OCT-guided system gets FDA nod
The U.S. Food and Drug Administration (FDA) has granted Simpson Interventions' Acolyte Image Guided Crossing and Re-Entry Catheter system Breakthrough Device Designation.
The system facilitates the placement and positioning of guidewires and catheters within the coronary vasculature for treating patients with coronary chronic total occlusions who continue to experience symptoms following medical treatment. It provides real-time optical coherence tomography visualization, supporting effective guidewire placement within the target vessel's true lumen and subsequent revascularization.
Simpson Interventions said it is workin...

SimonMed to integrate Infervision tech into its facilities
SimonMed Imaging is integrating Infervision’s AI-powered InferRead Lung CT.AI technology into its facilities.
The move aims to improve the identification of pulmonary nodules and to provide 3D characterization and comparison of nodules. It will be integrated into CT chest scan readings, including those for lung cancer screening.
The technology automatically displays boxes around nodules in a new series providing standardized reporting of all nodule characteristics including image number, type of nodule, and volume. It also assesses previous exams to track changes in diameter and volume. In cases where pneumonia is su...

UltraCon: Work-related MSK disorders tied to sonographer burnout
Work-related musculoskeletal (MSK) disorders are tied to work-related burnout among sonographers, according to research highlighted April 10 at UltraCon.
In her presentation, Jennifer Bagley from the University of Oklahoma Health Sciences Center discussed her team’s results showing that many sonographers who score high on the Oldenburg Burnout Inventory also reported having a work-related musculoskeletal disorder.
“It presents an opportunity for administrators to think about these two conditions together and think thoughtfully about how they can help sonographers and not lose staff,” Bagley said.Jennifer Bagley fro...

AI can be used to'rule-out' breast cancer on mammography
A deep-learning algorithm can rule out the presence of breast cancer on screening mammograms, improving specificity and yielding significant workflow and downstream savings, according to research published April 10 in Radiology.
A team of investigators led by first author Stefano Pedemonte, PhD, of AI software developer Whiterabbit.ai, and senior author Richard Wahl, MD, of the Mallinckrodt Institute of Radiology, trained and tested a deep-learning algorithm using over 160,000 2D full-field digital mammography exams. They found their model could sharply reduce the number of screening mammograms requiring radiologist revie...
