Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

AI/radiologist combo improves breast cancer detection, decreases workloads

The new two-part AI system is based on a decision-referral approach and triages mammograms based on quantification of uncertainty.

CT scans set to take flight in new project that aims to integrate imaging into air ambulances

The Norwegian Air Ambulance Foundation is using a newly acquired five-bladed H145 helicopter to develop and test the technology and hopes to have a CT scanner implemented into it in the next four to five years.

AI boosts accuracy when discriminating between malignant and benign ovarian tumors on MRI

Out of three trained and tested models that incorporated varying features, the model that combined clinical and radiomics features to predict malignancy exceeded the others in accuracy, precision and sensitivity.

Experts use MRI to pinpoint link between pediatric TBI and cognitive impairment

At least one white matter tract with reduced volume—most often in midline white matter structures including the corpus callosum—was observed in 28% of TBI patients.

Mobile X-ray Leaps into the Future with New Innovations from Konica Minolta Healthcare

Dynamic Digital Radiography and the new glassless AeroDR flat panel detector will be available on the mKDR Xpress Mobile X-ray System

Examples of new plaque reporting in the CAD-RADS 2.0 document. Left, an example from CAD-RADS 2 / P2 plaque burden with mild coronary stenosis (25-49%). Right, example of a CAD-RADS 5/ P3, with a focal, non-calcified occlusion of the proximal RCA (arrow) and severe amount of plaque (P3). #CADRADS #YesCCT #CTA #CCTA

New CAD-RADS 2.0 reporting for coronary CTA offers patient management recommendations

The document includes updated classification to established a framework for stenosis, plaque burden and plaque modifiers, including assessment of CT-FFR or myocardial CT perfusion.

Contrast shortage update: Supplies could continue to lag until September

GE previously indicated that the iodinated contrast shortage would resolve by the end of June.

AI model outperforms rads at distinguishing malignant from reactive lymph nodes on US

“Visual techniques are not enough to correctly classify nodes in patients after COVID-19 vaccination,” experts shared in EJR.

Around the web

Harvard’s David A. Rosman, MD, MBA, explains how moving imaging outside of hospitals could save billions of dollars for U.S. healthcare.

Back in September, the FDA approved GE HealthCare’s new PET radiotracer, flurpiridaz F-18, for patients with known or suspected CAD. It is seen by many in the industry as a major step forward in patient care. 

After three years of intermittent shortages of nuclear imaging tracer technetium-99m pyrophosphate, there are no signs of the shortage abating.
