A. Axial contrast-enhanced CT image shows 1.7 cm lesion (arrow) with ill-defined margin at left side of superior mesenteric artery. B. On axial T2-weighted image, mass is hyperintense to paravertebral muscle (arrow). C. On arterial phase post-contrast T1-weighted image, mass shows mild enhancement (arrow) compared to unenhanced image; enhancement pattern classified as early. D. On DWI with b-value of 800 mm2/s, mass is hyperintense (arrow) to paravertebral muscle. E. On ADC map, mass is visually hypointense (arrow) to paravertebral muscle. Findings indicate presence of qualitative diffusion restriction; lesion ADC value was 0.96 × 10−3 mm2/s. F. Axial image from CT performed 6 months after MRI shows increase in lesion’s greatest axial diameter by more than 5 mm (arrow), indicating soft tissue abnormality represents locally recurrent tumor.

MRI with DWI images showed higher sensitivity in detecting local recurrence after PDAC resection.

AI helps novice medical assistants perform high-quality echocardiograms

Novice medical professionals perform diagnostic quality echocardiograms with AI guidance 

 

Point-of-care ultrasound users are shown by where to put the probe and how to move it to perform optimal echocardiograms using the UltraSight artificial intelligence (AI) software. The goal is to reduce variability between sonographers and increase diagnostic quality of the images.

In a blind pilot study, inexperienced users successfully captured images for 100% of patients using AI guidance.

As war in Ukraine continues, it's business as usual for many U.S. healthcare companies in Russia

Russian armored vehicle captured recently by the Ukrainian army. Despite the continuation of the war, economic sanctions against Russia and many companies pulling out of Russia, some U.S. healthcare companies remain there to do business.

Since the Russian invasion of Ukraine began in late February, the Yale School of Management has been tracking more than 1,200 companies that do business in Russia.

ACR working with FDA and HHS to help address imaging contrast shortage
