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. 

A study published this week in the Journal of the American College of Cardiology (JACC): Cardiovascular Imaging shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in computed tomographic (CT) and positron emission tomographic (PET) images than physicians.[1] The AI also performed well when the images were obtained from very-low-radiation CT attenuation scans. https://doi.org/10.1016/j.jcmg.2022.06.006

Artificial intelligence can objectively determine cardiac calcium scores faster than doctors

A new study shows artificial intelligence (AI) algorithms can more rapidly and objectively determine calcium scores in CT and PET/CT images than physicians.

Comparison of flurpiridaz F-18 PET, SPECT and angiography of the 60-year-old female patients in the Aurora trial. The SPECT scan appeared normal, but flurpiridaz was shown to be more sensitive and showed the ischemia from two blockages in the right coronary artery. The new radiotracer may help expand cardiac PET. #ASNC

Flurpiridaz data shows promise to expand and enhance cardiac PET

The biggest news from the American Society of Nuclear Cardiology (ASNC) 2022 meeting was positive late-breaking data on the phase 3 Aurora trial for the flurpiridaz (F-18) PET radiotracer agent.

Interview with Rebecca T. Hahn, MD, Professor of Medicine at Columbia University Irving Medical Center, Chief Scientific Officer of the Echo Core Lab at the Cardiovascular Research Foundation and Director of Interventional Echocardiography at the Columbia Structural Heart and Valve Center. She discusses some of the trends of growing use of interventional echocardiographic guidance in transcatheter structural heart procedures, the growing number of tricuspid valve procedures, and use of 3D ICE.

Cancer patients who undergo PCI face a higher risk of early mortality

Overall, PCI patients appear to face a higher risk of in-hospital mortality, 30-day mortality and in-hospital cardiovascular mortality if they present with an active or historical cancer diagnosis. The group's analysis included data from nearly 6.6 million patients.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
