Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

CT procedure shown to reduce need for invasive cardiac testing

In a study, CT-FFR was shown to reduce the need for invasive tests to measure coronary artery blockage from 74.5% to 25.5%.

First-in-human trial shows potential of guiding CABG with cardiac CT and AI—no ICA required

An independent heart team blinded to ICA results was able to deliver helpful guidance for CABG procedures for 99.1% of patients using just CCTA and FFRCT alone. This approach is safe and feasible, researchers wrote, and the next step is to gather additional data.

Cardiology, radiology groups urge insurance provider to rethink imaging policy

SCAI and four other major healthcare organizations signed a joint letter in support of intravascular ultrasound. 

Avicenna.AI, a French artificial intelligence (AI) startup co-founded by a radiologist, has received U.S. Food and Drug Administration (FDA) clearance for two new offerings designed to automatically identify cardiovascular findings in CT scans, CINA-iPE and CINA-ASPECTS.

Radiology AI company gains FDA clearance for new CT offerings focused on PE, stroke

The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.

Video interview with Tim Bateman, MD, co-director, cardiovascular radiologic imaging program, Saint Luke's Mid America Heart Institute and an American Society of Nuclear Cardiology (ASNC) past-president, explaining the role of SPECT into the future as PET becomes more popular. A new look at PET vs SPECT.

SPECT still has an important role to play in nuclear cardiology

"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

Expert calls for education, research to spur adoption of intravascular ultrasound

Eric Secemsky, MD, from Beth Israel Deaconess Medical Center and Harvard Medical School, says a lack of hands-on training and reimbursement challenges are hindering the adoption of IVUS.

Kumar Madassery, MD, director of peripheral vascular intervention and critical limb ischemia (CLI) program at Rush University Medical Center in Chicago, explains techniques and tools used to restore blood flow to the foot to help foot wounds heal and prevent amputation. He is part of a campaign to raise awareness through the PAD Pulse Alliance.

Interventional techniques can help limit amputations among CLI patients

Kumar Madassery, MD, detailed some of the techniques and tools used to restore blood flow to the foot to help foot wounds heal and prevent amputation.

Breast arterial calcifications (BACs) identified on screening mammograms may help identify women who face a heightened risk of developing cardiovascular disease (CVD), according to a new analysis published in Clinical Imaging.

Incidental breast calcifications on mammograms linked to much higher risk of cardiovascular disease

These findings may say a lot more about a patient's long-term health than clinicians realized.
