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.

AI turns low-quality MRI scans into helpful heart images
A team of biomedical engineers, radiologists and cardiologists has developed a new AI model capable of restoring low-quality cardiac MRI scans.
Johnson & Johnson MedTech faces threat of permanent injunction after losing antitrust case
After being ordered to pay $442 million in damages—a ruling the company has said it may appeal—Johnson & Johnson MedTech is now facing the possibility of a permanent injunction that could impact certain business practices. A hearing is scheduled for July.
Cardiologists, radiologists and surgeons share ‘landmark’ document on assessing prosthetic heart valves with CT
RSNA and several other industry societies have shared a new expert consensus document on the significant value of cardiac CT. Echo remains an effective first-line imaging option, the groups wrote, but CT can make a big impact as well.
AMA resolution backs expanded low-dose CT screenings for lung cancer, heart risk
Dana Smetherman, MD, CEO of the American College of Radiology, discusses the policy, which urges for more robust promotion of low-dose CT as a public health tool.
Angiographic catheters recalled due to safety risk
The new Class I recall includes nearly 27,000 devices that could potentially experience a harmful defect during use.

IVUS-guided PCI associated with improved outcomes

Despite the improved outcomes, utilization of IVUS-guided PCI remains low and inconsistent.

CCTA tops stress imaging for spotting key plaque features and may assist with heart disease care

The team analyzed more than 600 patients included in a trial investigating CT-based atherosclerotic determinants of coronary artery disease for their research, published in JAMA Cardiology.

Thousands of MRI scans help experts understand 500-year-old heart mystery first described by Leonardo da Vinci

Artificial intelligence also played a large role in discovering how this intricate network of muscle fibers can influence health, experts explained in Nature.

Physicians are more likely to predict heart attack than stroke when analyzing CAC scans

UT Southwestern researchers looked over data from more than 7,000 patients for their research.

Underutilized imaging modality boosts care for patients with suspected coronary artery disease

The multicenter study tracked data from more than 1,600 patients in 11 different states.

Promising outcomes reported for transcatheter mitral valve-in-valve replacement

The overall procedural technical success rate, researchers reported, was 96.8%.

AI-powered ECGs improve care for high-risk heart patients

The study, published in Circulation: Arrhythmia and Electrophysiology, included data from more than 1,600 patients who presented at the ED with shortness of breath.

Female smokers four times more likely to suffer brain aneurysm than nonsmokers

That risk only grew for those with underlying hypertension, suggesting women between 30 and 60 years old may benefit from screening, researchers wrote recently.
