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.

FDA grants special recognition to AI software used to diagnose rare form of hypertension

The FDA has granted a breakthrough device designation for an artificial intelligence (AI) pattern recognition software being developed by Bayer and Merck & Co. in New Jersey that can identify signs of chronic thromboembolic pulmonary hypertension (CTEPH)—a rare form of hypertension—in CT pulmonary angiography (CTPA) scans, according to a Dec. 3 press release.

Radiologist pinpoints where cardiac 3D imaging needs improvement

“We’d better make some rules because otherwise, you can have willy-nilly 3D printing...you can 3D print off your iPhone if you have the right hook-ups, right? But we don’t want that. We want to do really high-quality work," said Frank J. Rybicki, MD, PhD, at the American Heart Association’s 2018 Scientific Sessions in Chicago according to a report by Cardiovascular Business.

CT analysis before percutaneous PVI aids heart disease patients

Performing CT analysis prior to percutaneous pulmonary valve implantation (PPVI) in patients with congenital heart disease (CHD) may assist physicians in detecting those who are most at-risk for coronary artery compression during the operation.

New trial may allow CMAs to perform echocardiograms with AI-guided ultrasound

The study will determine whether CMAs can obtain echocardiograms that, when reviewed by cardiologists, will detect more patients with cardiac disease compared to a standard physical examination with an electrocardiogram (ECG) in a primary care setting, according to a Northwestern University press release.

Updated cholesterol guidelines criticized for coronary artery CT scan recommendation

Updated cholesterol guidelines from the American Heart Association and the American College of Cardiology suggest a more personalized approach to stroke risk assessment and address criticisms of five-year-old recommendations, according to CNN. But one new recommendation has generated pushback.

56K angina patients in UK denied CTs in 2017 due to radiologist shortage

Last year, more than 56,000 angina patients across the U.K. were denied life-saving CT heart scans due to the continuing shortage of radiologists and scanners, according to data released Nov. 8 by the Royal College of Radiologists (RCR) and the British Society of Cardiovascular Imaging (BSCI), published in The BMJ.

4D flow MRI may improve automated valve tracking in congenital heart patients

Researchers from the Netherlands demonstrated, in a study published Oct. 30 in Radiology, that four-dimensional (4D) flow MRI with automated cardiac valve tracking reduces analysis time and improves reliability of valvular flow quantification compared to manual valve tracking in patients with congenital heart disease.

New Apple patent could transform 3D printing in medical imaging

A patent filed in 2014 by Apple Inc. for a new method to print three-dimensional (3D) models using triangular tessellation was recently approved by the U.S. Patent and Trademark Office on Tuesday, Oct. 23, according to a report by TechCrunch.com.

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
