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.

Radiation in the cath lab: Tracking state-level regulations for cardiologists
Researchers hope these policies can be standardized in the future to help avoid confusion and improve clinician safety.
PFA market heats up as medtech companies announce new investments
While Kardium raised $250 million in an oversubscribed funding round, Field Medical raised $35 million. Both companies are focused on designing and developing new pulsed field ablation technologies to help treat challenging arrhythmias.
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.

Photoacoustic imaging could unseat fluoroscopy for guiding cardiac, other interventions

Johns Hopkins researchers have demonstrated the use of photoacoustic imaging to guide catheter-based cardiac interventions such as radiofrequency ablations used to correct arrhythmias.

How should physicians treat STEMI patients with COVID-19? A new study aims to find out

A new international research study will focus on treatment strategies and outcomes of ST-segment elevation myocardial infarction (STEMI) patients with known or suspected COVID-19.

‘A win-win for everyone’: Ultrasound technique provides improved arrhythmia assessments

A noninvasive ultrasound imaging technique can help healthcare providers localize atrial and ventricular cardiac arrhythmias, according to new research published in Science Translational Medicine. Could this method be added to clinical workflows in the near future?

Ultrasound-based imaging tool to pinpoint arrhythmia ‘win-win’ for patients, physicians

"This study presents a significant advancement in addressing a major unmet clinical need: the accurate arrhythmia localization in patients with a variety of heart rhythm disorders," one Johns Hopkins Medicine expert noted.

What the COVID-19 pandemic means for cath labs

The COVID-19 pandemic has changed the practice of cardiology as we know it, leading to supplies shortages, delayed procedures, and an at-risk patient population fearful of the road ahead. How has the outbreak affected cath labs?

ASNC monitoring potential Mo-99 supply shortages due to COVID-19

The president of the American Society of Nuclear Cardiology said there are no shortfalls reported at this time, but the organization is keeping an eye on the situation as more countries implement travel bans.

Medical software company gains FDA clearance for digital angiography platform

Budapest, Hungary-based Kinepict Health says its software produces higher-quality images and may ultimately make the technology more powerful and safer for patients.

What PET imaging can tell cardiologists about post-heart transplant survival

New research published in the Journal of Nuclear Medicine suggests PET myocardial perfusion imaging can be used to quantify myocardial blood flow and myocardial flow reserve, which have been proven as accurate indicators of adverse outcomes after heart transplants.
