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.

90 second scan analyzes emergency department chest pain

A new magnetocardiography modality performed similarly to stress testing and coronary angiography in diagnosing unexplained chest pain, according to a new pilot study.

New Cardiac Cath Lab Embraces Enterprise Imaging

Sponsored by Sectra

When the cardiac and neurovascular catheterization lab at Riverside University Health System Medical Center (RUHS-MC) treated its first patient last February, the opening represented many things to many people.

New AAA findings suggest follow-up imaging protocols may need updating

A blood clot in the aortic wall leads to more accelerated and life-threatening growth of abdominal aortic aneurysms. In light of the research, clinicians may need to shorten the time between surveillance.

Simple ECG score helps estimate MI infarct size

A simple ECG score could help physicians estimate infarct size in patients with prior MI, according to work published Jan. 24 in the Journal of the American Heart Association.

Combining top CT stroke analyzers accurately predicts thrombectomy outcomes

Stroke patients with a favorable imaging profile on both non-contrast CT and CT perfusion achieved better 90-day functional independence rates than all other groups, according to results of the SELECT study.

CT angiography cost-effective for detecting LVO in patients with minor stroke

CT angiography—preferably followed by immediate thrombectomy—was cost-effective and beneficial for triage in a recent study of patients with acute minor stroke, researchers reported in Radiology Jan. 14.

Cardiac MR comparable to FFR for evaluating nonculprit lesions after STEMI

A study published in the latest edition of JACC: Cardiovascular Imaging suggests cardiac magnetic resonance imaging can be as effective as measurements of fractional flow reserve in evaluating nonculprit lesions after STEMI.

CTA is a cost-conscious approach to improve outcomes in minor stroke patients

Using CT angiography to screen for large vessel occlusion, followed immediately by thrombectomy, proved to be the cheapest option and yielded the most quality-adjusted life years.
